[Solved]-Pie chart labels - dynamic position (distance)-Highcharts

you can for example use chart.load event and change distance, x or y properties for an individual point. for example:

events: {
  load: function() {
    this.series[0].points.foreach(point => {
      if (point.y > 5) {
        point.update({
          datalabels: {
            distance: -50
          }
          // avoid redraw after each update
        }, false);
      }
    });
    this.redraw();
  }
}
