Hey everyone, this is more a how-to / feature request than a question... Normally, my workflow for embedding images in LaTeX is as follows:
1) produce ps-file 2) use pstoedit (xfig) to separate text/math (LaTeX-typesettable) from the image 3) save as pdf_t and pdf, respectively 4) \input this in the LaTeX document -- pdflatex will then set the text at every compilation. This has the advantage that I can change fonts etc without having to redo all the figures. I was trying to do so with matplotlib 0.98.3 and pstoedit 3.45 on a 64bit Ubuntu 8.10. I followed the instructions in the matplotlib cookbook but kept experiencing problems when calling pstoedit [1], the xlabels and ylabels were somehow converted to Courier but not put in the "text" part, "." would become ":" and so on. Solution brought this thread http://www.nabble.com/Switching-between-different-font-settings-ts21279388.html which suggested using OldScalarFormatter (thanks at this point also from my side, Jouni) -- which works, see attached example. So much for the "how-to-part" -- obviously, my suggestion is now to not force users to have math-labels. I have to admit that I am not aware of the drawbacks of OldScalarFormatter, but alone the name makes me think that it might be not the best solution... Thanks and best regards, Sebastian. P.S.: why actually does ax.yaxis.get_ticklabels()[1].get_text() return an empty string when called before savefig? P.P.S.: I expect to be offline several days, so please excuse me if I won't be answering timely.
