Re: [Matplotlib-users] font.latex.package in matplotlibrc has no effect using MiKTeX

[Samuel M. S. <sm...@sa...>]

If you use the exact same text then it will not change the font  
because matplotlib caches the tex redering of text by the name of the  
text. You have to delete
the matplotlib tex cache in ~/.matplotlibrc/tex.cache. That will  
force it to regenerate the text using the new font.

For example if your plot has a label "Meters" then matplotlib will  
use the cached rendering of "Meters". It isn't smart enough to notice  
that the cached version uses a different font and therefore must be  
re-rendered.
