Hi Hans,

How did you configure the wxWidgets library? from the makefile it  
seems that you use wxX11 and maybe even the "universal" build. This is  
not recommended at all, since the wxX11 is rather not much supported,  
so it may work for you or not. In this case it seems it doesn't work  
for you. It's much better to use the wxGTK port of wxWidgets, since  
this port is actively worked on, feature complete and looks fine. Bad  
thing is, that you need the gtk libraries installed (and the gtk  
developer files on the developer machine), but this is actually always  
the case, even on KDE machines.

If you are using wxX11, and there is no problem using gtk (RHEL 4 has  
surely decent gtk support), then I would strongly suggest to use  
wxGTK. And don't use the universal build, since I also doubt if that  
works for the wxWidgets driver, at least I never have tested this.

HTH,
Werner

I also have other things now on my todo list, but some time ago I was  
interested what I could find on the internet about the Hershey fonts, and  
I found some links which may be helpful:

* http://www.codeproject.com/KB/GDI/hersheyfont.aspx
* http://emergent.unpythonic.net/software/hershey
* http://www.efg2.com/Lab/OtherProjects/Hershey.htm - this seems to be an  
editor, which allows to edit hershey fonts

Hi Hans:

I confirm an underscore issue on Linux.  Thanks for reporting this issue.

Here is what I found.  For -dev xwin; -dev psc -drvopt text=0; -dev png
-drvopt text=0; and -dev wxwidgets -drvopt freetype=0 the underscore is
replaced by a (very) short dash.  All those cases involve our traditional
Hershey fonts.  From this evidence I believe there is something
fundamentally wrong with those fonts for the underscore character.

One possibility was that our binary form of Hershey fonts somehow got
clobbered in the underscore position accidentally in our CVS days, in the
CVS to svn transition, or during the svn era since.  However, that turns out
not to be the case. I just (revision 9370) tweaked our build system to
optionally (by default this is turned OFF) build programmes to generate the
binary form of our Hershey fonts.  (This was an interesting historical
exercise.  I consulted the plplot-5.0.0 build directions [from our build
system from three generations ago!] to help figure out how to build those
programmes.) See fonts/README for directions on how to use our build system
to build the programmes to generate our Hershey fonts). When I ran those
programmes, the results were absolutely identical with data/plstnd5.fnt and
data/plxtnd5.fnt that were generated more than 8 years ago.

Another possibility is the directions for creating the Hershey underscore
glyph are just plain wrong. (It could be missing as well, but then I don't
think you would be seeing the short dash.) I had a look at the code in the
fonts subdirectory that generates the Hershey fonts, and it is essentially
undocumented. Therefore, it is going to take some effort to figure out, for
example, the correspondence between any given glyph (such as underscore),
and the data (pen positions I assume for drawing the glyph) that is given in
the source code.  I don't have time for such an effort (especially because
our Hershey fonts are gradually being replaced by TrueType or Type 1 fonts
for most of our devices). However, if somebody wants to make the effort to
figure out the Hershey underscore problem, I would be happy to apply the
fix.

It's actually more work than I thought, since in Windows (and maybe  
other platforms) it is not allowed that two threads use GUI objects  
(like pen, brush, etc.) since they are not thread-save. So it's not  
possible that I have a thread which just keeps the window up2date and  
so on, and the other thread plots into a bitmap (which is then copied  
into the window canvas) - this would lead to random crashes. In fact I  
would need to rewrite the driver interface, so that for the thread  
case, events are sent to the driver thread, which are then processed.  
So that main thread never touches any wxWidgets object. But this is  
much more work. Still worth to do, but nothing I could do in just some  
days.

You don't bother, it's a good thing, that someone uses plplot and

Good! I assume that you use just plain wxWidgets, without the agg

improved the font handling, looks nicer, but if it is the "basic"  
backend (in the windows title it says something like "wxWidgets PLplot

Going to PlPlot version 5.9.2 the text plotting with the WxWidgets driver on Vista is improved enormously and includes the proper plotting of the "_".

Is there a way to get the xwin driver on Linux also plot the "_" ? 

Trying to use the WxWidgets driver on Linux failed up to now with :

X Error of failed request:  BadDrawable (invalid Pixmap or Window parameter)
  Major opcode of failed request:  62 (X_CopyArea)
  Resource id in failed request:  0x0
  Serial number of failed request:  963
  Current serial number in output stream:  965

This is using the standard tests, but maybe the installation of 5.9.2 was not completely correctly for the WxWidget driver (although no errors showed up in the "cmake" and cons. "make").

Regards and thanks in advance,
Hans Rijneke

Re: [Plplot-general] Obscured plot window

[<Han...@sh...>]

Werner, Alan,

I would be very nice to have this implemented, so if it is not to much work ....

For now we will try your other mentioned solution by adding something in our event loop.

Thanks for the help,
Hans

I just had a look, it's maybe simpler as I thought, but since the
wxWidgets library supports threading on its own, I would use the
wxWidgets library for this. Still, do add this to the driver and debug
it would take some time. But it would be worth doing it.

Alan,

I did not install the wxwidgets driver on Linux, so have to first rebuild PlPlot.

But having seen the mails from Werner, I don't think  have to try.

I am now wondering if there is a thread issue for windows or for -dev
wxwidgets? To help resolve that question, are you satisfied with the
threading behaviour of -dev wxwidgets on Linux?

Re: [Plplot-general] Closing the graphics window

[Werner S. <sm...@ia...>]

Hi Hans,

sorry, took me a long time. Anyway, looking through the code I saw that
if threading is enabled only minimal events are processed. Does this
solve the close window problem?

If not, there are some solutions in the net:

http://linuxsoftware.co.nz/blog/2008/08/12/handling-window-close-in-an-x11-app
https://www.linuxquestions.org/questions/programming-9/capturing-the-window-close-event-in-x-358162/

which could be tried.

Werner

I didn't know, that the pthreads library works on Windows. But apart
from that, the wxWidgets driver does not support multi threading at the
moment - it works completely single threaded. Although it behaves a
little like a mt app, since you can see the driver drawing the plot, but
this is since the driver continuously calls the wxWidgets main loop
routine, do some drawing and leave immediately the loop again. A plend()
call will allow the wxWidgets driver to take over and do the updating of
the screen if necessary.

If you really need multi-threading this will become a little
complicated, but if e.g. you only need the plot screen being updated if
it was hidden, etc. and no menu action and so on, it's actually possible
to use an internal function of the wxWidgets driver (wxApp::Run() I
think) on a regularly basis. In case there are some Events pending (e.g.
"Screen needs repaint") then this events will be processed and if the
application goes "idle" it returns, which would allow your application
to progress. If you manage to call the driver a number of times a second
this would be as good as a multi threaded driver.

I could have a look on how the xwin driver is doing the pthread stuff
and if not that hard I could try to implement it, but that isn't
something which I can do in the next days.

Would the way I described above be a solution for you? Btw, no driver
which works on Windows has pthread support.

In Linux there is also no pthread support of the wxWidgets driver.

Before delving into the question of a background grid, are you happy with
the speed of plpoin3 for large numbers of points?  No promises, but if you
show us there is an efficiency problem for that use case, we might be
able to do something for you.

To follow what is going on with the background grid, I will walk you through
the relevant documentation and example plots.

http://plplot.sourceforge.net/docbook-manual/plplot-html-5.9.2/plpoin3.html
states plpoin3 is used in example 18.  If you check that example
(http://plplot.sourceforge.net/examples.php?demo=18), you will see it uses
the "d" option for zopt in plbox3, but from the plot results that option is
ignored.  That is consistent with
http://plplot.sourceforge.net/docbook-manual/plplot-html-5.9.2/plbox3.html
which says "d" only produces background grid lines for plot3d or plmesh.  If
you follow up by looking at
http://plplot.sourceforge.net/docbook-manual/plplot-html-5.9.2/plot3d.html
and
http://plplot.sourceforge.net/docbook-manual/plplot-html-5.9.2/plmesh.html
those routines are used in example 11. So to see what those background grid
lines look like, have a look at
http://plplot.sourceforge.net/examples.php?demo=11.

I assume the judgement call made when the background grid line logic was put
together was such grid lines would not look good for the plline3 and plpoin3
cases.  However, if you still want the grid lines, I suggest you might try a
call to plmesh or plot3d that plots no visible surface so the net visual
effect is just the grid lines.  Probably the easiest way to arrange that is
to make a minimal plmesh with the x and y points outside the plotted range
before you call plpoin3.

Hope that idea helps.

I'm not sure whether or not this is the correct way to post a question on
the plplot-general mailing list. Is I do this wrong, can anyone tell me the
correct way?

 

My Question:

I'm new to PLplot. Previously I use GNUplot but then had problem with
plotting speed when plotting too many points. Anyway, can anyone tell me if
PLplot is the right tool to go? 
 
Criteria: 
- one window with 4 subplot. Top half plot ONE 3-D plot and bottom half has
THREE 2-D plots. 
- Plot 10,000 - 20,000 points (I don't need to plot surface or lines, just
points). 
- has to be fast (My program will keep on refreshing the plot). 
 
My next question is that I tried to create a 3D plot in PLplot, but I want
to have grids on the x-z and y-z plane, just like example 11 in PLplot
website: http://plplot.sourceforge.net/examples.php?demo=11. 
My Understanding is that I need to use add a letter 'd' inside the function
plbox3(..), but the grid will only be showed after we call either
plot3d(...) or plmesh(...). 

The thing is I only want to plot a point in the 3D plane so I only use
plpoin3(...). And no grid is showed. 

Do I miss something? Is there an easy way to plot grid? Is there another way
to get what I want? 
 
thanks so much for the help. 

Re: [Plplot-general] Obscured plot window

Dear all,

This issue was nicely resolved for the xwin driver onn Linux, but now we face the similar behaviour on Window (Vista 64) using the wxwidgets driver.

PlPlot was installed with the pthreads option on (pthreads library from gnu), but as soon as you enter the obscured window again, the window title shows "not responding" and hence no refresh.

Do we forget something ?

Hans,

The xwin driver (which I assume you are using) supports automatic
updating if plplot is compiled with thread support. If you are building
the library from source then add -DHAVE_PTHREAD=ON to the cmake command
line. Provided you do have the pthread libraries installed you need to
do nothing else - xwin will automatically use it.

[Plplot-general] PLplot 5.9.2 is now available

[Hazen B. <hba...@ma...>]

Hello,

Version 5.9.2 of PLplot is now available. Major improvements since 5.9.1 
include an extended testing framework which automatically tests plotting 
results across the multiple languages supported by PLplot. There is now 
rigorous testing in place for almost all of the common API and this has 
already allowed us track down a number of bugs.

As always, (1) Please refer to our wiki for the latest build and install 
instructions 
(http://www.miscdebris.net/plplot_wiki/index.php?title=Main_Page) and 
(2) Let us know of any problems / bugs that you run across while 
installing / using PLplot.

best,
-Hazen

The octave issue I believe comes from running cmake in the source tree.
For some reason I have not got to the bottom of this does not work. You
must run cmake in a separate build tree for octave. It may be possible
to fix that, but for now a separate build tree would do. This is highly
recommended anyway - see for example the plplot wiki item on cmake.

The Java stdout issue has just been explained by inconsistent locales for
Java and C on Valery's computer.  Thanks, Valery, for sending the files to
me that made that clear.  I have just updated README.testing and

I believe that leaves only the octave issue for AltLinux.

We have sorted out the main issue which was something is wrong with libqhull
on AltLinux. This caused segfaults each time example 21 was encountered
in the testing.  -DHAVE_QHULL=OFF works around this AltLinux issue.

The remaining issues Valery has found are an agg/freetype issue, a java
stdout issue for example 31, and the octave issue.

I actually find that agg/freetype works great on Debian testing for
wxwidgets.  (Werner was not aware of this before because he does not have
ready access to Linux.) So like the libqhull case, I ascribe that problem to
AltLinux.

We are still working on figuring out the Java stdout issue and the octave
issue.

This must be a problem with the devel package, or the maintainer of  
the package didn't include the freetype support of the agg library. In  
fact I don't use the freetype functionality in the moment in the agg  
backend of the wxWidgets driver due to some unresolved problems using  
the interface, but I can't comment out everything regarding the  
freetype font interface, there is already a lot of code in the driver.

As Alan suggested, you could try to compile it yourself, or maybe  
there is an additional devel package available which adds the freetype  
font support.

I just had a look at the altlinux site (in Russian ;) and it seems the  
freetype header files where just dropped from the maintainer in  
November 2008: http://sisyphus.ru/srpm/Sisyphus/libagg/patches/0

Don't know why?

Regards,
Werner

Hi Valery:

For the 2.5 agg development package on Debian testing, I get the following
result:

irwin@raven> dpkg --listfiles libagg-dev |grep agg_font_freetype.h
/usr/include/agg2/agg_font_freetype.h

I also notice there is a libaggfontfreetype.a library which I assume
from the name is associated with that header.

My guess is AltLinux has just not configured a complete version of libagg
for the binary version of that library that they provide. libagg does
produce some outstanding looking results for wxwidgets. So if you have an
interest in wxwidgets, then it might be worthwhile for you to configure and
build your own libagg version that does not have the AltLinux limitation.
But that is probably a lot of work so just using the -DHAVE_AGG=OFF option
and accepting poor-looking wxwidgets results as a result may be the better
choice if you don't have much interest in wxwidgets.

Alan
