If you only want to get a figure where the rendering of the text is done with
latex, you can use savefig in pgf format. As an example:
Contents of matplotlibrc:
[...]
backend : Qt4Agg
pgf.rcfonts : False
pgf.texsystem : pdflatex
pgf.preamble \usepackage{path_to_your_document/foo}
[...]
Script to create the figure:
#!/usr/bin/env python
import matplotlib.pyplot as plt
import numpy as np
x = np.linspace(0, 4. * np.pi)
y = np.sin(x) ** 2
fig = plt.figure(figsize=(3, 3))
ax = plt.gca()
ax.plot(x, y)
ax.set_xlabel(r'$x$')
ax.set_ylabel(r'$\sin \left( x \right) ^ 2$')
plt.savefig('path_to_your_document/foo.pgf')
Main document:
\documentclass{article}
\usepackage{foo}
\begin{document}
\begin{figure}[H]
\input{foo.pgf}
\end{figure}
\end{document}
Style file (foo.sty):
\usepackage{amsmath}
\usepackage{float}
\usepackage{fouriernc}
\usepackage{graphicx}
\usepackage{pgf}
The main problem with this, is that you can not resize the figure (i.e., with
a resizebox) without also resizing the text. If you want to get the figure
with a bigger or smaller size, you have to regenerate the file changing its
figsize. The benefit of this method is that all the drawing is made by latex,
so you have perfectly matched fonts, colors...
