An array of data points for the series. For the timeline series type, points can be given with three general parameters, name, label, and description:


series: [{
   type: 'timeline',
   data: [{
       name: 'Jan 2018',
       label: 'Some event label',
       description: 'Description to show in tooltip'

If all points additionally have the x values, and xAxis type is set to datetime, then events are laid out on a true time axis, where their placement reflects the actual time between them.
