2 * @class Ext.chart.series.Column
3 * @extends Ext.chart.series.Bar
6 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
7 categories that can show some progression (or regression) in the data set.
8 As with all other series, the Column Series must be appended in the *series* Chart array configuration. See the Chart
9 documentation for more information. A typical configuration object for the column series could be:

14 fields: ['name', 'data1', 'data2', 'data3', 'data4', 'data5'],
16 {'name':'metric one', 'data1':10, 'data2':12, 'data3':14, 'data4':8, 'data5':13},
17 {'name':'metric two', 'data1':7, 'data2':8, 'data3':16, 'data4':10, 'data5':3},
18 {'name':'metric three', 'data1':5, 'data2':2, 'data3':14, 'data4':12, 'data5':7},
19 {'name':'metric four', 'data1':2, 'data2':14, 'data3':6, 'data4':1, 'data5':23},
20 {'name':'metric five', 'data1':27, 'data2':38, 'data3':36, 'data4':13, 'data5':33}

89 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
90 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.
