</span> * Creates a Bar Chart. A Bar Chart is a useful visualization technique to display quantitative information for
 * different categories that can show some progression (or regression) in the dataset. As with all other series, the Bar
 * Series must be appended in the *series* Chart array configuration. See the Chart documentation for more information.
 * A typical configuration object for the bar series could be:
 *
 *     @example
 *     var store = Ext.create('Ext.data.JsonStore', {
 *         fields: ['name', 'data'],
 *         data: [
 *             { 'name': 'metric one',   'data':10 },
 *             { 'name': 'metric two',   'data': 7 },
 *             { 'name': 'metric three', 'data': 5 },
 *             { 'name': 'metric four',  'data': 2 },
 *             { 'name': 'metric five',  'data':27 }
 *         ]
 *     });
 *
 *     Ext.create('Ext.chart.Chart', {
 *         renderTo: Ext.getBody(),
 *         width: 500,
 *         height: 300,
 *         animate: true,
 *         store: store,
 *         axes: [{
 *             type: 'Numeric',
 *             position: 'bottom',
 *             fields: ['data'],
 *             label: {
 *                 renderer: Ext.util.Format.numberRenderer('0,0')
 *             },
 *             title: 'Sample Values',
 *             grid: true,
 *             minimum: 0
 *         }, {
 *             type: 'Category',
 *             position: 'left',
 *             fields: ['name'],
 *             title: 'Sample Metrics'
 *         }],
 *         series: [{
 *             type: 'bar',
 *             axis: 'bottom',
 *             highlight: true,
 *             tips: {
 *               trackMouse: true,
 *               width: 140,
 *               height: 28,
 *               renderer: function(storeItem, item) {
 *                 this.setTitle(storeItem.get('name') + ': ' + storeItem.get('data') + ' views');
 *               }
 *             },
 *             label: {
 *               display: 'insideEnd',
 *                 field: 'data',
 *                 renderer: Ext.util.Format.numberRenderer('0'),
 *                 orientation: 'horizontal',
 *                 color: '#333',
 *                 'text-anchor': 'middle'
 *             },
 *             xField: 'name',
 *             yField: 'data'
 *         }]
 *     });
 *
 * In this configuration we set `bar` as the series type, bind the values of the bar to the bottom axis and set the
 * xField or category field to the `name` parameter of the store. We also set `highlight` to true which enables smooth
 * animations when bars are hovered. We also set some configuration for the bar labels to be displayed inside the bar,
 * to display the information found in the `data1` property of each element store, to render a formated text with the
 * `Ext.util.Format` we pass in, to have an `horizontal` orientation (as opposed to a vertical one) and we also set
 * other styles like `color`, `text-anchor`, etc.
