Re: [Matplotlib-users] Problem changing font properties

[James B. <bo...@ll...>]

Thanks for your help. Encouraged by your results I tried some more 
experiments.
There appears to be some hysteresis in matplotlib fonts ( at least my 
installation).
Unsaid(!!!)  in my message was that I initially ran the PS plot with 
the default fonts and generated a defective PS file, and then I tried 
to change the font properties. After running the rc(font, **fontDict) 
command I still generated a defective file but a different size - so 
something changed.
However, if I just run the rc(font, **fontDict) command sequence first 
without ever trying the defaults fonts all goes well and I get a fine 
PS file.
Evidently, some aspects of the old font are retained.

Thanks again,
--Jim
