[Matplotlib-users] Seperate text from PGF Graphics?

Hi,

I'm currently working on my master thesis, which heavily involves 
creating plots and images. I recently found out about the pdf_tex 
feature of Inkscape, which basically creates a seperate LaTeX file 
besides the normal *.pdf output, to store the text. The advantage of 
this method is that the text displayed in the included pdf matches 
exactly the size of your font in the rest of your document, even when 
resizing the image. This is just a brilliant feature as it allows me to 
fit the width of the images to my column or textwidth while having the 
same font size for all images, it just looks amazing. While this work 
pretty well for the images i draw myself, i tried to find a similar 
feature for my matplotlib plots. The closest format to pdf_tex i found 
was pgf. But i have a major issue with this pgf format. When i resize 
the picture in LaTeX it also resizes the font size. Is there a way to 
get arround this issue? Guess i could resize the plot in matplotlib to 
fit approximately the page width and just include the pgf without 
resizing it, but i want a consistent look of all my images/plots in my 
thesis. Right now, I don't see any advantage over using just a plain pdf 
output using matplotlib, besides using the same font as in the rest of 
my document (but using pgf to include my plots / images also takes a lot 
more time to compile).

I'm not bound to pgf images, so if there is a vector graphic solution 
which let's me keep the same font size no matter how i resize my 
picture, I would go with it. I guess i could save the image as a svg and 
save it with inkscape to pdf_tex, but as i allready mentioned i have a 
lot of images / plots.

I would really appreciate any suggestions.

Regards

PS: Excuse my bad english :)
PPS: It doesn't seem to be easy to resize a pgf picture to the textwidth 
or columnwidth either (because of the \input statement, right now i'm 
using \scalebox{}{}). So an alternative to pgf wouldn't be bad.
