Highcharts - manually trigger hover event on a point

Question

When you hover over a point in a Highcharts chart, you get a nice enlarged circle under you cursor (or other symbol). What I would like to do manually trigger that hover eff

Answer 1

Here is an example of how to select (hover) the last valid point in series programmatically:

  // Find last not-null point in data
  let last = data.indexOf(null) - 1;
  last = (last === -2) ? data.length - 1 : last;
  const lastPoint = this.series[0].points[last];

  // Trigger the hover event 
  lastPoint.setState('hover');
  lastPoint.state = '';  // You need this to fix hover bug
  this.tooltip.refresh(lastPoint); // Show tooltip
