ecahrts饼图 指示线文字 自定义 （显示指示线和百分比）

1.指示线显示具体数值

formatter: "{c}"

代码：

 series: [
          {
    
    
            name: "",
            type: "pie",
            radius: "50%",
            center: ['50%', '46%'],
            data: this.chartData,
            emphasis: {
    
    
              itemStyle: {
    
    
                shadowBlur: 10,
                shadowOffsetX: 0,
                shadowColor: "rgba(0, 0, 0, 0.5)",
              },
            },
            label: {
    
    
              normal: {
    
    
                show: true,
                textStyle: {
    
    
                  fontSize: 22
                },
                formatter: "{c}"
              },
            },

          },
        ],

2.指示线显示百分比

formatter: "{d}"

   series: [
          {
    
    
            name: "",
            type: "pie",
            radius: "50%",
            center: ['50%', '46%'],
            data: this.chartData,
            emphasis: {
    
    
              itemStyle: {
    
    
                shadowBlur: 10,
                shadowOffsetX: 0,
                shadowColor: "rgba(0, 0, 0, 0.5)",
              },
            },
            label: {
    
    
              normal: {
    
    
                show: true,
                textStyle: {
    
    
                  fontSize: 22
                },
                formatter: "{d}"
              },
            },
          },
        ],    

2.指示线显示文字

formatter: "{b}" 也可以不设置 默认展示文字，和图例文字保持一致

 series: [
          {
    
    
            name: "",
            type: "pie",
            radius: "50%",
            center: ['50%', '46%'],
            data: this.chartData,
            emphasis: {
    
    
              itemStyle: {
    
    
                shadowBlur: 10,
                shadowOffsetX: 0,
                shadowColor: "rgba(0, 0, 0, 0.5)",
