+The 'chart' member must be set prior to rendering.</p>
+
+<p>A Mask can be used to select a certain region in a chart.
+When enabled, the <code>select</code> event will be triggered when a
+region is selected by the mask, allowing the user to perform
+other tasks like zooming on that region, etc.</p>
+
+<p>In order to use the mask one has to set the Chart <code>mask</code> option to
+<code>true</code>, <code>vertical</code> or <code>horizontal</code>. Then a possible configuration for the
+listener could be:</p>
+
+<pre class="prettyprint"><code> items: {
+ xtype: 'chart',
+ animate: true,
+ store: store1,
+ mask: 'horizontal',
+ listeners: {
+ select: {
+ fn: function(me, selection) {
+ me.setZoom(selection);
+ me.mask.hide();
+ }
+ }
+ },
+</code></pre>
+
+<p>In this example we zoom the chart to that particular region. You can also get
+a handle to a mask instance from the chart object. The <code>chart.mask</code> element is a
+<code>Ext.Panel</code>.</p>
