javascript - Highcharts 从 bar-->pie 或 bar-->column 向下钻取

Question

我需要创建一个带有向下钻取饼图的条形图。在所有浏览器中一切正常，但

您需要更多解释吗？

    function activities(params) {

    //params coming from statistics controller

            categories = activities_category_names,

            data = activities_category_data

        function setChart(chart, options) {
            chart.series[0].remove(false);
            chart.xAxis[0].setCategories(options.categories, false);

问题是高图表中的错误。我在 3.0.1 上运行导致错误，他们在 2 天前切换到 3.0.2 并且问题已解决。

对于任何对从条形图到饼图的向下钻取图感兴趣的人...在这里您可以找到示例。

这是代码：

HTML：

<script src="http://code.highcharts.com/3.0.2/highcharts.js"></script>
<div id="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]]}}],

var colors = Highcharts.getOptions().colors,
