+</span> * Charts provide a flexible way to achieve a wide range of data visualization capablitities.
+ * Each Chart gets its data directly from a {@link Ext.data.Store Store}, and automatically
+ * updates its display whenever data in the Store changes. In addition, the look and feel
+ * of a Chart can be customized using {@link Ext.chart.theme.Theme Theme}s.
+ *
+ * ## Creating a Simple Chart
+ *
+ * Every Chart has three key parts - a {@link Ext.data.Store Store} that contains the data,
+ * an array of {@link Ext.chart.axis.Axis Axes} which define the boundaries of the Chart,
+ * and one or more {@link Ext.chart.series.Series Series} to handle the visual rendering of the data points.
+ *
+ * ### 1. Creating a Store
+ *
+ * The first step is to create a {@link Ext.data.Model Model} that represents the type of
+ * data that will be displayed in the Chart. For example the data for a chart that displays
+ * a weather forecast could be represented as a series of "WeatherPoint" data points with
+ * two fields - "temperature", and "date":
+ *
+ * Ext.define('WeatherPoint', {
+ * extend: 'Ext.data.Model',
+ * fields: ['temperature', 'date']
+ * });
+ *
+ * Next a {@link Ext.data.Store Store} must be created. The store contains a collection of "WeatherPoint" Model instances.
+ * The data could be loaded dynamically, but for sake of ease this example uses inline data:
+ *
+ * var store = Ext.create('Ext.data.Store', {
+ * model: 'WeatherPoint',
+ * data: [
+ * { temperature: 58, date: new Date(2011, 1, 1, 8) },
+ * { temperature: 63, date: new Date(2011, 1, 1, 9) },
+ * { temperature: 73, date: new Date(2011, 1, 1, 10) },
+ * { temperature: 78, date: new Date(2011, 1, 1, 11) },
+ * { temperature: 81, date: new Date(2011, 1, 1, 12) }
+ * ]
+ * });
+ *
+ * For additional information on Models and Stores please refer to the [Data Guide](#/guide/data).
+ *
+ * ### 2. Creating the Chart object
+ *
+ * Now that a Store has been created it can be used in a Chart:
+ *
+ * Ext.create('Ext.chart.Chart', {
+ * renderTo: Ext.getBody(),
+ * width: 400,
+ * height: 300,
+ * store: store
+ * });
+ *
+ * That's all it takes to create a Chart instance that is backed by a Store.
+ * However, if the above code is run in a browser, a blank screen will be displayed.
+ * This is because the two pieces that are responsible for the visual display,
+ * the Chart's {@link #cfg-axes axes} and {@link #cfg-series series}, have not yet been defined.
+ *
+ * ### 3. Configuring the Axes
+ *
+ * {@link Ext.chart.axis.Axis Axes} are the lines that define the boundaries of the data points that a Chart can display.
+ * This example uses one of the most common Axes configurations - a horizontal "x" axis, and a vertical "y" axis:
+ *
+ * Ext.create('Ext.chart.Chart', {
+ * ...
+ * axes: [
+ * {
+ * title: 'Temperature',
+ * type: 'Numeric',
+ * position: 'left',
+ * fields: ['temperature'],
+ * minimum: 0,
+ * maximum: 100
+ * },
+ * {
+ * title: 'Time',
+ * type: 'Time',
+ * position: 'bottom',
+ * fields: ['date'],
+ * dateFormat: 'ga'
+ * }
+ * ]
+ * });
+ *
+ * The "Temperature" axis is a vertical {@link Ext.chart.axis.Numeric Numeric Axis} and is positioned on the left edge of the Chart.
+ * It represents the bounds of the data contained in the "WeatherPoint" Model's "temperature" field that was
+ * defined above. The minimum value for this axis is "0", and the maximum is "100".
+ *
+ * The horizontal axis is a {@link Ext.chart.axis.Time Time Axis} and is positioned on the bottom edge of the Chart.
+ * It represents the bounds of the data contained in the "WeatherPoint" Model's "date" field.
+ * The {@link Ext.chart.axis.Time#cfg-dateFormat dateFormat}
+ * configuration tells the Time Axis how to format it's labels.
+ *
+ * Here's what the Chart looks like now that it has its Axes configured:
+ *
+ * {@img Ext.chart.Chart/Ext.chart.Chart1.png Chart Axes}
+ *
+ * ### 4. Configuring the Series
+ *
+ * The final step in creating a simple Chart is to configure one or more {@link Ext.chart.series.Series Series}.
+ * Series are responsible for the visual representation of the data points contained in the Store.
+ * This example only has one Series:
+ *
+ * Ext.create('Ext.chart.Chart', {
+ * ...
+ * axes: [
+ * ...
+ * ],
+ * series: [
+ * {
+ * type: 'line',
+ * xField: 'date',
+ * yField: 'temperature'
+ * }
+ * ]
+ * });
+ *
+ * This Series is a {@link Ext.chart.series.Line Line Series}, and it uses the "date" and "temperature" fields
+ * from the "WeatherPoint" Models in the Store to plot its data points:
+ *
+ * {@img Ext.chart.Chart/Ext.chart.Chart2.png Line Series}
+ *
+ * See the [Simple Chart Example](doc-resources/Ext.chart.Chart/examples/simple_chart/index.html) for a live demo.
+ *
+ * ## Themes
+ *
+ * The color scheme for a Chart can be easily changed using the {@link #cfg-theme theme} configuration option:
+ *
+ * Ext.create('Ext.chart.Chart', {
+ * ...
+ * theme: 'Green',
+ * ...
+ * });
+ *
+ * {@img Ext.chart.Chart/Ext.chart.Chart3.png Green Theme}
+ *
+ * For more information on Charts please refer to the [Drawing and Charting Guide](#/guide/drawing_and_charting).
