Implementation of highcharts.destroy() and highcharts.update() functions

[fervanrijswijk]

Highcharts has functions to update and destroy a chart. When data changes every few seconds, the chart can be updated instead of created over and over again without the ability of being destroyed.

I would like to be able to do one of the things below to prevent memory leaks.

private createHighchart (options: HighchartOptions): void {
    if(this.chart) {
      this.chart.update(options);
    }
    else {
      this.chart = new Highchart(options);
    }
  }

private createHighchart (options: HighchartOptions): void {
    if(this.chart) {
      this.chart.destroy();
    }
    else {
      this.chart = new Highchart(options);
    }
  }

@fervanrijswijk its possible: try to use this.chart.ref. This is a reference to the original highcharts object.
