问题
I'm having a problem with using latex fonts in matplotlib, in so far that they do not show up in interactive windows. Any help would be much appreciated :)
I believe the issue did not exist on my system before, maybe a software update messed something up last month..
The default Latex font works without problems.
Utopia / Fourier is broken, for example the following example (I replaced my home directory by a tilde in the output, everything else is just as I got it):
import matplotlib.pyplot as plt
plt.rcParams.update({
'text.usetex': True,
'text.latex.preamble': [
r"\usepackage{fourier}",
]
})
plt.plot([1,2],[3,4])
plt.xlabel('$x$')
plt.savefig('test.pdf')
gives the expected output in pdf, but the interactive window has no text:
I get a lot or warnings (I assume one for every text item, or for every glyph?):

the files which dvipng cannot find are available on my system:
$ locate ps2pk.map

~/.texmf-var/fonts/map/dvips/updmap/ps2pk.map
/usr/local/texlive/2013/texmf-dist/fonts/map/dvips/updmap/ps2pk.map

$ locate psfonts.map

/usr/local/texlive/2013/texmf-var/fonts/map/dvips/updmap/psfonts.map
Another try, with Concrete and Euler gives errors instead of warnings:
import matplotlib.pyplot as plt
plt.rcParams.update({
'text.usetex': True,
'text.latex.preamble': [
r"\usepackage{ccfonts,eulervm}",
r"\usepackage[T1]{fontenc}",
]
})
plt.plot([1,2],[3,4])
plt.xlabel('$x$')
plt.savefig('test.pdf')
this gives the following output:
