[Plplot-general] plplot-5.2.0

[Valerij P. <vp...@ir...>]

I've got the announcement about plplot-5.2.0 release. First of all, many 
thanks to maintainers for such a nice software. 
 May I ask a question? Does the tar file of release differ from the today's 
cvs tree? The problem is that I'm not able to build the plplot from cvs.
First I tried through ./bootstrap and have  the following warnings
""ls: libltdl/*: No such file or directory
WARNING: Using auxiliary files such as `acconfig.h', `config.h.bot'
WARNING: and `config.h.top', to define templates for `config.h.in'
WARNING: is deprecated and discouraged.

WARNING: Using the third argument of `AC_DEFINE' and
WARNING: `AC_DEFINE_UNQUOTED' allows to define a template without
WARNING: `acconfig.h':

WARNING:   AC_DEFINE([NEED_MAIN], 1,
WARNING:             [Define if a function `main' is needed.])

WARNING: More sophisticated templates can also be produced, see the
WARNING: documentation.""

After ./configure and make I've get
""Making all in libltdl
make[1]: Entering directory `/home/soft/RPM/BUILD/plplot-5.2.0/libltdl'
make[1]: *** No rule to make target `all'.  Stop.
make[1]: Leaving directory `/home/soft/RPM/BUILD/plplot-5.2.0/libltdl'
make: *** [all-recursive] Error 1""
Next I tried to cook a different configure script in dir cf via typing 
autoconf. After reconfiguration the buildings stops with the following errors
"gcc -c          -O    -I. -MD -MF .d.pdfutils -MP -c pdfutils.c -o pdfutils.o
pdfutils.c:30:21: plplotP.h: No such file or directory
pdfutils.c:33: parse error before '*' token
pdfutils.c:57: parse error before '*' token
pdfutils.c: In function `pdf_fopen':
pdfutils.c:60: `PDFstrm' undeclared (first use in this function)
etc"
The problem here that configure script does not make the rigth path to the 
include files. I'm working with ALTLinux distribution, autoconf-2.2.57, 
gcc-3.2.1, kernel-2.4.20. I have no such a problem with  5.1.0 version. 

rgds,

[Plplot-general] PLplot-5.2.0 has just been released!

[Alan W. I. <ir...@be...>]

This is a quick announcement of the PLplot-5.2.0 release that has just
occurred. The official announcement will come later this week when I will
have more time to write it. Find the new release at
http://sourceforge.net/project/showfiles.php?group_id=2915.

There is a PLplot-5.2.0 tarball as well as RH7.3 source and binary rpms for
PLplot-5.2.0 there.

There have been paradigm shifts in our library organization and in our
Linux/Unix configuration system which is now generated using autotools. So
please hammer on PLplot-5.2.0 for as many Unix/Linux platforms as you have
access to with the usual configure; make; make install.  The best way
to test is to cd $prefix/lib/plplot5.2.0/examples, execute make in each
of the c, c++, f77, and tk subdirectories, then execute plplot-test.sh.

"Works for me!" type reports with a clear description of your platform are
most welcome.  Of course, if you have problems please report back to
plplot-devel with the detailed results of configure, make, and make install
commands (and of course the description of your platform), and we will try
to sort out what the problem is.  There are bound to be some teething
troubles with paradigm shifts like these, but PLplot-5.2.0 has been
extensively tested on Linux systems and works well for them. Configuration
systems built with autotools are designed to be platform-neutral so there is
also good potential to be able to build and run PLplot-5.2.0 on a wide
variety of other Unix platforms as well.  So try it and see!

To motivate you to try this new release, I should mention that the python
and java interfaces to PLplot are now much more complete (thanks to swig).
Also have a look at our new screenshots on
http://plplot.sourceforge.net/examples/index.html (especially examples 8 and
11) to see what treats are in store for you.

I would like to take this opportunity to thank all our developers for their
effort over the last year.  That effort has just culminated in PLplot-5.2.0
which is the best version yet!

[Plplot-general] Re: [Plplot-devel] How to Build PLplot to use with Tcl-tk

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

Sorry, my last msg was nonsense.  You will need to rebuild the Plplotter
package for tcl-tk, using the makefile.vc in sys/win-tk.  You will also
need to edit the plDevs.h file in that directory to enable the drivers you
want (jpeg), and you will need to make sure any additional libraries and
header files needed by that driver are accessible.  Only then can you do
what I suggested in my previous email.

[NB: I just committed a fixed makefile.vc to cvs]

cheers,

[Plplot-general] Re: [Plplot-devel] How to Build PLplot to use with Tcl-tk

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

I believe that version already comes with jpeg support in its 'gd'
library, and (assuming you downloaded the binary from my web page) it is
compiled in.  You can test this with:

package require Plplotter
plframe .p
pack .p
.p cmd plsdev jpeg

which should not throw an error.  Assuming this is the case, you can use
whatever standard Plplot functions you like, or edit the .tcl scripts
which come with Plplot to provide a more seamless menu-based saving of
jpegs.

cheers,

[Plplot-general] How to Build PLplot to use with Tcl-tk

[Pankaj L. <pa...@da...>]

Hi,

I am using PLplot 5.1.0 along with tcl-tk on windows NT. I want PLplot to
support jpeg format as one of its File output device format as mentioned in the
user document.

I tried my luck by browsing on plplot mailing list to figure out how can this be
done but without much success?

Can anyone help me with the procedure to rebuild Plplot on windows NT? I would
like to use Plplot with JPEG format support with tcl-tk as development language.

Thanks.

Pankaj.

[Plplot-general] To obtain Co-ordiantes

[Rayal <ra...@da...>]

Hi

I could obtain the world co-ordinates if  I use plframe . However if  I =
use Plplotwin object,
 I am not able to obtain these values,  the reason is that I am not able =
to correctly bind=20
the Plplotwin object.
=20
for example, in this code:          =20
=20
bind .p <Button-1> {=20
   get_coords %x %y=20
}

proc get_coords {g h} {
   =20
   update
    puts "world coordinates: [.p report wc $g $h]"
}



If .p is a plframe object it works but not if it is a Plplotwin object. =
The "report" option is  giving the=20
'bad option' error. Could you please suggest any work around for this.

Re: [Plplot-general] How this can be achived ?

[Piyush L. <pi...@da...>]

Hi Joao,

Thanks a lot for the reply.

I have successfully built the example x17c( x17c.cpp) and studied its
behavior. In this sample, when the values of plot points crosses Ymax
and/or Xmax,  the plots are shrinked to fit in the existing viewport.

My requirement is, When the plot points crosses YMax and or XMax values.
Instead of shrinking the plot to accommodate the new points in the same
viewport, I would like to add a scroll bar, using which the user can scroll
the view. This would enable the user to see previous points which are gone
out of the view.

Can share any idea how this can be done ?

Thanks for any thoughts on this.

regards,
Piyush L.

Just plotting the data again, specifying the new limits? Or is a strip-ch=

plotter what you want? see the x17c c example.

[Plplot-general] How this can be achived ?

[Piyush L. <pi...@da...>]

Hi,

I am using Plplot 5.1.0 and tcl/tk 8.4 on Windows NT. I am working on a =
project
that requires real time data plotting. My requirement is that the plot =
should be
a strip chart. All the new points should be plot on the right hand side =
with
graph sliding to left, making room for new points. The User can view the =
full
plot using the scroll bars.

When we create the Plplotwin object first we need to specify the =
viewport and
then window. In this we specify the boundary of the graph to be plotted, =
and
there by restricting the size of the plot to be plotted .

Is there any way by which we can eliminate the need of the upper limit =
of the
boundary ( xmax, ymax ) ? Is than any work around which help me to make
continuos plot ?

Does anybody has any idea how this can be done in plplot.?

Thanks for any help.

Re: [Plplot-general] scrolling in Plplotwin object

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

I believe the 'Plplotwin' megawidget already has scrollbar and scrolling
functionality which is automatically activated when needed --- when you
zoom into the widget (e.g. press 'z' and zoom in, or this can be done
manually).

| Yes, I know, I have compiled gcc-3.2.1 myself and plplot_octave (not

|
| does not compile. It looks like that  class vector string is missing:

The problem has a simple solution, just type the following in the plplot=20
'tmp' directory when "make" gives the error:

sed 's/ string / std::string /' plplot_octave.cc > po
mv po plplot_octave.cc

Don't forget the spaces in the sed command, just copy/paste the above
and then resume the make. I have done it with the current cvs tree and=20
plplot_octave compiled and runs OK.

However, you will find that plplot_octave gives some warnings with=20
octave-2.1.40.

plplot_octave.cc $(OCTAVE_LIBS)

You have to watch the output of a plain make in order to get=20
$(OCTAVE_LIBS), or you can browse the Makefile.

I confirm the problem. I built octave-2.1.39  with gcc-3.2 and options  
--enable-dl --enable-shared. When I tried to build plplot with octave by 
using gcc-3.2 the building breaks at compiling   plplot_octave.cc. Then
I made reconfigure with  "CXX=g++-2.95.3 ./configure ......".
 
Well, the compiling was ok after this except I cannot use this built to make 
rpm because of wrong parameters in  RPATH variable  (it was a wrong path 
which referee to the build dir and not to the path where octave module to be 
installed).

Yes, I know, I have compiled gcc-3.2.1 myself and plplot_octave (not plpl=
ot)=20
does not compile. It looks like that  class vector string is missing:

> more /usr/include/g++/string
    // Main header for the -*- C++ -*- string classes.

    #ifndef __STRING__
    #define __STRING__

    #include <std/bastring.h>

    extern "C++" {
    typedef basic_string <char> string;
    // typedef basic_string <wchar_t> wstring;
    } // extern "C++"

    #endif

> rpm -qf /usr/include/g++/string
    libgpp-2.95.3-216

So, the new gcc-3.2.1 does not has libg++, that is where "string" comes f=
rom.

I will correct this in the future, but for now you can only use gcc-2.95.=
x.=20
(or compile libg++ if you find it -- it's now kind of obsolete, I think).=
 I'm=20
pretty sure that octave 2.1.40 compiles with gcc-2.95.x, so it's your las=
t=20
resort.

Joao

Nope. I only tried Octave-2.1.36 and gcc-2.95.3.

I know that Octave has suffered some significative changes since version=20
2.1.38. Do you have to use 2.1.40? If you could try 2.1.36 with gcc-3.2 i=
t=20

[Plplot-general] problem compiling plplot with octave

[David A. <arm...@SE...>]

I have a (modified) Red Hat 7.3 system I am trying to install Plplot on. 
 I have Octave 2.1.40 and have compiled it with --enable-dl and 
--enable-shared.  I have configured PlPlot with --eanble-octave.  When I 
try to compile Plplot it generates many errors in the plplot_octave.cc 
file.  Below is the beginning of the error message stream.  I am using 
gcc 3.2 and I have installed matwrap.  Anyone have any idea what is 
going on here?

Dave Armstrong

So now it does not complain about not founding gd.h. We are near..
Now it looks like 'configure' can't find the gd library, libgd.so.

=46rom your words it looks like you only have extracted gd.h from the rpm=

(include and libraries) are needed.

Why don't you install it all? You can install it in /usr/local, as=20
'configure' search for it there, but  the "standard" place is safer.

On my system, I have the following installed:
