Sorry, I meant to reply to the list.
After clearing the fontlist cache, I was able to get this fix working.
Just to summarize:
-
download unicode version of computer modern fonts (http://sourceforge.net/projects/cm-unicode/files/)—make sure to get the ttf version
-
clear out the fontlist cache (rm ~/.matplotlib/fontList.cache)
-
add the following to ~/matplotlib/matplotlibrc:
font.family: serif
font.serif: CMU Serif
- alternatively, you could leave the default as sans serif and use the computer modern sans serif (unicode version):
font.sans-serif: CMU Sans Serif
These changes produce plots where the size of normal text matches that of mathtext.
Thanks for you help, Mike!

Hey Mike,
Thanks for your reply. That makes sense.
An alternative work around (I presume) would be to install the computer modern unicode fonts (I made sure to install the ttf version). However, I’m having trouble getting MPL to find the fonts.
The installed font is listed when calling mpl.font_manager.OSXInstalledFonts(), but it’s not found when calling mpl.font_manager.findfont (with various names that would make sense: cmunrm, CMU Serif, etc.)
Any ideas on what I’m doing wrong?

Umm, … last email on this topic, I promise.
Is there any reason the font family rc parameter is case sensitive, while the findfont input is case insensitive? In other words, replacing
font.serif: CMU Serif
with
font.serif: cmu serif
does not work. On the other hand, both of the following work:
mpl.font_manager.findfont(‘cmu serif’)
mpl.font_manager.findfont(‘CMU Serif’)
This caused me problems when debugging my earlier font troubles.
Best,
-Tony

I'll look into the case-sensitivity issue -- I'm not sure why that is the case.

On further looking into these fonts, it seems they're not appropriate at the moment. They are missing a number of math-related symbols (such as infinity, for example). They are worth keeping an eye on, because they have a much better and more open framework for being built vs. the Bakoma fonts which are essentially "closed-source" though free for redistribution. (i.e. it makes it a lot harder to fix problems in them). Given the time, I may look into what it would take to start adding these new symbols.
I'll look into the case-sensitivity issue -- I'm not sure why that is the case.
This has now been fixed in SVN.
