Ext.chart.axis.Abstract
Ext.chart.axis.Axis

Defines axis for charts. The axis position, type, style can be configured. The axes are defined in an axes array of configuration objects where the type, field, grid and other configuration options can be set. To know more about how to create a Chart please check the Chart class documentation. Here's an example for the axes part: An example of axis for a series (in this case for an area chart that has multiple layers of yFields) could be:

axes: [{
    type: 'Numeric',
    grid: true,
    position: 'left',
    fields: ['data1', 'data2', 'data3'],
    title: 'Number of Hits',
    grid: {
        odd: {
            opacity: 1,
            fill: '#ddd',
            stroke: '#bbb',
            'stroke-width': 1
        }
    },
    minimum: 0
}, {
    type: 'Category',
    position: 'bottom',
    fields: ['name'],
    title: 'Month of the Year',
    grid: true,
    label: {
        rotate: {
            degrees: 315
        }
    }
}]

In this case we use a Numeric axis for displaying the values of the Area series and a Category axis for displaying the names of the store elements. The numeric axis is placed on the left of the screen, while the category axis is placed at the bottom of the chart. Both the category and numeric axes have grid set, which means that horizontal and vertical lines will cover the chart background. In the category axis the labels will be rotated so they can fit the space better.
