在我的系列中我已经有一个json数据用于名称，y和下钻的值。在'Animals':{ name: 'Animals', data: ['Cows',2], ['Sheep', 3]]}内的钻取数据方面真的很难。我需要这些动态数据请帮忙

这部分：

                if (!e.seriesOptions) {
                    var chart = this,
                        drilldowns = {
                            'Animals': {
                                name: 'Animals',
                                data: [
                                    ['Cows', 2],
                                    ['Sheep', 3]
                                ]
                            },
                            'Fruits': {
                                name: 'Fruits',
                                data: [
                                    ['Apples', 5],
                                    ['Oranges', 7],
                                    ['Bananas', 2]
                                ]
                            },
                            'Cars': {
                                name: 'Cars',
                                data: [
                                    ['Toyota', 1],
                                    ['Volkswagen', 2],
                                    ['Opel', 5]
                                ]
                            }
                        },
                        series = drilldowns[e.point.name];

                    // Show the loading label
                    chart.showLoading('Simulating Ajax ...');

                    setTimeout(function () {
                        chart.hideLoading();
                        chart.addSeriesAsDrilldown(e.point, series);
                    }, 1000);
                }

只是动态添加下钻的简单示例。您可以使用AJAX调用作为注释中的建议：

                if (!e.seriesOptions) {
                    var chart = this,
                        series = drilldowns[e.point.name];

                    // Show the loading label
                    chart.showLoading('Loading...');

                    $.get('/my/url', e.point.name, function(data) {
                        chart.hideLoading();
                        chart.addSeriesAsDrilldown(e.point, data);
                        // where data is for example: 
                        // { name: 'Cars', data: [ ['Toyota', 1], ['Volkswagen', 2], ['Opel', 5] ] }
                    });
                }

希望这有助于其他任何人。你可以，如果你想这样做，虽然这不能解决你的问题，但是这个方法有效，将数据/ json分开并使用ajax调用数据。

  var chartSeriesData = [];

  var chartDrilldownData = [];

$.ajax({
type: 'GET',
url: 'db/jsondata.json',
success: function(data) {


    var agentJson = data;

    for (var i = 0;i <agentJson.agentinfo.length; i++)

        {

        var series_name = agentJson.agentinfo[i].name;
        var drill_id = agentJson.agentinfo[i].drilldown;
        var series_data = agentJson.agentinfo[i].y;

        var drill_data = agentJson.agentinfo[i].data;


              chartSeriesData.push({
                 name: series_name,
                 y: parseFloat(series_data),
                 drilldown : drill_id                                     
              }); 


         chartDrilldownData.push({
             data : drill_data,
             id: drill_id,
             name: series_name,

         });


        }

    /// END FOR LOOP


    $('#agentInfo').highcharts({

        credits: {
            enabled: false
        },
        colors: ['#4B2572', '#8E227D', '#7904e0', '#b726b5', '#64E572', '#ed9cdf', '#f704ce', '#780a84', '#8e4696', '#cd92d3', '#551c5b'],

使用json的Highcharts Dynamic Drilldown
