Re: [Matplotlib-users] matplotlib-0.99 font incompatibility?

[per f. <per...@gm...>]

i figured out what i did wrong and so am writing it here in case it
helps others.

the basic issue is that the .ttf font was missing in the new
matplotlib directory. to discover this, i ran python with
--verbose-debug as suggested in previous threads by others.  then i
copied my version of Helvetica.ttf into:

/Library/Python/2.5/site-packages/matplotlib/mpl-data/fonts/pdfcorefonts

and

/Library/Python/2.5/site-packages/matplotlib/mpl-data/fonts/ttf

then everything worked and i was able to change fonts to helvetica.

thanks.
