Hey folks,
I’m having trouble getting a consistent sans-serif font in my figures:
https://gist.github.com/phobson/5503195 (see attached output)
This is pretty much the same issue as this Stack Overflow post:
http://stackoverflow.com/questions/12322738/how-do-i-change-the-axis-tick-font-in-a-matplotlib-plot-when-rendering-using-lat
But, the end result I’m looking for is to process the whole figure through latex and have sans-serif fonts everywhere, even in math text.
The accepted solution on SO is to manually set the font properties of the ticks for the figure prior to saving.
Is there a configuration-based work around for this? I’d like to avoid having to pick through everywhere that I call fig.savefig and manually set tick font properties if possible.
Thanks,
-Paul
Sorry for the confusion. The prior attachment was generated with the solution on SO. (Though you can still see the serif math fonts.)
Here’s the correct output from the Gist I included (purely-configuration based).

I think the confusion here stems from the fact that you're mixing TeX and non-TeX font commands.
This turns on TeX mode, so all of the text is rendered with an external TeX installation:
rc('text', usetex=True)
In this line, setting it to sans-serif will get passed along to TeX, but a specific ttf font name can not be used by TeX, so the second part (involving Helvetica) is ignored. And setting the default body text in TeX does not (by default) change the math font. This is (unfortunately standard TeX behavior).
rc('font',**{'family':'sans-serif','sans-serif':['Helvetica']})
This affects the font set used by matplotlib's internal mathtext renderer, and has no effect on TeX:
rc('mathtext', fontset='stixsans')
The solution I use when I want all sans-serif out of TeX is to use the cmbright package, which can be turned on by adding:
rc('text.latex', preamble=r'\usepackage{cmbright}')
That may require installing the cmbright LaTeX package if you don't already have it.
I know all this stuff is confusing, but providing a flat interface over both the internal text rendering and the TeX rendering isn't really possible -- they have different views of the world -- and I'm actually not sure it's desirable. Though I wonder if we couldn't make it more obvious (somehow) when the user is mixing configuration that applies to the different contexts.

Mike,
Thanks for the guidance. I know this stuff is complicated and the work
everyone has put into it to make it work is fantastic.
I now see that this was more of TeX issue than an MPL configuration issue.
Your help prompted me to find this solution (similar to yours):
mpl.rcParams['text.latex.preamble'] = [
r'\usepackage{siunitx}', # i need upright \micro symbols, but you
need...
r'\sisetup{detect-all}', # ...this to force siunitx to actually
use your fonts
r'\usepackage{helvet}', # set the normal font here
r'\usepackage{sansmath}', # load up the sansmath so that math ->
helvet
r'\sansmath'] # <- tricky! -- gotta actually tell tex to use!
Thanks again!

Wow. That’s some serious TeX voodoo magic! Want to work that into
an example that we could include in the docs?

I am using the sfmath package for this purpose.
There is a nice comparision of the different approaches to get sans-serif math fonts at the bottom of the sfmath page: LaTeX sans serif math fonts with sfmath.sty
Gladly. I'll try to find time to cook up PR building off of the existing
example over the weekend.

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.

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.
