Highcharts : Chart with drilldown how to obtain click event of drill up button

Question

I am using Highcharts wtih drilldown and here is my working FIDDLE.

How can I get the click event of the drill up button ? I have referred the Highcharts API but can't figure out how can I incorporate this into my code.

I want to do something like:

drillUp: function(){
     //get point details by using something like this or this.point
     //get series details by using something like point.series
}

You need to catch the event. See the chart.events.drillup API doc. To get the series and points in the series you would do something like:

    events: {
        drillup: function (e) {
            console.log(this);
            console.log(this.options.series[0].name);
            console.log(this.options.series[0].data[0].name);
        }
    }

Since you did not state which series or points you wanted this is the most general method.
