<p>Draw a colorbar in an existing axes.</p>
<p>There are only some rare cases in which you would work directly with a
<a class="reference internal" href="#matplotlib.colorbar.ColorbarBase" title="matplotlib.colorbar.ColorbarBase"><code class="xref py py-obj docutils literal notranslate"><span class="pre">ColorbarBase</span></code></a> as an end-user. Typically, colorbars are used
with <a class="reference internal" href="cm_api.html#matplotlib.cm.ScalarMappable" title="matplotlib.cm.ScalarMappable"><code class="xref py py-obj docutils literal notranslate"><span class="pre">ScalarMappable</span></code></a>s such as an <a class="reference internal" href="image_api.html#matplotlib.image.AxesImage" title="matplotlib.image.AxesImage"><code class="xref py py-obj docutils literal notranslate"><span class="pre">AxesImage</span></code></a> generated via

For these cases you will use <a class="reference internal" href="#matplotlib.colorbar.Colorbar" title="matplotlib.colorbar.Colorbar"><code class="xref py py-obj docutils literal notranslate"><span class="pre">Colorbar</span></code></a> and
likely create it via <a class="reference internal" href="_as_gen/matplotlib.pyplot.colorbar.html#matplotlib.pyplot.colorbar" title="matplotlib.pyplot.colorbar"><code class="xref py py-obj docutils literal notranslate"><span class="pre">pyplot.colorbar</span></code></a> or <a class="reference internal" href="figure_api.html#matplotlib.figure.Figure.colorbar" title="matplotlib.figure.Figure.colorbar"><code class="xref py py-obj docutils literal notranslate"><span class="pre">Figure.colorbar</span></code></a>.</p>
<p>The main application of using a <a class="reference internal" href="#matplotlib.colorbar.ColorbarBase" title="matplotlib.colorbar.ColorbarBase"><code class="xref py py-obj docutils literal notranslate"><span class="pre">ColorbarBase</span></code></a> explicitly is drawing
colorbars that are not associated with other elements in the figure, e.g.
when showing a colormap by itself.</p>
<p>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 notranslate"><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">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 notranslate"><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="p">()</span>
