<p>This module defines default legend handlers.</p>
<p>It is strongly encouraged to have read the <a class="reference internal" href="../tutorials/intermediate/legend_guide.html"><span class="doc">legend guide</span></a> before this documentation.</p>
<p>Legend handlers are expected to be a callable object with a following
signature.</p>
<div class="highlight-default notranslate"><div class="highlight"><pre><span></span><span class="n">legend_handler</span><span class="p">(</span><span class="n">legend</span><span class="p">,</span> <span class="n">orig_handle</span><span class="p">,</span> <span class="n">fontsize</span><span class="p">,</span> <span class="n">handlebox</span><span class="p">)</span>
</pre></div>
<p>Where <em>legend</em> is the legend itself, <em>orig_handle</em> is the original
plot, <em>fontsize</em> is the fontsize in pixels, and <em>handlebox</em> is a
OffsetBox instance. Within the call, you should create relevant
artists (using relevant properties from the <em>legend</em> and/or
<em>orig_handle</em>) and add them into the handlebox. The artists needs to
be scaled according to the fontsize (note that the size is in pixel,
i.e., this is dpi-scaled value).</p>
<p>This module includes definition of several legend handler classes
derived from the base class (HandlerBase) with the following method:</p>
<div class="highlight-default notranslate"><div class="highlight"><pre><span></span><span class="k">def</span> <span class="nf">legend_artist</span><span class="p">(</span><span class="bp">self</span><span class="p">,</span> <span class="n">legend</span><span class="p">,</span> <span class="n">orig_handle</span><span class="p">,</span> <span class="n">fontsize</span><span class="p">,</span> <span class="n">handlebox</span><span class="p">)</span>

<dd><p>A Base class for default legend handlers.</p>
<p>The derived classes are meant to override <em>create_artists</em> method, which
has a following signature.:</p>
<div class="highlight-default notranslate"><div class="highlight"><pre><span></span><span class="k">def</span> <span class="nf">create_artists</span><span class="p">(</span><span class="bp">self</span><span class="p">,</span> <span class="n">legend</span><span class="p">,</span> <span class="n">orig_handle</span><span class="p">,</span>

                   <span class="n">trans</span><span class="p">):</span>
</pre></div>
<p>The overridden method needs to create artists of the given
transform that fits in the given dimension (xdescent, ydescent,
width, height) that are scaled by fontsize if necessary.</p>
