[Solved]-How can I change highcharts events after the chart has been initialized-Highcharts

it's not supported to update plotoptions in real time. jsfiddle.

you can update one-series options in that way:

chart.series[0].update({
  point: {
    events: {
      mouseover: function() {
        $('#report').html('outer x: ' + this.x + ', y: ' + this.y);
      }
    }
  } 
});
