<p>
As of 4th December 2010 the code that produces the keys has been rewritten. There are two variants of keys available,
a horizontal one designed to sit in the gutter, and a vertical one that is designed to sit on top of (ie over) the chart.
</p>
<p>
The actual positioning is now configurable though, so you could have a horizontal key and position it to sit on top
of the chart.
</p>
<h4>Key properties</h4>
<p>
The available key properties and their defaults are listed below (some chart types have slightly different defaults to
suit):
</p>
<ul>
<li>chart.key (<i>[] (An empty array)</i>)</li>
<li>chart.key.position (<i>graph</i>)</li>
<li>chart.key.position.gutter.boxed (<i>true</i>)</li>
<li>chart.key.position.x (<i>null</i>)</li>
<li>chart.key.position.y (<i>null</i>)</li>
<li>chart.key.shadow (<i>false</i>)</li>
<li>chart.key.shadow.offsetx (<i>2</i>)</li>
<li>chart.key.shadow.offsety (<i>2</i>)</li>
<li>chart.key.shadow.color (<i>#666</i>)</li>
<li>chart.key.shadow.blur (<i>3</i>)</li>
<li>chart.key.color.shape (<i>square</i>)</li>
<li>chart.key.background (<i>white</i>)</li>
<li>chart.key.rounded (<i>true</i>)</li>
<li>chart.key.text.size (<i>10</i>)</li>
</ul>
<h4>Interactive keys</h4>
<p>
The Line chart supports interactive keys - as shown in the example. This is only available when the key
is in <i>graph</i> mode. This allows you to click a key item and it will be highlighted on the chart.
