I tested it under Linux now, and I see your problem. The latex files don't compile cleanly, this is why you get the
error. You can find the .tex files under ~./matplotlib/tex.cache
It looks like you have a problem with the font encoding when using unicode characters.
This works for me under Linux and Windows:
import numpy as np
import matplotlib as mpl
mpl.rcParams['text.latex.preamble'] = [r'\usepackage{amsmath}' , r'\usepackage[T1]{fontenc}']
mpl.rcParams['text.latex.unicode'] = True
mpl.rcParams['text.usetex'] = True
import pylab as py
py.axhspan(8400,8730,alpha=0.15)
py.title(u'Wyniki eksperymentu pomiaru gęstości ciała stałego',size='large',family='serif')
py.ylabel(r'$\text{lol}$',size='large',family='serif')
py.grid(True)
py.show()

Doesn't look like you're using math.usetex & therefore are not actually
using latex, but mpl's stripped down tex implementation.
Try setting usetex to True, or alternatively I think you could use \mathrm
instead of \text to get non mathematical text.

Hello,
I've been having some troubles with LaTeX in matplotlib. My example script:
#!/usr/bin/env python2
#-*- coding: utf-8 -*-
__author__ = 'Pawel Chojnacki'
__copyright__ ='Copyleft 2013 Pawel Chojnacki'
__version__ = '1.0'
__date__ = '29-03-2013'
__license__ = 'GPLv3'
import numpy as np
import matplotlib as mpl # Zmiana ustawien LaTeXa
mpl.rcParams['text.latex.preamble'].append(r'\usepackage{amsmath}')
#~ mpl.rcParams['text.latex.preamble'] = r'\usepackage{amsmath}'
#~ mpl.rcParams['text.latex.preamble']=[r"\usepackage{amsmath}"]
#~ mpl.rcParams['math.usetex'] = True
print mpl.rcParams['text.latex.preamble']
import pylab as py
py.axhspan(8400,8730,alpha=0.15)
py.title(u'Wyniki eksperymentu pomiaru gęstości ciała
stałego\n',size='large',family='serif')
py.ylabel((u'Gęstość ciała stałego ' +
r'$\frac{kg}{m^3}$'),size='large',family='serif')
#~ py.ylabel((r'$\text{lol}$'),size='large',family='serif')
py.ylabel((r'$\text{lol}$'),size='large',family='serif')
py.xlabel(u'Metoda pomiaru',size='large',family='serif')
py.grid(True)
py.show()
Gives me the following output:
['', '\\usepackage{amsmath}']
Exception in Tkinter callback

$\text{lol}$ (at char 0), (line:1, col:1)
And a blank window. The same line - $\text{lol}$ works pretty well in pure
LaTeX. While the package seems loaded, matplotlib doesn't send the command
as it's supposed to. Why is that?
Thanks in advance,
Pawel
