<p>A module for dealing with the polylines used throughout Matplotlib.</p>
<p>The primary class for polyline handling in Matplotlib is <a class="reference internal" href="#matplotlib.path.Path" title="matplotlib.path.Path"><code class="xref py py-obj docutils literal notranslate"><span class="pre">Path</span></code></a>. Almost all

<p>Whilst a <a class="reference internal" href="#matplotlib.path.Path" title="matplotlib.path.Path"><code class="xref py py-obj docutils literal notranslate"><span class="pre">Path</span></code></a> instance itself cannot be drawn, some <a class="reference internal" href="artist_api.html#matplotlib.artist.Artist" title="matplotlib.artist.Artist"><code class="xref py py-obj docutils literal notranslate"><span class="pre">Artist</span></code></a> subclasses,

<dl class="docutils">
<dt>The underlying storage is made up of two parallel numpy arrays:</dt>
<dd><ul class="first last simple">
<li><em>vertices</em>: an Nx2 float array of vertices</li>
<li><em>codes</em>: an N-length uint8 array of vertex types</li>
</ul>
</dd>
</dl>
<p>These two arrays always have the same length in the first
dimension. For example, to represent a cubic curve, you must
provide three vertices as well as three codes <code class="docutils literal notranslate"><span class="pre">CURVE3</span></code>.</p>
<p>The code types are:</p>
<blockquote>
<div><ul class="simple">
<li><dl class="first docutils">
<dt><code class="docutils literal notranslate"><span class="pre">STOP</span></code> <span class="classifier-delimiter">:</span> <span class="classifier">1 vertex (ignored)</span></dt>

<p>Users of Path objects should not access the vertices and codes
arrays directly. Instead, they should use <a class="reference internal" href="#matplotlib.path.Path.iter_segments" title="matplotlib.path.Path.iter_segments"><code class="xref py py-meth docutils literal notranslate"><span class="pre">iter_segments()</span></code></a>
or <a class="reference internal" href="#matplotlib.path.Path.cleaned" title="matplotlib.path.Path.cleaned"><code class="xref py py-meth docutils literal notranslate"><span class="pre">cleaned()</span></code></a> to get the vertex/code pairs. This is important,
