HighchartExport - Calculated column data (Extra data)

HighchartExport-ExtraInfo.js

// If we want to export some more info or calculated column in export csv data
// we can create a fake series with minimal required props and then push to chart.series
// and highchart will export that.

var s = {
  name: "Test2",
  options: {
    stickyTracking: true
  },
  points: [{
    name: 'Jan',
    x: 'Jan',
    y: 10
  }, {
    name: 'Feb',
    x: 'Jan',
    y: 10
  }, {
    name: 'Mar',
    x: 'Jan',
    y: 10
  }]
};

chart.series.push(s);
// That's it.
