trackByArea doesn't work with coloredarea type

[genzgd]

Pretty much what the title says. If I have a regular area chart I can capture a click event in the "area" plot by setting series.trackByArea to true. Using this plugin and the coloredarea bype, only clicks on the point actually fire the event.

Thanks for reporting the issue @genzgd

Workaorund:
Demo: https://jsfiddle.net/BlackLabel/tg58gc6x/238/
Plugin:

  Highcharts.seriesTypes.coloredarea.prototype.getGraphPath = function() {
    var series = this,
      graphPath = [],
      segmentPath,
      singlePoints = []; // used in drawTracker
    // Divide into segments and build graph and area paths

    Highcharts.seriesTypes.area.prototype.getGraphPath.call(this);

    // this.areaPath = [];
    Highcharts.each(series.segments, function(segment) {
      segmentPath = series.getSegmentPath(segment.points);
      // add the segment to the graph, or a single point for tracking
      if (segment.points.length > 1) {
        graphPath.push([segmentPath, segment.color]);
      } else {
        singlePoints.push(segment.points);
      }
    });

    // Record it for use in drawGraph and drawTracker, and return graphPath
    series.singlePoints = singlePoints;
    series.graphPath = graphPath;
    return graphPath;
  };
