比较两个具有相同数据名称的饼图（Highcharts）-Java 学习之路

我对高级图表很新，我被卡住了 . 我有两个具有相同数据名但不同值的饼图 . 我想要实现的是在单击饼图时从两个饼图获取值，并在单击时旋转饼图 . 这是我的JSFiddle，我想要实现的是在下面的图像URL中 .

代码就在这里

您应该能够使用两个系列并使用point.events.click函数更新两个饼图：

point: {
    events: {
      click: function() {
        var chart = this.series.chart,
          series = chart.series,
          index = this.index,
          name = this.name;
        if (lastIndex >= 0) {
          Highcharts.each(series, function(s) {
            s.data[lastIndex].update({
              dataLabels: {
                enabled: false
              }
            });
          })
        }
        Highcharts.each(series, function(s, i) {
          s.data[index].update({
            dataLabels: {
              enabled: true
            }
          });

          moveToPoint(s.data[index], i);
        });
        lastIndex = index;
        $('.customLabel').remove();
        chart.renderer.label(name, chart.chartWidth / 2 + 50, 100).attr({
          align: 'center',
          'font-size': 24
        }).addClass('customLabel').add();
      }
    }
  }

您还应该能够使用firePointEvent函数以编程方式在图表加载上触发click事件：

var initChart = new Highcharts.Chart(options, function(chart) {
  chart.series[0].data[0].firePointEvent('click');
});
