I have trouble getting any symbols or any super/sub scripts to work since I upgraded to 1.0 a few months ago. I always get a message saying that some font isn't found. This occurs whenever I try to put symbols, superscripts, or subscripts in a label, or when I use a log scale (because then it MPL has to use superscripts). I have tried changing my matplotlibrc file but haven't found any combination of settings that help.
To illustrate the problem, I have included three files, one python file and the other the error as captured from the output as well as my matplotlibrc file. The python file is trivial: # ------------------------------------------------- import matplotlib.pyplot as pyplot pyplot.plot([1,2,3], label='$\alpha > \beta$') pyplot.legend() pyplot.show() # ------------------------------------------------- Can someone please help me figure out what is wrong? I'm on a Mac running 10.6, python 2.6, matplotlib 1.0, and I have TeX installed. Thanks, Jeremy
