Re: [Matplotlib-users] Problems with sans-serif fonts and tick labels with TeX

[Felix P. <fe...@ne...>]

Some output using the different settings in the functions I just sent. As you can see the only problem are greek letters and some math symbols. It may be possible to improve this situation using xetex (http://matplotlib.org/users/pgf.html), but I did not try this out yet.

> H, I'm using sfmath, too. I actually wrote a helper function to switch fonts. The preambles are the result of long-term trial and error. Normally, my preambles include some more custom commands which I left out here because they would be distracting. I always wondered why matplotlib doesn't do this kind of font switching out of the box.
