Re: [Matplotlib-users] Polar graph radial labels

[Paul H. <pmh...@gm...>]

Luke,

I don't have an answer to your question, but I can confirm what your
seeing with the attached image. I generated this figure with MPL
1.1.0, Python 2.7.1, on Windows 7 with ipythonqt and the inline
backend. I filed an issue here:
https://github.com/matplotlib/matplotlib/issues/680. If I find time
tonight, I'll take a stab at tracking this down.

Thanks,

-paul
