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.
