I am having trouble executing the example for typesetting labels with latex from http://matplotlib.org/users/usetex.html. Copying the standard example, tex_demo.py, to a file and executing it gives the following output: Traceback (most recent call last): File "scratch.py", line 21, in <module> plt.savefig('tex_demo') File "/usr/lib/pymodules/python2.7/matplotlib/pyplot.py", line 561, in savefig return fig.savefig(*args, **kwargs) File "/usr/lib/pymodules/python2.7/matplotlib/figure.py", line 1421, in savefig self.canvas.print_figure(*args, **kwargs) File "/usr/lib/pymodules/python2.7/matplotlib/backend_bases.py", line 2220, in print_figure **kwargs) File "/usr/lib/pymodules/python2.7/matplotlib/backends/backend_agg.py", line 505, in print_png FigureCanvasAgg.draw(self) File "/usr/lib/pymodules/python2.7/matplotlib/backends/backend_agg.py", line 451, in draw self.figure.draw(self.renderer) File "/usr/lib/pymodules/python2.7/matplotlib/artist.py", line 55, in draw_wrapper draw(artist, renderer, *args, **kwargs) File "/usr/lib/pymodules/python2.7/matplotlib/figure.py", line 1034, in draw func(*args) File "/usr/lib/pymodules/python2.7/matplotlib/artist.py", line 55, in draw_wrapper draw(artist, renderer, *args, **kwargs) File "/usr/lib/pymodules/python2.7/matplotlib/axes.py", line 2086, in draw a.draw(renderer) File "/usr/lib/pymodules/python2.7/matplotlib/artist.py", line 55, in draw_wrapper draw(artist, renderer, *args, **kwargs) File "/usr/lib/pymodules/python2.7/matplotlib/axis.py", line 1105, in draw self.label.draw(renderer) File "/usr/lib/pymodules/python2.7/matplotlib/artist.py", line 55, in draw_wrapper draw(artist, renderer, *args, **kwargs) File "/usr/lib/pymodules/python2.7/matplotlib/text.py", line 594, in draw self._fontproperties, angle, mtext=self) File "/usr/lib/pymodules/python2.7/matplotlib/backends/backend_agg.py", line 241, in draw_tex self._renderer.draw_text_image(Z, x, y, angle, gc) OverflowError: cannot convert float infinity to integer My system is Linux mwlaptop 3.16.0-24-generic #32-Ubuntu SMP Tue Oct 28 13:07:32 UTC 2014 x86_64 x86_64 x86_64 GNU/Linux My matplotlib version is 1.3.1, and I am using standard packages from my Ubuntu 14.10 distribution.

I just downgraded to matplotlib 1.1.1 and now everything works. Looks like a regression to me.

To: Martin Wiebusch <mwi...@gm...> My first guess is that there is that some thing wrong with your latex installation as the images on the website are regenerated as part of building the documentation. I can not reproduce this problem on a 1.4.2 installation on my computer. Try cleaning out the tex.cache folder in either or both of matplotlib.get_cachedir() or matplotlib.get_configdir().

It might be a good idea to mention matplotlib.get_cachedir() and matplotlib.get_configdir() explicitly under 'Troubleshooting' on the web page. Currently there is a link which points you to matplotlib.get_configdir() (which was empty in my case) but not matplotlib.get_cachedir(). Best regards, Martin. -- Thomas Caswell tca...@gm...
