<p>You can use a subset of TeX markup in any Matplotlib text string by placing it
inside a pair of dollar signs ($).</p>
<p>Note that you do not need to have TeX installed, since Matplotlib ships
its own TeX expression parser, layout engine, and fonts. The layout engine
is a fairly direct adaptation of the layout algorithms in Donald Knuth's
TeX, so the quality is quite good (Matplotlib also provides a <code class="docutils literal notranslate"><span class="pre">usetex</span></code>
option for those who do want to call out to TeX to generate their text; see
<a class="reference internal" href="usetex.html"><span class="doc">Text rendering with LaTeX</span></a>).</p>
<p>Any text element can use math text. You should use raw strings (precede the
quotes with an <code class="docutils literal notranslate"><span class="pre">'r'</span></code>), and surround the math text with dollar signs ($), as
in TeX. Regular text and mathtext can be interleaved within the same string.
Mathtext can use DejaVu Sans (default), DejaVu Serif, the Computer Modern fonts
(from (La)TeX), <a class="reference external" href="http://www.stixfonts.org/">STIX</a> fonts (which are designed
to blend well with Times), or a Unicode font that you provide. The mathtext
font can be selected via <code class="docutils literal notranslate"><a class="reference internal" href="../introductory/customizing.html?highlight=mathtext.fontset#matplotlibrc-sample"><span class="std std-ref"><span class="pre">rcParams["mathtext.fontset"]</span></span></a></code> (default: <code class="docutils literal notranslate"><span class="pre">'dejavusans'</span></code>) (see
<a class="reference internal" href="../introductory/customizing.html"><span class="doc">Customizing Matplotlib with style sheets and rcParams</span></a>)</p>
<p>Here is a simple example:</p>
<div class="highlight-default notranslate"><div class="highlight"><pre><span></span><span class="c1"># plain text</span>
<span class="n">plt</span><span class="o">.</span><span class="n">title</span><span class="p">(</span><span class="s1">'alpha > beta'</span><span class="p">)</span>
</pre></div>
</div>
<p>produces "alpha > beta".</p>
<p>Whereas this:</p>
<div class="highlight-default notranslate"><div class="highlight"><pre><span></span><span class="c1"># math text</span>
<span class="n">plt</span><span class="o">.</span><span class="n">title</span><span class="p">(</span><span class="sa">r</span><span class="s1">'$\alpha > \beta$'</span><span class="p">)</span>
</pre></div>
</div>
<p>produces "<img src="../../_images/mathmpl/math-ca525d8410.png" srcset="../../_images/mathmpl/math-ca525d8410.png, ../../_images/mathmpl/math-ca525d8410-2x.png 2x" style="position: relative; bottom: -4px"/>".</p>
<div class="admonition note">
<p class="admonition-title">Note</p>
<p>Mathtext should be placed between a pair of dollar signs ($). To make it
easy to display monetary values, e.g., "$100.00", if a single dollar sign
is present in the entire string, it will be displayed verbatim as a dollar
sign. This is a small change from regular TeX, where the dollar sign in
non-math text would have to be escaped ('\$').</p>
</div>
<div class="admonition note">
<p class="admonition-title">Note</p>
<p>While the syntax inside the pair of dollar signs ($) aims to be TeX-like,
the text outside does not. In particular, characters such as:</p>
<div class="highlight-default notranslate"><div class="highlight"><pre><span></span><span class="c1"># $ % & ~ _ ^ \ { } \( \) \[ \]</span>
</pre></div>
</div>
<p>have special meaning outside of math mode in TeX. Therefore, these
characters will behave differently depending on <code class="docutils literal notranslate"><a class="reference internal" href="../introductory/customizing.html?highlight=text.usetex#matplotlibrc-sample"><span class="std std-ref"><span class="pre">rcParams["text.usetex"]</span></span></a></code> (default: <code class="docutils literal notranslate"><span class="pre">False</span></code>). See the
<a class="reference internal" href="usetex.html"><span class="doc">usetex tutorial</span></a> for more information.</p>
</div>
<section id="subscripts-and-superscripts">
<h2>Subscripts and superscripts<a class="headerlink" href="#subscripts-and-superscripts" title="Permalink to this heading">#</a></h2>
<p>To make subscripts and superscripts, use the <code class="docutils literal notranslate"><span class="pre">'_'</span></code> and <code class="docutils literal notranslate"><span class="pre">'^'</span></code> symbols:</p>
<div class="highlight-default notranslate"><div class="highlight"><pre><span></span><span class="sa">r</span><span class="s1">'$\alpha_i > \beta_i$'</span>
</pre></div>
</div>
<div class="math notranslate nohighlight">
\[\alpha_i > \beta_i\]</div>
<p>To display multi-letter subscripts or superscripts correctly,
you should put them in curly braces <code class="docutils literal notranslate"><span class="pre">{...}</span></code>:</p>
<div class="highlight-default notranslate"><div class="highlight"><pre><span></span><span class="sa">r</span><span class="s1">'$\alpha^</span><span class="si">{ic}</span><span class="s1"> > \beta_</span><span class="si">{ic}</span><span class="s1">$'</span>
</pre></div>
</div>
<div class="math notranslate nohighlight">
\[\alpha^{ic} > \beta_{ic}\]</div>
<p>Some symbols automatically put their sub/superscripts under and over the
operator. For example, to write the sum of <img src="../../_images/mathmpl/math-3a2e7f36d3.png" srcset="../../_images/mathmpl/math-3a2e7f36d3.png, ../../_images/mathmpl/math-3a2e7f36d3-2x.png 2x" style="position: relative; bottom: -3px"/> from <img src="../../_images/mathmpl/math-b69eb39e09.png" srcset="../../_images/mathmpl/math-b69eb39e09.png, ../../_images/mathmpl/math-b69eb39e09-2x.png 2x" style="position: relative; bottom: -2px"/> to

around fractions. Doing things the obvious way produces brackets that are too
small:</p>

</pre></div>
</div>
<div class="math notranslate nohighlight">
\[(\frac{5 - \frac{1}{x}}{4})\]</div>
<p>The solution is to precede the bracket with <code class="docutils literal notranslate"><span class="pre">\left</span></code> and <code class="docutils literal notranslate"><span class="pre">\right</span></code> to inform
the parser that those brackets encompass the entire object.:</p>

<section id="fonts">
<span id="mathtext-fonts"></span><h2>Fonts<a class="headerlink" href="#fonts" title="Permalink to this heading">#</a></h2>
<p>The default font is <em>italics</em> for mathematical symbols.</p>
<div class="admonition note">
<p class="admonition-title">Note</p>
<p>This default can be changed using <code class="docutils literal notranslate"><a class="reference internal" href="../introductory/customizing.html?highlight=mathtext.default#matplotlibrc-sample"><span class="std std-ref"><span class="pre">rcParams["mathtext.default"]</span></span></a></code> (default: <code class="docutils literal notranslate"><span class="pre">'it'</span></code>). This is
useful, for example, to use the same font as regular non-math text for math
text, by setting it to <code class="docutils literal notranslate"><span class="pre">regular</span></code>.</p>
</div>
<p>To change fonts, e.g., to write "sin" in a Roman font, enclose the text in a
font command:</p>
<div class="highlight-default notranslate"><div class="highlight"><pre><span></span><span class="sa">r</span><span class="s1">'$s(t) = \mathcal</span><span class="si">{A}</span><span class="s1">\mathrm</span><span class="si">{sin}</span><span class="s1">(2 \omega t)$'</span>
</pre></div>
</div>
<div class="math notranslate nohighlight">
\[s(t) = \mathcal{A}\mathrm{sin}(2 \omega t)\]</div>
<p>More conveniently, many commonly used function names that are typeset in
a Roman font have shortcuts. So the expression above could be written as
follows:</p>
<div class="highlight-default notranslate"><div class="highlight"><pre><span></span><span class="sa">r</span><span class="s1">'$s(t) = \mathcal</span><span class="si">{A}</span><span class="s1">\sin(2 \omega t)$'</span>
</pre></div>
</div>
<div class="math notranslate nohighlight">
\[s(t) = \mathcal{A}\sin(2 \omega t)\]</div>
<p>Here "s" and "t" are variable in italics font (default), "sin" is in Roman
font, and the amplitude "A" is in calligraphy font. Note in the example above
the calligraphy <code class="docutils literal notranslate"><span class="pre">A</span></code> is squished into the <code class="docutils literal notranslate"><span class="pre">sin</span></code>. You can use a spacing
command to add a little whitespace between them:</p>
<div class="highlight-default notranslate"><div class="highlight"><pre><span></span><span class="sa">r</span><span class="s1">'s(t) = \mathcal</span><span class="si">{A}</span><span class="s1">\/\sin(2 \omega t)'</span>
</pre></div>
</div>
<div class="math notranslate nohighlight">

<p>Additionally, you can use <code class="docutils literal notranslate"><span class="pre">\mathdefault{...}</span></code> or its alias
<code class="docutils literal notranslate"><span class="pre">\mathregular{...}</span></code> to use the font used for regular text outside of
mathtext. There are a number of limitations to this approach, most notably
that far fewer symbols will be available, but it can be useful to make math
expressions blend well with other text in the plot.</p>
<section id="custom-fonts">
<h3>Custom fonts<a class="headerlink" href="#custom-fonts" title="Permalink to this heading">#</a></h3>
<p>mathtext also provides a way to use custom fonts for math. This method is
fairly tricky to use, and should be considered an experimental feature for
patient users only. By setting <code class="docutils literal notranslate"><a class="reference internal" href="../introductory/customizing.html?highlight=mathtext.fontset#matplotlibrc-sample"><span class="std std-ref"><span class="pre">rcParams["mathtext.fontset"]</span></span></a></code> (default: <code class="docutils literal notranslate"><span class="pre">'dejavusans'</span></code>) to <code class="docutils literal notranslate"><span class="pre">custom</span></code>,
you can then set the following parameters, which control which font file to use
for a particular set of math characters.</p>

<p>Each parameter should be set to a fontconfig font descriptor (as defined in the
yet-to-be-written font chapter).</p>
<p>The fonts used should have a Unicode mapping in order to find any
non-Latin characters, such as Greek. If you want to use a math symbol
that is not contained in your custom fonts, you can set
<code class="docutils literal notranslate"><a class="reference internal" href="../introductory/customizing.html?highlight=mathtext.fallback#matplotlibrc-sample"><span class="std std-ref"><span class="pre">rcParams["mathtext.fallback"]</span></span></a></code> (default: <code class="docutils literal notranslate"><span class="pre">'cm'</span></code>) to either <code class="docutils literal notranslate"><span class="pre">'cm'</span></code>, <code class="docutils literal notranslate"><span class="pre">'stix'</span></code> or <code class="docutils literal notranslate"><span class="pre">'stixsans'</span></code>
which will cause the mathtext system to use
characters from an alternative font whenever a particular
character can not be found in the custom font.</p>
<p>Note that the math glyphs specified in Unicode have evolved over time, and many
fonts may not have glyphs in the correct place for mathtext.</p>
