<h1>Text introduction<a class="headerlink" href="#text-introduction" title="Permalink to this headline">¶</a></h1>

Introduction to plotting and working with text in Matplotlib.

Matplotlib has extensive text support, including support for

mathematical expressions, truetype support for raster and

vector outputs, newline separated text with arbitrary

rotations, and unicode support.

Because it embeds fonts directly in output documents, e.g., for postscript

or PDF, what you see on the screen is what you get in the hardcopy.

<a class="reference external" href="https://www.freetype.org/">FreeType</a> support

produces very nice, antialiased fonts, that look good even at small

raster sizes. matplotlib includes its own

<a class="reference internal" href="../../api/font_manager_api.html#module-matplotlib.font_manager" title="matplotlib.font_manager"><code class="xref py py-mod docutils literal">matplotlib.font_manager</code></a> (thanks to Paul Barrett), which

implements a cross platform, <code class="xref py py-obj docutils literal">W3C</code>

compliant font finding algorithm.

The user has a great deal of control over text properties (font size, font

weight, text location and color, etc.) with sensible defaults set in

the <code class="xref py py-obj docutils literal">rc file</code>.

And significantly, for those interested in mathematical

or scientific figures, matplotlib implements a large number of TeX

math symbols and commands, supporting <a class="reference internal" href="mathtext.html#sphx-glr-tutorials-text-mathtext-py">mathematical expressions</a> anywhere in your figure.

</div>

<h1>Basic text commands<a class="headerlink" href="#basic-text-commands" title="Permalink to this headline">¶</a></h1>

The following commands are used to create text in the pyplot

interface

<ul>

<li><a class="reference internal" href="../../api/_as_gen/matplotlib.pyplot.text.html#matplotlib.pyplot.text" title="matplotlib.pyplot.text"><code class="xref py py-func docutils literal">text()</code></a> - add text at an arbitrary location to the <code class="docutils literal">Axes</code>;

<a class="reference internal" href="../../api/_as_gen/matplotlib.axes.Axes.text.html#matplotlib.axes.Axes.text" title="matplotlib.axes.Axes.text"><code class="xref py py-meth docutils literal">matplotlib.axes.Axes.text()</code></a> in the API.

</li>

<li><a class="reference internal" href="../../api/_as_gen/matplotlib.pyplot.xlabel.html#matplotlib.pyplot.xlabel" title="matplotlib.pyplot.xlabel"><code class="xref py py-func docutils literal">xlabel()</code></a> - add a label to the x-axis;

<a class="reference internal" href="../../api/_as_gen/matplotlib.axes.Axes.set_xlabel.html#matplotlib.axes.Axes.set_xlabel" title="matplotlib.axes.Axes.set_xlabel"><code class="xref py py-meth docutils literal">matplotlib.axes.Axes.set_xlabel()</code></a> in the API.

</li>

<li><a class="reference internal" href="../../api/_as_gen/matplotlib.pyplot.ylabel.html#matplotlib.pyplot.ylabel" title="matplotlib.pyplot.ylabel"><code class="xref py py-func docutils literal">ylabel()</code></a> - add a label to the y-axis;

<a class="reference internal" href="../../api/_as_gen/matplotlib.axes.Axes.set_ylabel.html#matplotlib.axes.Axes.set_ylabel" title="matplotlib.axes.Axes.set_ylabel"><code class="xref py py-meth docutils literal">matplotlib.axes.Axes.set_ylabel()</code></a> in the API.

</li>

<li><a class="reference internal" href="../../api/_as_gen/matplotlib.pyplot.title.html#matplotlib.pyplot.title" title="matplotlib.pyplot.title"><code class="xref py py-func docutils literal">title()</code></a> - add a title to the <code class="docutils literal">Axes</code>;

<a class="reference internal" href="../../api/_as_gen/matplotlib.axes.Axes.set_title.html#matplotlib.axes.Axes.set_title" title="matplotlib.axes.Axes.set_title"><code class="xref py py-meth docutils literal">matplotlib.axes.Axes.set_title()</code></a> in the API.

</li>

<li><a class="reference internal" href="../../api/_as_gen/matplotlib.pyplot.figtext.html#matplotlib.pyplot.figtext" title="matplotlib.pyplot.figtext"><code class="xref py py-func docutils literal">figtext()</code></a> - add text at an arbitrary location to the <code class="docutils literal">Figure</code>;

<code class="xref py py-meth docutils literal">matplotlib.figure.Figure.text()</code> in the API.

</li>

<li><a class="reference internal" href="../../api/_as_gen/matplotlib.pyplot.suptitle.html#matplotlib.pyplot.suptitle" title="matplotlib.pyplot.suptitle"><code class="xref py py-func docutils literal">suptitle()</code></a> - add a title to the <code class="docutils literal">Figure</code>;

<code class="xref py py-meth docutils literal">matplotlib.figure.Figure.suptitle()</code> in the API.

</li>

<dt><a class="reference internal" href="../../api/_as_gen/matplotlib.pyplot.annotate.html#matplotlib.pyplot.annotate" title="matplotlib.pyplot.annotate"><code class="xref py py-func docutils literal">annotate()</code></a> - add an annotation, with</dt>

<dd>optional arrow, to the <code class="docutils literal">Axes</code> ; <a class="reference internal" href="../../api/_as_gen/matplotlib.axes.Axes.annotate.html#matplotlib.axes.Axes.annotate" title="matplotlib.axes.Axes.annotate"><code class="xref py py-meth docutils literal">matplotlib.axes.Axes.annotate()</code></a>

in the API.

</dd>

</dl>

</li>

</ul>

All of these functions create and return a

<a class="reference internal" href="../../api/text_api.html#matplotlib.text.Text" title="matplotlib.text.Text"><code class="xref py py-func docutils literal">matplotlib.text.Text()</code></a> instance, which can be configured with a

variety of font and other properties. The example below shows all of

these commands in action.

<div class="highlight-python"><div class="highlight"><pre>import matplotlib.pyplot as plt

fig = <a href="../../api/_as_gen/matplotlib.figure.figaspect.html#matplotlib.figure" title="View documentation for matplotlib.pyplot.figure">plt.figure</a>()

fig.suptitle('bold figure suptitle', fontsize=14, fontweight='bold')

ax = fig.add_subplot(111)

fig.subplots_adjust(top=0.85)

ax.set_title('axes title')

ax.set_xlabel('xlabel')

ax.set_ylabel('ylabel')

ax.text(3, 8, 'boxed italics text in data coords', style='italic',

bbox={'facecolor': 'red', 'alpha': 0.5, 'pad': 10})

ax.text(2, 6, r'an equation: $E=mc^2$', fontsize=15)

ax.text(3, 2, u'unicode: Institut f\374r Festk\366rperphysik')
