Highcharts Drilldown From Bar-->pie Or Bar-->column

I need to create a bar-chart with a pie-chart drill down. Everything works fine in all browsers but Do you need more explanations? function activities(params) { //params

Solution 1:

The problem was an error in high charts. I was running on 3.0.1 which caused the error, they switched to 3.0.2 2 days ago and the problem is fixed.

For anybody who is interested in a drill down-chart from bar to pie...here you can find the example.

And here is the code:

HTML:

<scriptsrc="http://code.highcharts.com/3.0.2/highcharts.js"></script><divid="activities_chart"style="width: 100%; height: 340px;"></div>

JS:

$(function () {

var title_activities = "Activities",
    source_activities = "My source",
    link_activities = "http://www.highcharts.com",
    credits_databasis_str_activities = "215",
    activities_category_names = ["eat", "read", "surf in internet"],
    activities_category_data = [{y:66.15, drilldown:{name:"eat - How often?", data:[["1 time per day", 21], ["3 times per day", 45], ["2 times per day", 27], ["2 times a week", 3], ["≥ 3 times a week", 5], ["less", 4], ["every other week", 3], ["1 times a week", 7], ["not specified", 6], ["once a month", 6]]}}, {y:67.71, drilldown:{name:"read - How much time?", data:[["2h per day", 11], ["1h per day", 41], ["less often", 6], ["2h per week", 8], ["1/2h per day", 38], ["1h per week", 10], ["3h per week", 4], ["≥ 3h per day", 5], ["not specified", 7]]}}, {y:59.38, drilldown:{name:"surf in internet - How much time?", data:[["2h per day", 31], ["1h per week", 1], ["2h per week", 2], ["1h per day", 37], ["1/2h per day", 20], ["≥ 3h per day", 13], ["less often", 3], ["not specified", 5], ["3h per week", 2]]}}],
    room_filter_name = "Living Room"var colors = Highcharts.getOptions().colors,
        categories = activities_category_names,
        name = 'Activities',
        data = activities_category_data

function setChart(chart, options) {

        var max = chart.series.length;
        for (var i = 0; i < max; i++) {
          chart.series[0].remove(false);
        }

        chart.xAxis[0].setCategories(options.categories, false);

        chart.addSeries({
            type: options.type,

            data: options.data,

        chart.redraw();
    }
