Re: [Matplotlib-users] possible bug in font manager: RuntimeError: Not an AFM file

Hi

Thanks for the replies. I replaced all the fonts of my script to
Helvetica and it works fine. Yes, I'm using ps.fonttype=3.  The files
are pretty small.
But I still couldn't find out why matplotlib was getting that ttf Vera...

Cheers,
Marco
