Question

I have Drilled the “Column chart”.
& Now I want to Drill down the “Pie chart”

my code for showing Pie chart is as below,

$(function () {
    var chart;
    $(document).ready(function() {
        chart = new Highcharts.Chart({
            chart: {
                renderTo: 'container',

            },
            title: {
                text: ''
            },
            tooltip: {
                pointFormat: '{series.name}: <b>{point.percentage}%</b>',
                percentageDecimals: 1
            },
            plotOptions: {
                pie: {
                    allowPointSelect: true,
                    cursor: 'pointer',
                    dataLabels: {
                        enabled: true,
                        color: '#000000',
                        connectorColor: '#000000',
                        formatter: function() {
                            return '<b>'+ this.point.name +'</b>: '+ Math.round(this.percentage) +' %';
                        }
                    }
                }
            },
            series: 
                [{
                   type:'pie',
                    data: model.mixchart

                }]
});
});

});

How can I do drilldown in this ?

After Drilldown It should show the Pie chart only. So what should I do for that in the code abve?

At least just Give me some reference links for drilldown in Pie chart so that I can Prefer that one.
