<p>Draw a colorbar in an existing axes.</p>
<p>This is a base class for the <a class="reference internal" href="#matplotlib.colorbar.Colorbar" title="matplotlib.colorbar.Colorbar"><code class="xref py py-class docutils literal"><span class="pre">Colorbar</span></code></a> class, which is the
basis for the <a class="reference internal" href="pyplot_api.html#matplotlib.pyplot.colorbar" title="matplotlib.pyplot.colorbar"><code class="xref py py-func docutils literal"><span class="pre">colorbar()</span></code></a> function and the
<a class="reference internal" href="figure_api.html#matplotlib.figure.Figure.colorbar" title="matplotlib.figure.Figure.colorbar"><code class="xref py py-meth docutils literal"><span class="pre">colorbar()</span></code></a> method, which are the
usual ways of creating a colorbar.</p>
<p>It is also useful by itself for showing a colormap. If the <em>cmap</em>
kwarg is given but <em>boundaries</em> and <em>values</em> are left as None,
then the colormap will be displayed on a 0-1 scale. To show the
under- and over-value colors, specify the <em>norm</em> as:</p>
<div class="highlight-default"><div class="highlight"><pre><span></span><span class="n">colors</span><span class="o">.</span><span class="n">Normalize</span><span class="p">(</span><span class="n">clip</span><span class="o">=</span><span class="kc">False</span><span class="p">)</span>
</pre></div>
</div>
<p>To show the colors versus index instead of on the 0-1 scale,
use:</p>
<div class="highlight-default"><div class="highlight"><pre><span></span><span class="n">norm</span><span class="o">=</span><span class="n">colors</span><span class="o">.</span><span class="n">NoNorm</span><span class="o">.</span>
