The font lookup mechanism has been much improved in 0.91.2 -- you may
want to try using that. In 0.90.x, often if you don't get a perfectly
exact match for a font, it reverts back to the default "Vera Sans".
Vera Sans, however, is not a fixed-width font. Can you provide the png
file of fonts_demo.py so I can be sure of what is happening? One way to
diagnose this is to dorc("verbose", level="debug-annoying")
which will print out a bunch of stuff related to font lookup. Attach
the output here and I'll have a look at it to try to figure out what may
be going wrong.Cheers,

Hi Michael,
I put in the rc line you suggested below into fonts_demo.py but didn't see it
print any extra info (but did confirm in ipython that rcParams showed
verbose.level had changed to "annoying"). It just quietly finished otherwise.
Did I miss something here?
I've linked the output of fonts_demo.py to;

If I need to upgrade matplotlib above 0.90.1 I guess I'll have to build it
separately unfortunately. We're trying to stick to the standard ubuntu
packages that get pulled in for that release.
Thanks for your help,
Paul
