javascript - Highcharts 中是否有子子下钻支持？

Question

我希望在我的图表中进行子子钻取，以下是相同的代码。

// Create the chart
Highcharts.chart('container', {
    chart: {
        type: 'column'
    },
    title: {
        text: 'Highcharts multi-series drilldown'
    },
    subtitle: {
        text: 'Click columns to drill down to single series. Click categories to drill down both.'
    },
    xAxis: {
        type: 'category'
    },

    plotOptions: {
        series: {
            borderWidth: 0,
            dataLabels: {
                enabled: true
            }
        }
    },
    series: [
      {
          name: '2010',
          data: [{
              name: 'Republican2',
              y: 5,
              drilldown: 'republican-2010'
          }]
      }
    ],
    drilldown: {
        series: [
          {
                name: 'Republican3',
              id: 'republican-2010',
              data: [{
                name: 'test',
                y: 3,
                drilldown: 'republican-2080'
              }]
          }
        ],
        drilldown: {
            series: [{
              id: 'republican-2080',
              data: [
                  ['East', 4],
                  ['West', 2],
                  ['North', 1],
                  ['South', 4]
              ]
                }]
        }
    },// End Main drill down

});

在第一次向下钻取之前它工作正常，并且我遵循主要向下钻取结构来获取子子向下钻取。不确定 High Chart 是否支持它，或者我做错了什么。

任何帮助都会被适当..
