海图森伯斯特不能有一个传说吗？

Question

我在与angularjs一起使用图表。还尝试使用不是典型图表的森伯斯特。是否有可能在海图上有一个朝阳的传说？ The example from their websites没有显示任何图例。 Here is an example是我到目前为止所做的。这是配置

   var sunburstObj = {
        credits: {
          enabled: false
        },

        colors: [
          "rgba(0,0,0,0)",
          "rgba(219,199,157,1)",
          "rgba(70,45,0,1)",
          "rgba(250,246,237,1)",
          "rgba(166,84,27,1)",
          "rgba(92,102,112,1)"
        ],

        tooltip: {
          headerFormat: "",
          pointFormat: "{point.name}-{point.value}"
        },

        legend: {
          enabled:true,
          labelFormatter: function() {
            return this.name;
          },
          width: "100%"
        },
        plotOptions: {
          sunburst: {
            allowDrillToNode: false,

            allowPointSelect: true,
            borderWidth: 0,
            cursor: "pointer",
            dataLabels: {
              format: "{point.name}",
              filter: {
                property: "innerArcLength",
                operator: ">",
                value: 16
              }
            },
            levels: [
              {
                level: 1,
                levelIsConstant: false,
                dataLabels: {
                  enabled: false
                }
              },
              {
                level: 2,
                colorByPoint: true
              }
            ]
          }
        },
        series: [
          {
            type: "sunburst",
            data: assetData,
            name: "test",
            showInLegend:true
          }
        ]
      };
