<p>Zooming and panning on any of the charts will zoom and pan all the
others. Selecting points on one will select points on the others.</p>
<p>To use this, source <a href="../extras/synchronizer.js"><code>extras/synchronizer.js</code></a>
on your page. See the comments in that file for usage. However, for better browser compatibility,
use the file from <tt>src-es5/extras/</tt> (<tt>dist/extras/</tt>) instead.</p>
