It might be in a format that matplotlib doesn't really handle. However, Helvetica is one of the "core fonts" in PDF so if you set pdf.use14corefonts to True, you should be able to use Helvetica, and the reader application will supply the font (or approximate it with something else). This is deprecated in the latest version of the spec, but it should work just fine. > i verified that plt.rcParams gets modified to use 'Helvetica' as the value > for font.family, etc. but i still get the default font used in all of these > figures. > I just wanted to add: if i simply set the font to Arial, using > > rc('font',**{'family':'sans-serif','sans-serif':['Arial']}) > > then it works.

The font-selection system is somewhat complicated. I suggest running your script with --verbose-debug with both Arial and Helvetica as the value of font.sans-serif, and diffing the outputs to see what is going on. I suspect that Arial is a TTF file while Helvetica is in some Mac-specific format. The best solution would be to make matplotlib handle those formats, but probably the most practical solution is to use something like fondu to convert the font into TTF: http://fondu.sourceforge.net/ -- Jouni K.
