I installed acroread and I was also able to view everything fine with it
whereas xpdf and evince showed the bug.

Hmmm. This would imply that your versions somehow do something that makes xpdf
happy.

Looks like it doesn't know what \begin{python} means. Did you put python.sty
in the same directory as text.tex?

I see the problem with xpdf when I simply include the plots which means that
python.sty was just a red herring. python.sty isn't the problem.

xpdf still croaks for me. Perhaps using the bleeding edge of matplotlib would
fix? I'm using Ubuntu 8.04 which has python-matplotlib version
0.91.2-0ubuntu1.

Here is what I got:
Beamer 3.07-1
python 2.5.2
matplotlib 0.91.2-0ubuntu1
Acroread 8.1.2_SU1
xpdf 3.02-1.3ubuntu1
Ironically, all my stuff is newer than yours except for matplotlib. Sounds
like bleeding edge of matplotlib must be tried next.

Glad I could help!

Re: [Matplotlib-users] zorder seems to cause problems when embed python in latex files
With the file you sent, I can see the messed up footer in xpdf, but not
in acroread. There are a number of times that I have seen xpdf not
completely support the PDF spec, and this may be one of them.
Creating my own files, however, I'm not able to reproduce this here.
When I compile your test.tex, I get an error, even though it seems to
have loaded the python.sty file. Not sure why (see attached log).
When I generate the plots "offline", and then hack test.tex to simply
include the files, everything works fine, and I don't see a problem with
the footers with either xpdf or acroread.
There was a recent bug discovered in matplotlib where PDF files weren't
always getting flushed completely. I don't *think* that's the cause of
this, but if you could reproduce what I did (generate the plots
independently of TeX and then load them), and that works for you, that
might point to something like that.
There was also a bug a few months back where xpdf didn't like the way
matplotlib handled reusing the same graphic multiple times (which is
used for markers). That may be why you're seeing the footer bug and I'm
not -- you didn't mention which version of matplotlib you're running, so
it's hard to say.

That python.sty stuff looks really cool, by the way. I haven't come

Wow thanks. I was afraid no one would respond. I suppose if Matplotlib is so
mature that we are left worrying about bugs when embedding it in Latex then it
has come a long way. :)
I created a tiny test.tex that shows the problem. Just type
pdflatex -shell-escape test.tex ; xpdf test.pdf
in the same directory with the 2 files test.tex and python.sty below and
attached. I also attached the final PDF since you asked for it.

In general, matplotlib doesn't explicitly try to be careful about state in its output since it is really the embedding applications job (in this case Beamer/LaTeX) that is supposed to ensure that anything it embeds does not have external side effects.

[Matplotlib-users] zorder seems to cause problems when embed python in latex files
LaTeX can accept embedded Python code with a python.sty file. This is handy to dynamically generate plots with Matplotlib for a LaTeX slide presentation. I successfully embedded lots of matplotlib plot code into my slides and then had problems with zorder. For some reason zorder seems to mess up the footer of my Beamer/LaTeX slides. (For some reason zorder setting make the footer shrink in size.) Is there any weirdness or side effects about zorder I should be aware of that would explain this?
