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

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

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!

Re: [Matplotlib-users] Widgets: How to disconnect spanselector once selection is completed
I have been working on this problem for the last week and I have finally started to understand how it should work: 1) Events and plt.show must be running all the time. Indeed, the latter is designed to be set implemented at the end of the code. The events call should be just before 2) To change the data on your figures you can use a key event. This post illustrates the right way to do it and it includes a class for it http://stackoverflow.com/questions/14347630/using-events-with-matplotlib-in-a-for-loop?rq=1 3) The problem with this structure is that your code must be fragmented in different methods. You need to make sure to define your variables in the main code so they can be imported across different methods (I am still struggling with this... I will post an example code when I am done) One additional question: When I try to run the cursor widget with the spanselector widget the widgets glitches in a rather... painful way to the eye way... Is there anyway to avoid this? I have been playing with the cursor useblit widget but no luck -- View this message in context: http://matplotlib.1069221.n5.nabble.com/Widgets-How-to-disconnect-spanselector-once-selection-is-completed-tp40949p40989.html Sent from the matplotlib - users mailing list archive at Nabble.com. -- Get 100% visibility into Java/.NET code with AppDynamics Lite It's a free troubleshooting tool designed for production Get down to code-level detail for bottlenecks, with 2% overhead.
