Highmaps drill down map select event

Question

I managed to create a map of Norway using 'Highmaps' (http://www.highcharts.com/maps/demo) with Counties and when it select a county it will drill down to the municipalities. I need to catch the select event in the drill down and display some data according to the municipality. But could not find any events for drilldown.

Any Ideas?

Answer 1

I figured it out with the help of Highcharts helpdesk support. Here is the fiddle http://jsfiddle.net/bydfsxe2/

// Set drilldown pointers
$.each(data, function (i) {
    this.drilldown = this.properties['hc-key'];
    this.value = i; // Non-random bogus data
});

// Instanciate the map
Highcharts.mapChart('container', {
    chart: {
        events: {
            drilldown: function (e) {
//call external function
                                    alert(e.point.drilldown);
//rest of the code
