<dd><p>Draws a collection of paths selecting drawing properties from
the lists <em>facecolors</em>, <em>edgecolors</em>, <em>linewidths</em>,
<em>linestyles</em> and <em>antialiaseds</em>. <em>offsets</em> is a list of
offsets to apply to each of the paths. The offsets in
<em>offsets</em> are first transformed by <em>offsetTrans</em> before being
applied. <em>offset_position</em> may be either “screen” or “data”
depending on the space that the offsets are in.</p>
<p>This provides a fallback implementation of
<a class="reference internal" href="#matplotlib.backends.backend_pdf.RendererPdf.draw_path_collection" title="matplotlib.backends.backend_pdf.RendererPdf.draw_path_collection"><code class="xref py py-meth docutils literal notranslate"><span class="pre">draw_path_collection()</span></code></a> that makes multiple calls to

Some backends may want to override this in
order to render each set of path data only once, and then
reference that path multiple times with the different offsets,
colors, styles etc. The generator methods
<code class="xref py py-meth docutils literal notranslate"><span class="pre">_iter_collection_raw_paths()</span></code> and
<code class="xref py py-meth docutils literal notranslate"><span class="pre">_iter_collection()</span></code> are provided to help with (and
standardize) the implementation across backends. It is highly
recommended to use those generators, so that changes to the
behavior of <a class="reference internal" href="#matplotlib.backends.backend_pdf.RendererPdf.draw_path_collection" title="matplotlib.backends.backend_pdf.RendererPdf.draw_path_collection"><code class="xref py py-meth docutils literal notranslate"><span class="pre">draw_path_collection()</span></code></a> can be made globally.</p>

<p><strong>backend implementers note</strong></p>
<p>When you are trying to determine if you have gotten your bounding box
right (which is what enables the text layout/alignment to work
properly), it helps to change the line in text.py:</p>
<div class="highlight-default notranslate"><div class="highlight"><pre><span></span><span class="k">if</span> <span class="mi">0</span><span class="p">:</span> <span class="n">bbox_artist</span><span class="p">(</span><span class="bp">self</span><span class="p">,</span> <span class="n">renderer</span><span class="p">)</span>
</pre></div>
</div>
<p>to if 1, and then the actual bounding box will be plotted along with
your text.</p>
