Hi,

Thanks for your answer, I have been able to change the font but the 
things I don't like, no that I think it's not coherent with other 
matplotlib command is that in the font you can't ask fontname=Courier" 
and fontstyle="Italic" (the term angle was bad in my precedent mail :) 
). That doesn't work.
Perhaps it's a problem with my installation (debian and package from 
this distribution and Suse and matplotlib install by hand) but I have an 
error message when I'm trying to have some Italic. I wa trying to use 
the script:

http://matplotlib.sourceforge.net/examples/fonts_demo.py

and I have this message when the script want plot the italic fonts:

Could not match cursive, normal, normal.  Returning 
/usr/share/fonts/truetype/ttf-bitstream-vera/Vera.ttf
Could not match fantasy, normal, normal.  Returning 
/usr/share/fonts/truetype/ttf-bitstream-vera/Vera.ttf
Could not match sans-serif, italic, normal.  Returning 
/usr/share/fonts/truetype/ttf-bitstream-vera/Vera.ttf
Could not match sans-serif, italic, normal.  Returning 
/usr/share/fonts/truetype/ttf-bitstream-vera/Vera.ttf
Could not match sans-serif, italic, normal.  Returning 
/usr/share/fonts/truetype/ttf-bitstream-vera/Vera.ttf

I defined the TTFPATH and I have no change.

I have something else weird with the fonts. I verified i=with Ipython and

from matplotlib.font_manager import fontManager, FontProperties
from matplotlib.matlab import *
p = FontProperties()
p.get_family()

the different fonts available. I obtain:

['Lucida Grande',
 'Verdana',
 'Geneva',
 'Lucida',
 'Bitstream Vera Sans',
 'Arial',
 'Helvetica',
 'sans-serif']

but if I'm trying to use the font Arial and italic in the script that 
give me this message:
 
Could not match sans-serif, italic, normal.  Returning 
/usr/share/fonts/truetype/ttf-bitstream-vera/Vera.ttf

It's seems that the change introduce in the script is not use and that 
matplotlib are using only Vera fonts with no style.




fonts = {
      'color'               : 'k',
      'fontname'            : 'Courier',
      'fontweight'          : 'bold',
      'fontstyle'           : 'italic',
      'fontsize'            : 'xx-large'
      }


ylabel('toto',fonts)

give me exactly the same things than:

fonts = {
      'color'               : 'k',
      'fontname'            : 'Arial,
      'fontweight'          : 'bold',
      'fontstyle'           : 'italic',
      'fontsize'            : 'xx-large'
      }


ylabel('toto',fonts)


The only things that seems to work is the fontweigth.

I have exactly the same things if I'm doing:

t = ylabel('label')
set(t,'fontstyle','italic')


I did probably something wrong but I can't find where so I'm asking for 
some help,

          Nicolas
