+ *
+ * The Ext.chart package provides the capability to visualize data.
* Each chart binds directly to an Ext.data.Store enabling automatic updates of the chart.
- * To change the look and feel of a chart, see the {@link #chartStyle} and {@link #extraStyle} config options.
- * @constructor
- * @xtype chart
+ * A chart configuration object has some overall styling options as well as an array of axes
+ * and series. A chart instance example could look like:
+ *
+ <pre><code>
+ Ext.create('Ext.chart.Chart', {
+ renderTo: Ext.getBody(),
+ width: 800,
+ height: 600,
+ animate: true,
+ store: store1,
+ shadow: true,
+ theme: 'Category1',
+ legend: {
+ position: 'right'
+ },
+ axes: [ ...some axes options... ],
+ series: [ ...some series options... ]
+ });
+ </code></pre>
+ *
+ * In this example we set the `width` and `height` of the chart, we decide whether our series are
+ * animated or not and we select a store to be bound to the chart. We also turn on shadows for all series,
+ * select a color theme `Category1` for coloring the series, set the legend to the right part of the chart and
+ * then tell the chart to render itself in the body element of the document. For more information about the axes and
+ * series configurations please check the documentation of each series (Line, Bar, Pie, etc).
