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.
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,
