Getting values with the Chart.get() method

The Chart.get() method can be used to get an axis, series, or a point by its ID. It returns an object of an axis, series, or a point containing various properties. This method is useful due to faster access to the mentioned components, as we don't have to manually navigate through the object hierarchy of a chart.

Note

Note that this method is only available in the top-level chart object.

Consider the following example from Chapter 7, Theming with Highcharts, modified to include an ID for the Windows 7 data point:

$( '#chart_container' ).highcharts({
  chart: {
    type: 'pie'
  },
  title: {
    ...
  },
  tooltip: {
    ...
  },aotOptions: {
    ...
  },
  series: [{
    name: 'Windows versions',
    data: [
      {
        name: 'Win 7',
        id: 'win7',
        y: 55.03
      },
      ...
    ]
  }]
}

While being on the top-level chart object, we can call the get() method in the callback function to get the object of the win7 data point:

var win7Point...
