Question

Highcharts，您可以更改向下钻取的图表类型吗？

我想首先展示一个标准的“柱状”图表，然后深入到“条形”图表，我已经尝试了所有我能想到的......

我假设它会在钻取代码中设置，但似乎不是这样工作的。
就像在...

drilldown: {
    type: 'pie',
    name: 'Chart1',
    categories ['1','2','3','4','5','6','7','8','9','10','11','12','13','14','15','16','17','18','19','20','21','22','23','24','25','26','27','28'],
    data: [1,2,3,4,5,6,7,8,9,10,1,2,3,4,5,6,7,8,9,10,1,2,3,4,5,6,7,8],
    color: colors[0]
}

Answer 1

我不知道你试过什么，但你可以做到。
看看我的 example 。

$(function () {
    var chart;
    $(document).ready(function() {

        var colors = Highcharts.getOptions().colors,
            categories = ['MSIE', 'Firefox', 'Chrome', 'Safari', 'Opera'],
            name = 'Browser brands',
            data = [{
                    y: 55.11,
                    color: colors[0],
                    drilldown: {
                        name: 'MSIE versions',
                        categories: ['MSIE 6.0', 'MSIE 7.0', 'MSIE 8.0', 'MSIE 9.0'],
                        data: [10.85, 7.35, 33.06, 2.81],
                        color: colors[0]
                    }
                }, {
                    y: 21.63,
                    color: colors[1],
                    drilldown: {
                        name: 'Firefox versions',
                        categories: ['Firefox 2.0', 'Firefox 3.0', 'Firefox 3.5', 'Firefox 3.6', 'Firefox 4.0'],
                        data: [0.20, 0.83, 1.58, 13.12, 5.43],
                        color: colors[1]
                    }
                }, {
                    y: 11.94,
                    color: colors[2],
                    drilldown: {
                        name: 'Chrome versions',
                        categories: ['Chrome 5.0', 'Chrome 6.0', 'Chrome 7.0', 'Chrome 8.0', 'Chrome 9.0',
                            'Chrome 10.0', 'Chrome 11.0', 'Chrome 12.0'],
                        data: [0.12, 0.19, 0.12, 0.36, 0.32, 9.91, 0.50, 0.22],
                        color: colors[2]
                    }
                }, {
                    y: 7.15,
                    color: colors[3],
                    drilldown: {
                        name: 'Safari versions',
                        categories: ['Safari 5.0', 'Safari 4.0', 'Safari Win 5.0', 'Safari 4.1', 'Safari/Maxthon',
                            'Safari 3.1', 'Safari 4.1'],
                        data: [4.55, 1.42, 0.23, 0.21, 0.20, 0.19, 0.14],
                        color: colors[3]
                    }
                }, {
                    y: 2.14,
                    color: colors[4],
                    drilldown: {
                        name: 'Opera versions',
                        categories: ['Opera 9.x', 'Opera 10.x', 'Opera 11.x'],
                        data: [ 0.12, 0.37, 1.65],
                        color: colors[4]
                    }
                }];

        function setChart(options) {
            chart.series[0].remove(false);
            chart.addSeries({
                type: options.type,
                name: options.name,
                data: options.data,
                color: options.color || 'white'
            }, false);
            chart.xAxis[0].setCategories(options.categories, false);
            chart.redraw();
        }

        chart = new Highcharts.Chart({
            chart: {
                renderTo: 'container'
            },
            title: {

});

确保您没有为所有系列定义 type。 Reference
