[Matplotlib-users] mathtext and raw strings

[N. V. <mit...@we...>]

Hello everyone,

I intended to use the capabilities of mathtext as presented on the 
matplotlib example page and the tutorial page. The examples given are 
quite clear; yet they always assume that you pass the string that should 
be interpreted as raw string, e.g.

r'$\sum_{i=0}^\infty x_i$'

However, in my application the user types the labels/title/whatever text 
in a gtk entry field and this string, which is a unicode string, is then 
passed on to the matplotlib OO interface.  And as it is right now, I 
just get the text as it is, so no fancy sum or infinity sign.

I'd appreciate your help,

Niklas.
