            <br>
            I am preparing figures with the following matplotlib
            preamble:<br>
            <br>
            plt.rc('font', **{'family':'serif', 'serif':['Computer
            Modern Roman'],<br>
            &nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp; 'monospace':['Computer Modern
            Typewriter']})<br>
            params = {'backend': 'ps',<br>
            &nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp; 'text.latex.preamble': [r"\usepackage{upgreek}",<br>
            &nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;
            r"\usepackage[nice]{units}"],<br>
            &nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp; 'axes.labelsize': 12,<br>
            &nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp; 'text.fontsize': 12,<br>
            &nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp; 'legend.fontsize': 8,<br>
            &nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp; 'xtick.labelsize': 10,<br>
            &nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp; 'ytick.labelsize': 10,<br>
            &nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp; 'text.usetex': True,<br>
            &nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp; 'figure.figsize': fig_size,<br>
            &nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp; 'axes.unicode_minus': True}<br>
            plt.rcParams.update(params)<br>
            <br>
            <br>
            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).<br>
            <br>
            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".<br>
            <br>
            <br>
            Is there an option to specify a .cls file in rcParams that
            should be used for rendering? <br>
            I tried: <br>
            text.latex.preamble': [r"\documentclass[twoside]{mycls}",<br>
            &nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp; r"\usepackage{upgreek}",<br>
            &nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;
            r"\usepackage[nice]{units}"],<br>
            but then I get the error:<br>
            ! LaTeX Error: Two \documentclass or \documentstyle
            commands.<br>
            <br>
            How to overwrite default matplotlib one? my matplotlibrc has
            a commented preamble.<br>
            <br>
            <br>
            <br>

          This might have been fixed at one point.&nbsp; Which version of
          matplotlib are you using?<br>

    I found the solution. My LaTeX file uses the package amsmath, which
    also loads amstext. And that is invoked when using \text{} or
    \textnormal{} inside a formula.<br>
    <br>
    So the solution in matplotlib is to add the following to the
    preamble:<br>
    'text.latex.preamble': [r"\usepackage{upgreek}",<br>
    &nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp; r"\usepackage[nice]{units}",<br>
    &nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp; <span class="comment-copy"><code>r"\usepackage{amstext}"</code></span>],<br>
    <br>
    I was using matplotlib 1.1, now updated to 1.1.1, but that did not
    affect it. Also, I am not using the built-in LaTeX typesetting.<br>
