[Matplotlib-users] subscript size different than in LaTeX document

[Mogliii <mo...@gm...>]

Hi,

I am preparing figures with the following matplotlib preamble:

plt.rc('font', **{'family':'serif', 'serif':['Computer Modern Roman'],
                  'monospace':['Computer Modern Typewriter']})
params = {'backend': 'ps',
          'text.latex.preamble': [r"\usepackage{upgreek}",
                                  r"\usepackage[nice]{units}"],
          'axes.labelsize': 12,
          'text.fontsize': 12,
          'legend.fontsize': 8,
          'xtick.labelsize': 10,
          'ytick.labelsize': 10,
          'text.usetex': True,
          'figure.figsize': fig_size,
          'axes.unicode_minus': True}
plt.rcParams.update(params)


But when using subscript and superscript in math mode the sizes end up
different than in my LaTeX document (my .cls is using "book" as base class).

Attached are two screenshots of it rendered from matplotlib and from
Latex (sorry for the different sizes). The "mean" is clearly of
different size in relation to the "d".


Is there an option to specify a .cls file in rcParams that should be
used for rendering?
I tried:
text.latex.preamble': [r"\documentclass[twoside]{mycls}",
                                  r"\usepackage{upgreek}",
                                  r"\usepackage[nice]{units}"],
but then I get the error:
! LaTeX Error: Two \documentclass or \documentstyle commands.

How to overwrite default matplotlib one? my matplotlibrc has a commented
preamble.
