Ext.chart.axis.AbstractExt.chart.axis.AxisExt.chart.axis.Numeric
An axis to handle numeric values. This axis is used for quantitative data as +opposed to the category axis. You can set mininum and maximum values to the +axis so that the values are bound to that. If no values are set, then the +scale will auto-adjust to the values.
+ +
For example:
+ +var store = Ext.create('Ext.data.JsonStore', {
+ fields: ['name', 'data1', 'data2', 'data3', 'data4', 'data5'],
+ data: [
+ {'name':'metric one', 'data1':10, 'data2':12, 'data3':14, 'data4':8, 'data5':13},
+ {'name':'metric two', 'data1':7, 'data2':8, 'data3':16, 'data4':10, 'data5':3},
+ {'name':'metric three', 'data1':5, 'data2':2, 'data3':14, 'data4':12, 'data5':7},
+ {'name':'metric four', 'data1':2, 'data2':14, 'data3':6, 'data4':1, 'data5':23},
+ {'name':'metric five', 'data1':27, 'data2':38, 'data3':36, 'data4':13, 'data5':33}
+ ]
+});

+Ext.create('Ext.chart.Chart', {
+ renderTo: Ext.getBody(),
+ width: 500,
+ height: 300,
+ store: store,
+ axes: [{

+ fields: ['data1', 'data2', 'data3', 'data4', 'data5'],
+ title: 'Sample Values',
+ grid: {

+ stroke: '#bbb',
+ 'stroke-width': 1

+ minimum: 0,

+});
+In this example we create an axis of Numeric type. We set a minimum value so that +even if all series have values greater than zero, the grid starts at zero. We bind +the axis onto the left part of the surface by setting position to left. +We bind three different store fields to this axis by setting fields to an array. +We set the title of the axis to Number of Hits by using the title property. +We use a grid configuration to set odd background rows to a certain style and even rows +to be transparent/ignored.
