Hello,
I recently upgraded matplotlib v0.98.5 to 1.0. Now when I try to plot data
using latex for the figure labels my scripts fail. I have not changed my code
so I'm not sure where the error is coming from. I have tried reinstalling and
updating MikTex and Ghostscript but that has not helped (I'm running Windows 7
and Python 2.6). The actual error I get is below. Any thoughts?
Thanks,
Steve
