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.
