(I'm really impressed by the speed one gets answers from this mailing list, 
Thanks!)

This got a bit complicated, because I'm no experienced C-programmer. 
Fortunately one knows somebody who knows more. We found that pls was declared 
static, so inaccessible and out of pure intuition we decided to try out plsc 
which is also a PLStream. And it worked! The temporary file is now still 
open, but it doesn't grow anymore. 
Here is what I did in my application code:
...
#include "plstrm.h"
extern PLStream *plsc;
....
plinit();
plsc->plbuf_write=0;
....

I'm not sure if this was the right (or the best) way to do it, but I think I 
can be happy with it. Thanks to the developers of those cool libraries which 
make programming a lot more fun!

The next challenge will be user interaction for which I will need an 
eventhandler for our window. Just don't know yet how to accomplish this 
stuff.

Best regards,
Jay

PLplot uses a temporary file to store the plotting commands in. This is
used to recreate the image when necessary, but of course, in your case,
the whole history is stored ... That is an unforeseen consequence. 

I have no solution right now. Perhaps it is possible to turn off the
temporary file - you do not really need it. But you would have to
check the code.

Heh.  That looks like the plot buffer.  As you create a plot under X, the plot
buffer pseudo-device is written to, so that on window expose or redraw events,
the prior contents of the window can be recovered.  It's closed at every
end-of-page, and my guess is that you aren't issuing any.. LOL.  There really
should be a size limitation on it though.. >1G is way, way too big. :)

Although there is no API control for this, fortunately you do have access
through the plplot stream pointer.  You can disable writing to the plot buffer
entirely by setting pls->plbuf_write to 0.  Or keep it writing by default but
control its contents through manipulating pls->plbufFile.  See src/plbuf.c for
more info.

[Plplot-general] hard disk filling up

[Jay C. <jea...@is...>]

hello again!
to answer my previous question:
My 50 channel oscilloscope application is feasible with plplot as graph 
library. It is really fast. I use the polygon fill function to erase previous 
plotted data.

but another problem:
If I let the program run a long time my hard disk fills up. It took some time 
to find out what file would get so huge, because the file doesn't show up in 
the filesystem, because it is already deleted. (funny phenomenon). 
#lsof -c scope
COMMAND   PID USER   FD   TYPE     DEVICE       SIZE    NODE NAME
(...)
scope   32031 root    6u   REG        8,3 1415630848   19684 /tmp/tmpfXiOQuk 
(deleted)

I suspect that pouring that many data so fast into the X-server or the plplot 
device perhaps causes it to build up a queue which grows ever bigger. But 
however my application runs normally and everything I want it to draw gets 
drawn even after the disk is saturated.

So where does the tempfile come from, why is it deleted (it immediately goes 
away when the program exits) and what exactly is its purpose? How could I 
correct this? 

Thanks in advance for any help.

[Plplot-general] New CVS distribution tarball available

[Rafael L. <rla...@us...>]

A new CVS snapshot distribution tarball for PLplot is available at the usual
place:

    http://people.debian.org/~rafael/plplot.html

The tarball name is plplot-5.2.1.cvs.20040114.tar.gz.  This is a test
tarball, not yet the promised release candidate one, because we are testing
some linking issues in the generation of Octave bindings on MacOS X.  Users
of this system are then encouraged to test the tarball.

There has been some improvements in relation to the last cvs tarball, most
notably the completion of the f77 bindings and the improvement of pkg-config
support.  The configuration process has been made more robust.

A true release candidate tarball will be released as soon as the remaining
issues will be .

Fortran API change as discussed on the list.

All plshade[0-2] and plshade fortran calls now have a last parameter which
is the first dimension of the 2D arrays.  This extra parameter is similar to
what is currently done for the fortran versions of plmesh, plmeshc, plot3d,
plot3dc, plshades[0-2], and plshades.  It allows large static 2D arrays to
be dimensioned in fortran apps which call these PLplot functions (plcon[0-2]
and plcont have similar possibilities for large static arrays done a
different way).  This in turn allows smaller areas of the fortran array to
be populated as needed (interactively from input, say) without having to
recompile for every change in size of the defined part of the array.

These recent Fortran API changes have been tested for fortran examples 15
and 16a (now both changes to use static arrays dimensioned larger than the
defined area), and identical results to the previous are obtained.
Furthermore, memory management has been changed substantially for fortran
plshade[0-2] and plshade, and valgrind applied to fortran examples 15 and
16a show no problems with these memory management changes.

Restructured the pkg-config support.

Everything that was scattered across pkgcfg/gen-pc-files.sh and
pkgcfg/Makefile.am (shell code) as well as pkgcfg/plplot-master-pc.in (.pc
file template) is now regrouped in the single Perl script
gen-pc-files.pl.in, configurable through configure.

Since Perl is needed now, the code in configure.ac was changed, such that
pkg-config support is disabled if Perl cannot found in the system. Also the
pkg-config section in configure.ac was moved after the call to
CHECK_PROG(perl).

The Tcl/Tk specific cflags for include directories are now integrated in
plplot*-tcl.pc.  The file examples/tk/Makefile.examples.in was changed
accordingly.

Commit from rlaboiss (2004-01-06 13:38 CET)

Variable substitution for generation of bindings/octave/plplot_octave.h is
now done with help of autoconf/automake.

A new AC_SUBST variable called DEFINE_PL_DOUBLE is defined in configure.ac,
which is set to "#define PL_DOUBLE" if $with_double == yes, or a null string
otherwise.

The old file plplot_octave_org.h has been renamed to plplot_octave.h.in and
its name is included in the AC_CONFIG_FILES list in configure.ac.  It
contains the token @DEFINE_PL_DOUBLE@ at the place of the old REPLACEME
token.

Since everything is set up automatically by Automake, the rule for building
plplot_octave.h is removed from bindings/octave/Makefile.am.  Also, there is
no need to include plplot_octave.h in the CLEANFILES list.

Fix for the "centuries old" very irritating bogus warning messages about

The problem was, itclDecls.h apparently is not meant to be included except
from itcl.h, or after itcl.h has been included first.  So, this dependency
needed to be accounted for, and fortunately there is an autoconf construct
to do it.  As is often the case with these things, very simple once you know
what to do.

So to reproduce the previous plplot config file behavior, do:
$ CONFIG_SITE=~/config/cf_plplot.in ./configure

The latter is the *only* way currently to set prefix via a config file.  In
this case, set ac_default_prefix appropriately ("pl_prefix" was previously

Re: [Plplot-general] deleting only plotted data lines

[Vince D. <vi...@sa...>]

I did some real-time stuff with Plplot's tkwin widget several years back,
and found it pretty fast.  I tried various approaches, including drawing
the previous data in the background colour to delete it.  I even hacked a
scrolling feature to create a kind of moving time-series.

All of the above worked reasonably well, although the simple approach of
replotting the entire graph was also quite reasonable in speed.

[Plplot-general] deleting only plotted data lines

[Jay C. <jea...@is...>]

I'm working on a real time application. (althoug i'm afraid that perhaps 
things will be too slow in the end). I tried to figure out what would be the 
most time-effective way to begin a new plot with the same axes and legend. 
That is delete only the plotted representation of the data and not having to 
initialize the rest.

The method used by "win3" is:

msdev\src only contains the Windows driver, so you probably only need  
the files in src (and the driver source files in ...\drivers)

(Note: I will be looking into the problem of using the win3 driver with
cygwin - something akin to what you are trying to do)

[Plplot-general] New CVS distribution tarball available

[Rafael L. <rla...@us...>]

A new CVS snapshot distribution tarball for PLplot is available at the usual
place:

    http://people.debian.org/~rafael/plplot.html

The tarball name is plplot-5.2.1.cvs.20040104.tar.gz.  This tarball fixes a
couple of issues pending since the last release (5.2.1.cvs.20031231). In
particular, compilation on MacOS should go much smoother now and the
pkg-config is hopefully fully operational.  See the ChangeLog below for
details (sorry, Joao, your two last commits regarding the Octave bindings
did not get in).

Big thanks to everybody who helped with this cvs release, in particular
Alan, who rushed with the F77 API extension and building fixes, as well as
for his systematic tests of all my changes.  Without Alan's hard work the
present release would not be possible.

This tarball can be considered as a *_serious_* release candidate for the
next version of PLplot.  We do not have yet a precise schedule for the
release, but I foresee somewhere around the end of January.  This will give
time to all our testers to catch up and also for me to do the final release
clean-up (boring work, like: updating the copyright notices, writing the
announcement, etc.)

I hope that by the end of January CVS HEAD will not be much changed,
otherwise, I will have to make a CVS branch for the release.

My preference is that the next release have version number 5.2.2, unless
good arguments for 5.3.0 are presented.

==== ChangeLog plplot-5.2.1.cvs.20031231 -> plplot-5.2.1.cvs.20040104 ====


Commit from rlaboiss (2004-01-04 18:45 CET)
--------------------

Change the logic of setting PLPLOT_MUTEX_RECURSIVE, by making $host_os =
linex* the special case, and not $host_os = darwin

  plplot  configure.ac  1.140
  plplot  sysloc.in     1.64


Commit from rlaboiss (2004-01-04 13:18 CET)
--------------------

Improve portability of libpthread-related code

In sysloc.in, a new AC_DEFINE macro is created: PLPLOT_MUTEX_RECURSIVE.  In
darwin systems it will expand to PTHREAD_MUTEX_RECURSIVE, otherwise to
PTHREAD_MUTEX_RECURSIVE_NP.

Also, in xwin.c, pthread_mutexattr_setkind_np() was changed to
pthread_mutexattr_settype(), since this should work in all systems.

  plplot  sysloc.in       1.63
  plplot  drivers/xwin.c  1.115


Commit from airwin (2004-01-04 04:06 CET)
------------------

Eliminate "p" examples from test because they user higher-level octave
programming that demands octave-2.1.50 or better (which not all users have).

We have kept the remaining "x" examples for this test.  They are worth
having since they directly test the octave interface to libplplot and they
work for octave-2.0.x or later.

  plplot  test/test_octave.sh  1.12


Commit from airwin (2004-01-04 02:13 CET)
------------------

Took Rafael's advice and moved all AC_SUBST macros out of conditionals
(since apparently they are executed regardless, and they can lead to
shell problems if they are the only macro inside the conditional).

  plplot  configure.ac  1.139
  plplot  sysloc.in     1.62



  Commit from rlaboiss (2004-01-04 01:09 CET)
--------------------

Fixed use of rpath option in compile commands under the pkg-config paradigm.

A new AC_SUBST variable RPATHCMD is created in configure.ac containing
"-Wl,-rpath -Wl,$libdir".  This solution has portability issues, but should
work now for a large spectrum of systems/compilers.  I will revisit this
issue in the future.

  plplot  configure.ac                       1.138
  plplot  examples/c/Makefile.examples.in    1.17
  plplot  examples/c++/Makefile.examples.in  1.16
  plplot  examples/f77/Makefile.examples.in  1.17
  plplot  examples/tk/Makefile.examples.in   1.12


Commit from airwin (2004-01-03 21:56 CET)
------------------

Get rid of lots of "default" linking cruft in configure.ac. Instead, use
ADD_TO_INCS and ADD_TO_LIBS in sysloc.in.

There is more of this to do for the (i)tcl/tk flags, but that is a more
complicated situation, and in any case tcl/tk configuration needs a complete
rewrite in other ways as well.

  plplot  configure.ac  1.137
  plplot  sysloc.in     1.61


Commit from airwin (2004-01-03 21:44 CET)
------------------

Fixed continuation issue.

  plplot  examples/tk/Makefile.examples.in  1.11


Commit from rlaboiss (2004-01-03 20:22 CET)
--------------------

* Created the AC_SUBSTituted variable PKG_CONFIG_ENV. This variable replaces
  the previous PKG_CONFIG_PATH.  It defaults to the usual
  "PKG_CONFIG_PATH=$PKG_CONFIG_DIR", but can be overriden by using the
  environment variable of same name.  This is done in debian/rules for
  instance , since setting PKG_CONFIG_PATH is not necessary in Debian.  The
  echo from the make command in the installed examples directories is much
  cleaner now (in Debian, at least):

      $ cd examples/c
      $ make -n x01c
      gcc x01c.c -o x01c  `pkg-config --cflags --libs plplotd`


* Added $(RPATH) to the compilation command under the pkg-config approach in
  the examples/*/Makefile.examples.in.


* In examples/tk/Makefile.examples.in, added include flags specific to
  Tcl/Tk in the compilation command under the pkg-config approach.  A new
  variable TCLTKINCCMD was created, which is also used in INCLUDEANDLIB.

  plplot  configure.ac                       1.136
  plplot  debian/changelog                   1.64

  plplot  examples/f77/Makefile.examples.in  1.16
  plplot  examples/tk/Makefile.examples.in   1.10


Commit from airwin (2004-01-03 18:14 CET)
------------------

Add top-level Makefile to installed examples tree.  To do this and to
avoid name clashes with existing Makefiles, the configurable file is
called Makefile.examples.in which is configured to Makefile.examples which
is renamed on install to Makefile.

The resulting Makefile in the installed examples tree is of considerable
usefulness.  Previous instructions were "cd c; make; cd c++; make; cd f77;
make; cd tk; make; cd ..; ./plplot-test.sh".  Those are now simply replace
(in the _installed_ examples tree or a copy of it) by "make;
./plplot-test.sh".  Also, the subdirectories are now configured in the
generated Makefile so the instructions don't have to be modified if, e.g.,
fortran, is not enabled.

  plplot  configure.ac                   1.135
  plplot  examples/.cvsignore            1.4
  plplot  examples/Makefile.am           1.5
+ plplot  examples/Makefile.examples.in  1.1


Commit from airwin (2004-01-03 16:58 CET)
------------------

Include 18th fortran example in plplot-test.sh tests.

  plplot  test/test_f77.sh  1.6


Commit from airwin (2004-01-03 05:39 CET)
------------------

Bug fix for unique prefix case: put PKG_CONFIG_PATH=$(PKG_CONFIG_PATH) inside
backwards quotes rather than at start of command line.

  plplot  examples/c/Makefile.examples.in    1.15
  plplot  examples/c++/Makefile.examples.in  1.14
  plplot  examples/f77/Makefile.examples.in  1.15
  plplot  examples/tk/Makefile.examples.in   1.9


Commit from airwin (2004-01-03 04:33 CET)
------------------

* Define the expanded variables LIB_HARDDIR and DRV_HARDDIR (expanded or
"hard" versions of LIB_DIR and DRV_DIR).

* These variables are used to configure bindings/*/pkgIndex.tcl which are
then concatanated into bindings/pkgIndex.tcl.  The latter file is installed
in the $prefix/share tree.  It allows needed PLplot libraries or plug-in
drivers to be found in the $prefix/lib tree directly from the tclsh or wish
environments using the lappend command.

* With these changes (which adjust for moving all the installed PLplot
tcl/tk scripts from the $prefix/lib tree to the $prefix/share tree) I can
once again execute PLplot commands from tclsh and wish environments
following the instructions in examples/README.tcldemos and
examples/README.tkdemos.

  plplot  configure.ac                        1.134

  plplot  bindings/tk/pkgIndex.tcl.in         1.9
  plplot  bindings/tk-x-plat/pkgIndex.tcl.in  1.9


Commit from airwin (2004-01-03 04:16 CET)
------------------

Change documentation from "lib" to "share" location used for lappend command.

  plplot  examples/tcl/README.tcldemos  1.10
  plplot  examples/tk/README.tkdemos    1.12


Commit from airwin (2004-01-03 03:10 CET)
------------------

Get rid of trailing whitespace on the list of executables that was screwing
up the make.

  plplot  examples/f77/Makefile.examples.in  1.14


Commit from rlaboiss (2004-01-03 01:43 CET)
--------------------

Preparation to Debian release 5.2.1.cvs.20031231-2

  plplot  debian/changelog  1.63
  plplot  debian/rules      1.43


Commit from rlaboiss (2004-01-03 01:42 CET)
--------------------

Fixed several issues related to the *_DIR variables

* Made the treatment of the *_DIR even more systematic now.  These variables
  are really intended to AC_SUBSTitution in the Makefile.in generated from
  Automake.  As such, they are always relative, never hard paths.

* When it is needed to get them substituted as hard paths (like in config.h
  via AC_DEFINE_UNQUOTED, or in the examples/*/Makefile.examples), then new
  variables are defined.  In particular, this is the case of the new
  variables INCLUDE_DIR_CMD and LIB_DIR_CMD, which should be used in
  examples/*/Makefile.examples and fix the problems with the plplot_libtool
  approach.

* In order to help expansion of hard paths, the macro EXPAND_EXPRESSION was
  added to acinclude.m4.

* Support for pkg-config was added to examples/tk/Makefile.examples.in.
  Build of the examples in examples/tk with pkg-config is not working yet,
  though.  The Tcl/Tk include directories are not being included.  I will
  fix this later.

  plplot  configure.ac                       1.133
  plplot  acinclude.m4                       1.12
  plplot  examples/c/Makefile.examples.in    1.14

  plplot  examples/f77/Makefile.examples.in  1.13
  plplot  examples/tk/Makefile.examples.in   1.8
  plplot  pkgcfg/Makefile.am                 1.8


Commit from airwin (2004-01-03 00:31 CET)
------------------

* Stylistic changes: (comments, indentation, do loops)

* Removed bugs (notably some incorrect types, off-by-one indices, and
incorrect format statements).

* Removed redundant phi and theta routines whose functionality was already
done by statement functions.

* The updated example now produces identical results to the equivalent C
example without any valgrind problems.  This tests the implementation of
the fortran interface wrappers for plline3, plpoin3, and plpoly3.

  plplot  examples/f77/x18f.fm4  1.3


Commit from airwin (2004-01-02 22:42 CET)
------------------

* Style changes (comments, indentation, do loops).

* Make this fortran "chart recorder example" work for first time.  There are
some inevitable differences relative to the C version.

  . Used g77 (and solaris fortran and ?) library rand function to generated
    random numbers.  Users will probably have to substitute some other
    library call for random numbers for other compilers.  Note the numbers
    returned by rand are different from those of the C Library routine
    drand48 so the interactive results look different (but still it looks
    like a chart recorder which is cool.)

  . plsError not part of the PLplot common API so bypassed it and let PLplot
    do its own error handling.

  . Dropped sleep interval from loop.  10 ms is about right, but the g77
    sleep routine only has a resolution of 1 second (which is like watching
    paint dry).  Actually eliminating the loop delay altogether still makes
    a good-looking "chart-recorder" example (at least on my 600MHz machine).

  plplot  examples/f77/x17f.fm4  1.3


Commit from airwin (2004-01-02 22:25 CET)
------------------

Implement fortran interface wrapper for plstripc.

  plplot  bindings/f77/scstubs.c    1.31
  plplot  bindings/f77/sfstubs.fm4  1.10


Commit from airwin (2004-01-02 22:24 CET)
------------------

Expand number of strings that can be simultanously handled to 9 (fortran
plstripc needs this).

  plplot  bindings/f77/sfstubs.h  1.2


Commit from airwin (2004-01-02 18:54 CET)
------------------

Change docmentation of id parameter of plstripc: input ==> output.

  plplot  doc/docbook/src/api.xml  1.61


Commit from rlaboiss (2004-01-02 17:22 CET)
--------------------

Move back to the non-Automake method for generating the
examples/*/Makefile.examples.

configure option --with-pkg-config is an opt-in now and defaults to "no".

  plplot  configure.ac                       1.132
+ plplot  examples/c/Makefile.examples.in    1.13
- plplot  examples/c/Makefile.examples.am    1.2
+ plplot  examples/c++/Makefile.examples.in  1.12

+ plplot  examples/f77/Makefile.examples.in  1.12
- plplot  examples/f77/Makefile.examples.am  1.2


Commit from airwin (2004-01-02 04:35 CET)
------------------

Fix for -dev tk on Linux.  src/plctrl.c requires BIN_DIR to be set to the
hard install path in order for -dev tk to find things.  To accomplish this
make the following fix:

-AC_DEFINE_UNQUOTED(BIN_DIR, "$BIN_DIR",
+AC_DEFINE_UNQUOTED(BIN_DIR, "`eval eval echo $BIN_DIR`",

This follows what was done for most (not all) other _DIR variables. I could
find no other use of BIN_DIR in the build tree other than above so I think
this is okay.

Nevertheless, it is a tentative fix because I have spot-rezoned what Rafael
has done recently for his massive changes of all the _DIR variables, and he
may have had something else in mind.

  plplot  configure.ac  1.131


Commit from rlaboiss (2004-01-01 22:33 CET)
--------------------

In src/plctrl.c, implemented plsabort, that does for plabort the same as
plsexit does for plexit (i.e., set a user abort handler).

The API sections for plsexit, plabort, and plsabort have been added to
doc/docbook/src/api-c.xml.  The plexit section was updated, since the
description of plsexit was not accurate.

  plplot  include/plplot.h                  1.146
  plplot  src/plctrl.c                      1.75
  plplot  doc/docbook/src/api-c.xml         1.8
  plplot  doc/docbook/src/plplotdoc.xml.in  1.31


Commit from airwin (2004-01-01 21:19 CET)
------------------

Greatly modified the 16th fortran example (the old version has been kept as
x16af.fm4) to mimic equivalent C example results exactly.  This tests the
implementation of the new fortran interface (PLSHADES0, PLSHADES1, and
PLSHADES2) to plshades.

  plplot  examples/f77/x16f.fm4  1.8


Commit from airwin (2004-01-01 21:14 CET)
------------------

Implement fortran PLSHADE API (in analogy with fortran PLCONT) and
PLSHADES0, PLSHADES1, PLSHADES2, and PLSHADES.

  plplot  bindings/f77/plstubs.h    1.31
  plplot  bindings/f77/sccont.c     1.7
  plplot  bindings/f77/sfstubs.fm4  1.9


Commit from airwin (2004-01-01 21:06 CET)
------------------

Fix bugs in handling transformations of zero-length or completely blank
character strings.

  plplot  bindings/f77/strutil.f  1.4


Commit from rlaboiss (2004-01-01 19:18 CET)
--------------------

Reintroduced AC_F77_LIBRARY_LDFLAGS, because the linking error that I was
observing with plplot_libtool was actually a bug in Debian package g77-3.3.

  plplot  configure.ac  1.130


Commit from rlaboiss (2004-01-01 19:17 CET)
--------------------

  * debian/control: Added pkg-config to build-dependencies and to
    libplplot-dev Recommends:.

  plplot  debian/changelog  1.62
  plplot  debian/control    1.41


Commit from rlaboiss (2004-01-01 19:06 CET)
--------------------

Use pkg-config in examples/*/Makefile.examples when appropriate

   - Makefile.examples are now under Automake control.  This means that
     Makefile.examples.in are removed from the CVS repository and replaced
     by Makefile.examples.am.  The Makefile.examples.in are automatically
     generated by bootstrap.sh (no change to the script was needed for
     that).

   - In the Makefile.examples.am, the rule to build the examples look
     like this:

     .c$(EXEEXT):
     if have_pkg_config
             $(CC) $< -o $@ `pkg-config --cflags --libs plplot$(LIB_TAG)`
     else
             plplot_libtool --mode=link $(CC) $(CFLAGS) $< $(INCLUDEANDLIB) -o
+$@
     endif

   - The AM_CONDITIONAL have_pkg_config is exercised in configure.ac and
     will be "true" when the pkg-config program is found in the system.
     Also, there is a configure option --without-pkg-config (or
     --with-pkg-config=no) that will disable the use of pkg-config and
     fallback to plplot_libtool.

  plplot  configure.ac                       1.129
- plplot  examples/c/Makefile.examples.in    1.12
+ plplot  examples/c/Makefile.examples.am    1.1
+ plplot  examples/c++/Makefile.examples.am  1.1
- plplot  examples/c++/Makefile.examples.in  1.11
+ plplot  examples/f77/Makefile.examples.am  1.1
- plplot  examples/f77/Makefile.examples.in  1.11


Commit from airwin (2004-01-01 18:07 CET)
------------------

Change the logic of the previous bug fix so the test for what to do with the
plcont case is now identical to the test (pltr && pltr_data) done inside
plshade.

  plplot  src/plshade.c  1.24


Commit from airwin (2004-01-01 01:41 CET)
------------------

Fixed subtle bug for the corner case when pltr == NULL AND contouring is
wanted.  In this case, plshades is supposed to have the same interpretation
as plshade, that is if pltr == NULL then transform the x and y index ranges
to the ranges xmin to xmax, and ymin to ymax.  Normally, that transformation
was accomplished by simply passing on pltr to plshade to deal with using the
correct transformation.  But a complication arose for pltr == NULL when
plshades was asked to also invoke plcont after its invocations of plshade.
The plcont interpretation of pltr is different, and in fact it must be
specified so the NULL was causing a segfault.  The solution for the case of
pltr == NULL and contouring is to generate the appropriate x and y grids
ranging from xmin to xmax and ymin to ymax on the fly and set up the
invocation of plcont from plshades appropriately.

I copied the ideas for the necessary memory management from other plplot code
and tested the result with valgrind to make sure no memory management issues
have been introduced by this bug fix.

  plplot  src/plshade.c  1.23

[Plplot-general] [Plplot-devel] New CVS distribution tarball available

[Rafael L. <rla...@us...>]

A new CVS snapshot distribution tarball for PLplot is available at the usual
place:

    http://people.debian.org/~rafael/plplot.html

The tarball name is plplot-5.2.1.cvs.20031231.tar.gz.  This tarball includes
several fixes of broken things since the last released tarball.  See the 
ChangeLog below for details.

This tarball can be considered as a release candidate for the next version
of PLplot (to be hopefully released in January 2004).  Please, test and
report.

This is the last cvs tarball release of 2003.  Have a Happy New Year and
thanks to all people who are helping us to put the next release out of the
door.

Commit from rlaboiss (2003-12-31 14:14 CET)
--------------------

Commented out the call to AC_F77_LIBRARY_LDFLAGS, because it seems useless,
besides triggering an error when using plplot_libtool to build the F77
examples.

  plplot  configure.ac  1.128


Commit from rlaboiss (2003-12-31 02:46 CET)
--------------------


Sane behavior of TCL_DIR, LIB_DIR, and BIN_DIR.

  TCL_DIR: Made coherent the AC_SUSTitution for bindings/{tcl,tk}/Makefile.am
    and the #define for bindings/tcl/tclAPI.c.  They both are prefixed by
    $datadir now.

  LIB_DIR & BIN_DIR: Made those Autotools-friendly.  They are now defined as
    $libdir and $bindir, respectively.  Besides this, LIB_DIR does not need
    to be AC_DEFINEd and BIN_DIR does not need to be AC_SUBSTituted, so
    removed those calls.

  plplot  configure.ac              1.127

Commit from rlaboiss (2003-12-31 02:34 CET)
--------------------

Call return after two calls to plabort in function plInitDispatchTable. This
prevents a gratuitous segmentation fault when the drivers library cannot be
opened.

  plplot  src/plcore.c  1.122


Commit from rlaboiss (2003-12-30 22:52 CET)
--------------------

Quoted definition of DOC_DIR, such that '${datadir}'is propagated into the
Makefiles.  This allows specification of prefix at make run, like "make
prefix=/some/dir", as David Schleef suggested some time ago in plplot-devel.
Also changed the name of the variable from DOCDIR to DOC_DIR, for
consistency with the other *_DIR variables.

Commit from airwin (2003-12-30 19:48 CET)
------------------

Make the actual leading dimension larger than the defined leading dimension
of the z matrix.  The results were the same (as the equivalent C example)
which tests both the leading dimension functionality of the fortran
interface to the 3D functions and the latest commit of sc3d.c which now
implements that fortran interface to the 3D functions using plAlloc2dGrid
and plFree2dGrid rather than in-line code.

  plplot  examples/f77/x08f.fm4  1.9


Commit from airwin (2003-12-30 19:42 CET)
------------------

Use plAlloc2dGrid and plFree2dGrid rather than in-line code to create
a vectored array from the transpose of the fortran matrix.

  plplot  bindings/f77/sc3d.c  1.12


Commit from rlaboiss (2003-12-30 19:40 CET)
--------------------

Sane treatment of DATA_DIR and DRV_DIR

The variables/#defines DATA_DIR and DRV_DIR are treated now in a more
coherent and Autotools-friendly way.  The main changes regard:

    - Use of $libdir and $datadir as prefixes of DRV_DIR and DATA_DIR,
      respectively, in configure.ac.  This allows users to easily override
      the installation locations when running configure (options --libdir
      and --datadir).  The environment variables DATA_DIR and DRV_DIR are
      still honored.

    - DRV_DIR is an absolute path now, not relative to DATA_DIR as before.
      Besides it being cleaner and more intuitive, the new design allows
      better compliance with the FHS.  Indeed, architecture-independent
      files (like the font amd map files, as weel as examples and the Tcl
      stuff) go by default in $prefix/share, while driver module files
      (which are architecture-dependent) go in $prefix/lib.

As regards final results, the only difference with the previous situation is
that the *.fnt and *.map files are installed now in plplot<version>/ instead
of plplot<version>/data.  I did not try to keep the previous situation
because it would imply in the definition of a new variable/#define.
However, if the other developers have really strong arguments in favor of
it, I will implement that.

Drop Octave-2.0.x compatibility at the script level. The PLplot library bindings are still Octave-2.0.x compatible.

Octave-2.0.x is very old, and even the Octave developper recomends using Octave-2.1.50.
The script components of the Octave bindings now require Octave-2.1.50 or greater;
however, the PLplot library bindings are still compatible with any Octave version.

------------------

Embedded underscore fix.  For g77 all names by default that originally have
an underscore in them have two underscores appended rather than the usual
one.  hello ==> hello_ while hello_world ==> hello_world__ . Therefore, I
have appended an additional underscore to the three plplot function names
(pl_setcontlabelformat, pl_setcontlabelparam, and plcalc_world) that have an
underscore embedded, and this seems to build and execute fine with g77,
while the build fails on g77 without this fix.  We may have to do something
additional for some platforms/compilers to get them to work with this g77
default naming convention as well, but apparently, the reason this is the
default for g77 is this is the behaviour of many Unix fortran compilers
(according to info g77).

Change 15th example to (a) make it work for the first time (there were
incorrect arguments in some cases, and the 15th example uses more than 3
colours in cmap0 so that is why plscmap0n(3) is commented out in the C
example case and is now dropped altogether in this fortran example case) and
(b) obtain exact agreement with file results from the corresponding C
example. This agreement confirms that the fortran interface plshade0
function is implemented correctly.

Re: [Plplot-general] about plotting

[Michel P. <Mic...@en...>]

From=20my point of view the answer is yes. I have used it for simulations o=
f
nonlinear excitations in lattices, and to display in "real time" the
formation of DNA hairpins in simple models of the molecule (many coupled
nonlinear equations). Of course it slows down a simulation but for us it
is worth it. Seeing the dynamics as it develops is often very useful to
understand what is going on.

[Plplot-general] about plotting

[Lam Wa K. <rex...@ho...>]

Hi all,
  I wonder if pplot is powerful enough in realtime plotting. I am working 
for 2D simulation of nonlinear equation and there are lots of data to be 
plotted every few seconds.

[Plplot-general] compile pplot on MsWin (non-VC user)

[Lam Wa K. <rex...@ho...>]

Hi there,
  I am using c++ on MsWin. However, I am not using VC but gcc (which 
enclosed in Devcpp). I
am trying to compile the necessary source files into a lib. However,
there are lots of files and I have no idea which one should be inclued.
Would you please help me?

Any reply will be appreciated.

[Plplot-general] New CVS distribution tarball available

[Rafael L. <rla...@us...>]

A new CVS snapshot distribution tarball for PLplot is available at the usual
place:

    http://people.debian.org/~rafael/plplot.html

The tarball name is plplot-5.2.1.cvs.20031228.tar.gz.  This tarball includes
the latest changes in the Fortran 77 configuration settings and, hopefully,
will improve the building on the Mac OS X system.  The changelog entries
since the last CVS tarball are included below.

This tarball can be considered as a release candidate for the next version
of PLplot.  Please, test and report.

Yes, that works (tested with latest cvs release)! But it only works if 
plplot gets installed into /usr/local/. My goal is to create a plplot 
package for the fink project, which is a debian-type package manager 
for Mac OS X. Fink installs everything into a special dedicated 
directory /sw. If I run the examples from /sw/share/plplot/examples, I 
get an error about fonts:

*** PLPLOT ERROR ***
Unable to open or allocate memory for font file
Program aborted.


Does plplot install its own fonts (and where)?

[Plplot-general] New Mandrake RPMS available

[Brian D. W. <bdw...@ph...>]

Hi Folks,
	I've updated the previous version of my Mandrake 9.2
spec file (attached) to work with Rafael's latest 12/27 CVS tarball. This 
time no patches are needed :) (as long as linuxvga is disabled). 
The file installation locations work fine using DESTDIR during the 
packaging "make install" step.
The rpm list is 

libplplot9-5.2.1.cvs.20031227-1mdk.i586.rpm
libplplot9-devel-5.2.1.cvs.20031227-1mdk.i586.rpm
libplplot9-driver-gd-5.2.1.cvs.20031227-1mdk.i586.rpm
libplplot9-driver-gnome-5.2.1.cvs.20031227-1mdk.i586.rpm
libplplot9-drivers-5.2.1.cvs.20031227-1mdk.i586.rpm
libplplot9-java-5.2.1.cvs.20031227-1mdk.i586.rpm
libplplot9-static-devel-5.2.1.cvs.20031227-1mdk.i586.rpm
libplplot9-tcltk-5.2.1.cvs.20031227-1mdk.i586.rpm
libplplot9-tcltk-devel-5.2.1.cvs.20031227-1mdk.i586.rpm
libplplot9-tcltk-static-devel-5.2.1.cvs.20031227-1mdk.i586.rpm
libplplot-octave-5.2.1.cvs.20031227-1mdk.i586.rpm
libplplot-python-5.2.1.cvs.20031227-1mdk.i586.rpm
plplot-5.2.1.cvs.20031227-1mdk.i586.rpm
plplot-tcltk-5.2.1.cvs.20031227-1mdk.i586.rpm

I'd appreciate any more comments about the files distribution, package 
naming, etc. I've tried to use Mandrake's conventions as per their RPM-HOWTO.
I suspect the same spec file would work for other RPM based distributions 
with minor modifications. 

For now the binary rpms can be downloaded by ftp from:
ftp://keck.ucsf.edu/pub/urpmi/Mandrake/9.2/RPMS

or using urpmi with the medium:
urpmi.addmedia bdw_contrib_i586_9.2
ftp://keck.ucsf.edu/pub/urpmi/Mandrake/9.2/RPMS with ./hdlist.cz

The source rpm is in ftp://keck.ucsf.edu/pub/urpmi/Mandrake/9.2/SRPMS

After getting the blessing of the plplot-developers I'd like to submit 
this to Mandrake's Cooker.

Cheers,
Brian

P.S. If you'd like to rebuild the rpms, I've
packaged libcd (cgmdraw) and repackaged tcl/tk/itcl
from Mandrake to add the needed development files.
You can get these from the above ftp/urpmi site as

cd-1.3-1mdk.i586.rpm
libcd1-devel-1.3-1mdk.i586.rpm
expect-8.4.2-3mdk.i586.rpm
itcl-8.4.2-3mdk.i586.rpm
tcl-8.4.2-3mdk.i586.rpm
tcllib-8.4.2-3mdk.i586.rpm
tclx-8.4.2-3mdk.i586.rpm

This is a very strange bug, indeed, and I have no clue about its origin.  It
is perhaps a libtool bug that is triggered on the Mac OS X system. Could you
please run:

    make 2>&1 > ../build.log

and send the resulting build.log to me?

Have you tried to configure the 5.2.1 release with --enable-dyndrivers?

When using ./configure without disabeling the dyndrivers, the 
compilation eventually halts:

...
./get-drv-info `echo hpgl.la | sed 's/.la//'` > hpgl.rc

I've seen that problem too, even with today's snapshot. Here's the 
output:

It goes away if I remove the "--disable-dyndrivers" argument. Then the

Those on plplot_devel are already aware of the fortran status, but I should
summarize it here as well:

I have recently done a lot of work to extend the fortran interface (29
additional functions now available) and examples for PLplot.  The changed
interface and examples build on Linux with the default double precision, and
the result is the first 7 standard examples for fortran give near identical
results to the corresponding C examples.  But I plan considerable additional
work in the next week or so to extend both the fortran interface and
examples to the point where they can mimic the complete standard set of C
(and tcl, python, java, octave, and yorick [yplot]) examples. Also, I plan
to make fortran work again with the single-precision form of the PLplot
library (i.e., the --without-double option), and there is still some
configuration work to do to help fortran work on other platforms than Linux.

So _from the fortran perspective_, this particular snapshot works for
Linux, but I doubt it will work on other platforms yet, and even on Linux it
is a work in progress.

In contrast to fortran, the non-fortran parts of PLplot should be fine
cross-platform except possibly for a configure issue one Mac OS X 10.3 user
has reported which still needs confirmation.  Also, this cvs version is
quite stable for developers and includes many bug fixes relative to the
5.2.1 version.  So I agree with Rafael that for the non-fortran parts this
cvs snapshot is of near release-candidate quality.

Also, I want to publically thank Rafael for his work on the PDL examples and
in generating this tarball after a long hiatus caused by the debian.org
intrusion.  It is great to see the plplot cvs snapshot tarballs back at
http://people.debian.org/~rafael/plplot.html!

Here is the detailed cookbook.  After make install, do the following to
build the examples:

cd /tmp (or any other directory accessible to you as an ordinary user)

copy the installed examples tree (the trailing period is important):

cp -a $prefix/lib/plplot$version/examples .

go into the C examples directory and build those examples:

cd examples/c
make x01c  (or drop the x01c from the command to build all C examples)

Then in that same directory to execute the built example:

./x01c -dev psc -o temp.ps

which creates the result file temp.ps containing the coloured postscript
plot of our example 1.

BTW, you could help us out a lot (assuming you have MacOS X 10.3) to try the
latest cvs snapshot version Rafael just announced.  We need confirmation of
a report from one user that he could not even configure the cvs version of
Plplot with 10.3.  Please use an install tree (e.g.,
--prefix=/tmp/plplot_cvs) completely independent of your 5.2.1 install
tree/.  You will have to put $prefix/bin first on your path so that e.g.,

which plplot_libtool

gives you the correct version from your cvs snapshot plplot build and install.

[Plplot-general] New CVS distribution available

[Rafael L. <rla...@us...>]

A new CVS snapshot distribution tarball for PLplot is available at the usual
place:

    http://people.debian.org/~rafael/plplot.html

The tarball name is plplot-5.2.1.cvs.20031226.tar.gz. It was generated in a
Debian unstable system with the following versions of the GNU autotools:

    Autoconf  2.58
    Automake  1.7.9
     Libtool  1.5.0a

Several changes and bug fixes since the last cvs distribution tarball
(tagged 20031030) are included, but I think that the two most important
improvements are the extension of the Fortran bindings API (done by Alan),
and the inclusion of demos for the Perl/PDL bindings.

You will find below the changelog of the recent changes in CVS, generated
with the cvsreport utility.

Please, test and report.  As with the previous ones, this tarball can be
considered as a "pre-candidate-release" for the next official version of
PLplot.  I am looking forward to strengthening our occupation in different
niches like Fortran and Perl/PDL bindings (I hope to catch up with the
upcoming PDL 2.4.1 release), as well as among users of Mac OS X.

--------------------

Disabled inclusion of drivers/*.rc in the distribution tarball

Revert the previous changes regarding includion of the drivers/*.rc files
into the tarball, because a .rc file depend on the .la file, which gets
built with "make" by the user.  The result is that the *.rc and get-drv-info
are built anyway.

I will think later on a better way to include the *.rc files in the tarball.

Commit from rlaboiss (2003-12-26 16:06 CET)
--------------------

Modernized some Autotools constructs

The following old-style calls in configure.ac:

    AC_INIT(src/plcore.c)
    AM_INIT_AUTOMAKE(plplot, 5.2.1)

have been modernized to:

    AC_INIT(plplot, 5.2.1, plp...@li...)
    AC_CONFIG_SRCDIR(src/plcore.c)
    AM_INIT_AUTOMAKE

(see "info autoconf" and "info automake" for details).

The three scripts that parsed configure.ac and relied on the old-style call
of AM_INIT_AUTOMAKE have been changed accordingly.

  plplot  configure.ac                    1.118
  plplot  bootstrap.sh                    1.26
  plplot  debian/get-upstream-version.pl  1.2
  plplot  scripts/check-tarball-cvs.sh    1.3


Commit from rlaboiss (2003-12-26 15:31 CET)
--------------------

Disabled generation of reconfig script by configure

As per our discussion in plplot-devel in September 2003 (and since Maurice
agreed), the section in configure.ac responsible for the generation of the
reconfig script is removed.  The command "./config.status --recheck" has the
same effect (i.e. calling configure with the previously specified options).

In order to keep the functionality for the fingers too used to type
"./reconfig", a one-line shell script called reconfig has been added to the
repository.

Also, added reconfig to the EXTRA_DIST variable in the top-dir Makefile.am,
such that the script gets included into the distribution tarball.

  plplot  configure.ac  1.117
+ plplot  reconfig      1.1
  plplot  Makefile.am   1.30


Commit from rlaboiss (2003-12-26 15:14 CET)
--------------------

Include most drivers/*.rc files in the distribution tarball

The goal of this change is to avoid the building of the drivers/*.rc files
by the users by including them into the distribution tarball.  This also
avoids the building of the get-drv-info utility when running "make" from the
tarball.

The price paid for this improvement on the user's side is that "make" is
needed before "make dist" (see scripts/make-cvs-tarball.sh). This happens
because get-drv-info needs libplplot, which needs libcsirocsa and libcsironn
in turn.  Also, libltdl needs to be built.

Since this change only affects the tarball construction and since the price
paid is too small compared with the gain obtained, I decided to implement
the new behavior. If anybody objects, please let us discuss in plplot-devel.

  plplot  scripts/make-cvs-tarball.sh  1.9
  plplot  drivers/Makefile.am          1.32


Commit from rlaboiss (2003-12-26 12:58 CET)
--------------------

Fixed debug and error messages.

In function plOpenFile, the message "Opened <filename>" is sent now through
pldebug.  This means that it will not spuriously appear on stderr anymore,
but will be issued when option -debug is specified.  Also, the message
"Can't open <filename>" is sent now to stderr instead of stdout.

In function plLibOpenPdfstr, two calls to pldebug are fixed now (called with
two argments instead of three).

File device result still disagree with corresponding C example.  java

Add the following API wrappers to the fortran interface:

PL_SETCONTLABELFORMAT
PL_SETCONTLABELPARAM
PLCALC_WORLD
PLCLEAR
PLCPSTRM
PLFILL3
PLGCOL0
PLGCOLBG
PLGCOMPRESSION
PLGDIDEV
PLGDIORI
PLGDIPLT
PLGRIDDATA
PLGVPD

PLSCMAP1N
PLSCOMPRESSION
PLSDIDEV
PLSDIMAP
PLSDIORI
PLSDIPLT
PLSDIPLZ
PLSMEM
PLSTRIPA
PLSTRIPD
PLXORMOD

All of these new wrappers build without problems, but there are no examples
to run-time test them yet.  Also there still remains work to do
on the PLMESHC, PLOT3DC, PLSHADE1, PLSHADES, PLSURF3D, and PLSTRIPC wrappers
to implement all the common API.

------------------

* Replace file designed to be processed by m4 by result of m4 processing of
that file using double precision.  Fortran passes everything by reference,
and there is no actual numerical computation or constants in this fortran
source.  Thus, I believe the double precision is only technical in this case
and needs no further processing in the single-precision case.

x19f excluded from these Makefiles because this example invokes plmap and

Convert all floating-point constants in fortran examples to standard
double-precision form.

e.g., .3 ==> 0.3d0.

Also, convert ugly dble (0.3), etc.  in argument lists to 0.3d0.

This was all done by a fairly well tested sed script that I have developed

Examples 3, 9, 11, and 13 gave slightly different (but still visually
acceptable) answers as a result.

--------------------

I just noticed that the Octave function octave_config_info accepts an
argument.  This slightly simplifies the OCTAVE_CONFIG_INFO macro.  This
change was tested only with Octave 2.1.50.  Hopefully it will work with any
version of Octave supported by PLplot.

Revamped ToDo list

Reorganization of this ToDo list, separating task that are already completed
or abandoned from those issues that are still open.  Also, added an item
about the implementation of the --enable-strip-libraries option of configure.

-----------------

-Make default visual the default, use "-drvopt defvis=0" to not use the default visual.
-Add "usepth" driver specific option; enable pthreads by default, use "-drvopt usepth=0"
 to not use pthreads to redisplay the plot.
-Fix subtle bug when using pthreads with two or more plot windows; when resizing one of them
 the resize/replot was directed to the plot window on the current stream.
