The best thing I've come up with so far is this, which will write out each page
to a pdf file, then use subprocess to call 'pdfunite' to join the pdfs.
I like the xits-math + xits - it gives a much more unified look so the text and
math fonts match.
Only problems:
It's extremely slow
The resulting pdf has duplicate embedded fonts
------------------------------------
import matplotlib as mpl
mpl.use ('pgf')
import numpy as np
import matplotlib.pyplot as plt
pgf_with_custom_preamble = {
"font.family": "serif", # use serif/main font for text elements
"text.usetex": True, # use inline math for ticks
"pgf.rcfonts": False, # don't setup fonts from rc parameters
'pgf.texsystem' : 'lualatex',
"pgf.preamble": [
r'\usepackage{fontspec,xunicode}',
r"\usepackage{unicode-math}", # unicode math setup
r"\setmathfont{xits-math.otf}",
r'\usepackage{cancel}',
r'\usepackage{xcolor}',
r'\renewcommand{\CancelColor}{\color{red}}',
r'\setmainfont{xits}', ]
}
mpl.rcParams.update(pgf_with_custom_preamble)
for ...
plt.savefig ('xxx.pdf')
subprocess.call (['pdfunite'] + files + ['test_uw4.pdf'])
