<p>This tutorial aims to show the beginning, middle, and end of a single
visualization using Matplotlib. We'll begin with some raw data and
end by saving a figure of a customized visualization. Along the way we try
to highlight some neat features and best-practices using Matplotlib.</p>
<div class="admonition note">
<p class="admonition-title">Note</p>
<p>This tutorial is based on
<a class="reference external" href="https://pbpython.com/effective-matplotlib.html">this excellent blog post</a>

<section id="a-note-on-the-explicit-vs-implicit-interfaces">
<h2>A note on the explicit vs. implicit interfaces<a class="headerlink" href="#a-note-on-the-explicit-vs-implicit-interfaces" title="Permalink to this heading">#</a></h2>
<p>Matplotlib has two interfaces. For an explanation of the trade-offs between the
explicit and implicit interfaces see <a class="reference internal" href="../../users/explain/api_interfaces.html#api-interfaces"><span class="std std-ref">Matplotlib Application Interfaces (APIs)</span></a>.</p>
<p>In the explicit object-oriented (OO) interface we directly utilize instances of
<a class="reference internal" href="../../api/axes_api.html#matplotlib.axes.Axes" title="matplotlib.axes.Axes"><code class="xref py py-class docutils literal notranslate"><span class="pre">axes.Axes</span></code></a> to build up the visualization in an instance of
<a class="reference internal" href="../../api/figure_api.html#matplotlib.figure.Figure" title="matplotlib.figure.Figure"><code class="xref py py-class docutils literal notranslate"><span class="pre">figure.Figure</span></code></a>. In the implicit interface, inspired by and modeled on
MATLAB, we use a global state-based interface which is encapsulated in the
<a class="reference internal" href="../../api/pyplot_summary.html#module-matplotlib.pyplot" title="matplotlib.pyplot"><code class="xref py py-mod docutils literal notranslate"><span class="pre">pyplot</span></code></a> module to plot to the "current Axes". See the <a class="reference internal" href="pyplot.html"><span class="doc">pyplot
tutorials</span></a> for a more in-depth look at the
pyplot interface.</p>
<p>Most of the terms are straightforward but the main thing to remember
is that:</p>
<ul class="simple">
<li><p>The <a class="reference internal" href="../../api/figure_api.html#matplotlib.figure.Figure" title="matplotlib.figure.Figure"><code class="xref py py-obj docutils literal notranslate"><span class="pre">Figure</span></code></a> is the final image, and may contain one or more <a class="reference internal" href="../../api/axes_api.html#matplotlib.axes.Axes" title="matplotlib.axes.Axes"><code class="xref py py-obj docutils literal notranslate"><span class="pre">Axes</span></code></a>.</p></li>
<li><dl class="simple">
<dt>The <a class="reference internal" href="../../api/axes_api.html#matplotlib.axes.Axes" title="matplotlib.axes.Axes"><code class="xref py py-obj docutils literal notranslate"><span class="pre">Axes</span></code></a> represents an individual plot (not to be confused with</dt><dd><p><a class="reference internal" href="../../api/axis_api.html#matplotlib.axis.Axis" title="matplotlib.axis.Axis"><code class="xref py py-obj docutils literal notranslate"><span class="pre">Axis</span></code></a>, which refers to the x/y axis of a plot).</p>
</dd>
</dl>
</li>
</ul>
<p>We call methods that do the plotting directly from the Axes, which gives
us much more flexibility and power in customizing our plot.</p>
<div class="admonition note">
<p class="admonition-title">Note</p>
<p>In general, use the explicit interface over the implicit pyplot interface
for plotting.</p>

<h2>Getting started<a class="headerlink" href="#getting-started" title="Permalink to this heading">#</a></h2>
<p>This data is naturally visualized as a barplot, with one bar per
group. To do this with the object-oriented approach, we first generate
an instance of <a class="reference internal" href="../../api/figure_api.html#matplotlib.figure.Figure" title="matplotlib.figure.Figure"><code class="xref py py-class docutils literal notranslate"><span class="pre">figure.Figure</span></code></a> and
<a class="reference internal" href="../../api/axes_api.html#matplotlib.axes.Axes" title="matplotlib.axes.Axes"><code class="xref py py-class docutils literal notranslate"><span class="pre">axes.Axes</span></code></a>. The Figure is like a canvas, and the Axes
is a part of that canvas on which we will make a particular visualization.</p>

<p>For this function, the <code class="docutils literal notranslate"><span class="pre">x</span></code> argument is the original tick label and <code class="docutils literal notranslate"><span class="pre">pos</span></code>

<p>We can then apply this function to the labels on our plot. To do this,
we use the <code class="docutils literal notranslate"><span class="pre">xaxis</span></code> attribute of our axes. This lets you perform
