2 </span> * @class Ext.chart.series.Column
3 * @extends Ext.chart.series.Bar
5 * Creates a Column Chart. Much of the methods are inherited from Bar. A Column Chart is a useful visualization technique to display quantitative information for different
6 * categories that can show some progression (or regression) in the data set.
7 * As with all other series, the Column Series must be appended in the *series* Chart array configuration. See the Chart
8 * documentation for more information. A typical configuration object for the column series could be:
10 * {@img Ext.chart.series.Column/Ext.chart.series.Column.png Ext.chart.series.Column chart series
14 * var store = Ext.create('Ext.data.JsonStore', {
15 * fields: ['name', 'data1', 'data2', 'data3', 'data4', 'data5'],
17 * {'name':'metric one', 'data1':10, 'data2':12, 'data3':14, 'data4':8, 'data5':13},
18 * {'name':'metric two', 'data1':7, 'data2':8, 'data3':16, 'data4':10, 'data5':3},
19 * {'name':'metric three', 'data1':5, 'data2':2, 'data3':14, 'data4':12, 'data5':7},
20 * {'name':'metric four', 'data1':2, 'data2':14, 'data3':6, 'data4':1, 'data5':23},
21 * {'name':'metric five', 'data1':27, 'data2':38, 'data3':36, 'data4':13, 'data5':33}
25 * Ext.create('Ext.chart.Chart', {
26 * renderTo: Ext.getBody(),
36 * renderer: Ext.util.Format.numberRenderer('0,0')
38 * title: 'Sample Values',
45 * title: 'Sample Metrics'
52 * renderer: Ext.util.Format.numberRenderer('0,0')
54 * title: 'Sample Values',
61 * title: 'Sample Metrics'
71 * renderer: function(storeItem, item) {
72 * this.setTitle(storeItem.get('name') + ': ' + storeItem.get('data1') + ' $');
76 * display: 'insideEnd',
77 * 'text-anchor': 'middle',
79 * renderer: Ext.util.Format.numberRenderer('0'),
80 * orientation: 'vertical',
88 * In this configuration we set `column` as the series type, bind the values of the bars to the bottom axis, set `highlight` to true so that bars are smoothly highlighted
89 * when hovered and bind the `xField` or category field to the data store `name` property and the `yField` as the data1 property of a store element.
