You can minimize the amount of package and module-level state

I vaguely recall a bug whereby mathtext on PDF was upside down (because
the direction of the y-axis was not being inverted)... but I can't find

It does seem to work in 0.90.1 and 0.91.2 (on Linux at least). Are you
able to upgrade?

I'd guess PNG won't get much smaller because you have a lot of different
colored pixels. PNG compresses most when you have a sparser plot. I'd
suggest that you try using JPG. It will compress the multi-colored portion
of your plot way down. You may see a few artifacts if you look carefully at

1. Moving to matplotlib-0.91.2 solved the problem with PDF generation

2. Installing matplotlib-0.91.2 on Linux required installing these
