In many scenarios, you would like to group data by more than one field. In the examples depicted in the earlier recipes, the browser adoption data was grouped by year. Now, this data can be grouped by platform as well. For example, adoption of the Chrome browser in the year 2012 on the Windows platform can be accomplished by adding multiple axes to the chart.

series: [{
    name: 'On Windows',
    data: ['15', '26', '40', '52', '56'],
    type: 'column',
}, {
    name: 'On Linux',
    data: ['8', '15', '28', '32', '38'],
    type: 'column',
}, {
    name: 'On Mac',
    data: ['12', '20', '33', '40', '45'],
    type: 'area'
}, {
    name: 'On Others',
    data: ['2', '8', '15', '18', '22'],
    type: 'area'
}]
