Thanks for the quick and
helpful response John. I seem to more or less
up and running. Two things though. The first time I run the commands
in your e-mail I get an error, but the files seems to be created
correctly.

Looking at the code, it seems like SystemExit is raised any time the
png doesn’t already exist.
I am running these lines inside ipython, if that matters. Something
about my system doesn’t like the SystemExit being raised.
My second question is this. I am running Linux here at home and the
install of dvipng went really smooth. Is there a windows port of
dvipng? I may need to use windows at school.
Thanks,

TeX/LaTeX plus dvipng is really the right way to solve this problem. Coincidentally, I have been working to incorporate tex into backend_agg via dvipng (and into backend_ps via psfrag) and matplotlib has a tex manager class So if you don't mind installing tex and dvipng (on my Ubuntu system is is simply > sudo apt-get install dvipng then you can use the matplotlib texmanager class to handle the system calls, cacheing results it's seen before and so on >>> from matplotlib.texmanager import TexManager >>> m = TexManager() >>> pngfile = m.make_png("\TeX\ is Number $e^{-i\pi}$!", dpi=100) >>> print pngfile /home/jdhunter/.tex.cache/5b723d2ea8d0f15af94ec585aece1582_100.png You need to make sure you have texmanager revision 1.2 from CVS (or later). Of course if you are on a platform where TeX is not easily installed, this won't help much. In that case, you can use matplotlib to create the math images for you, but I would use the mathtext parser directly rather than the whole figure / axes api. Let me know if you still want/need to use mpl for this and I'll give you some pointers.
