[Matplotlib-users] Mathtext doesn't work on the PS backend

[Serge B. <se...@op...>]

I'm a new user of matlibplot, and have difficulties in making mathtext to work with the PS backend. Instead of the math symbols, the raw TeX expression is displayed. Mathtext works fine on the GUI backends and on raster images output, though.

The following quote from matplotlib web page made suggests that mathtext should work for PS output:
"mathtext now embeds the TrueType computer modern fonts into the PS file, so what you see on the screen should be what you get on paper"
Did I misunderstood?

I am on debian unstable and initially tried Vittorio's packages. Thinking that this could be the problem, I resolved to install matplotlib from sources, but the result is the same.
I did check that BUILD_FT2FONT=1 is set.

Thank you in advance for any help,

Serge
