echarts饼图中间插入文字、legend右边数字实现右对齐、legend左边插入自定义图片

实现效果如图：

饼图中间插入文字看series里面的label；插入图片和右对齐看legend：

let optionKindergarten = {
        tooltip: {//点击饼图显示的提示框
          extraCssText: "z-index:88",
          formatter: e => {//提示框文字格式
            return `${e.marker}${e.name.replace("数量", "")}<br>
                    人数：${e.data.value}<br>
                    占比：${e.data.peopleNum}`;
          }
        },
        title: {//标题
          text: this.chartTitle,//:幼儿园疫苗接种情况
          padding: [16, 0, 0, 0],
          textStyle: {
            fontSize: 14,
            color: "#687F96",
            fontWeight: 200
          }
        },
        legend: {//右边图例
          top: "32%",//距上
          right: "8%",//距右
          orient: "vertical",//纵向排列
          itemWidth: 13,//图片宽(针头)
          itemHeight: 13,//图片高
          itemGap: 10,//间隙
          data: [//给legend左边插入自定义图片,firstImg为变量要引入
            {
              name: "第一针",
              icon: "image://" + firstImg + ""
            },
            {
              name: "第二针",
              icon: "image://" + secondImg + ""
            },

            {
              name: "未接种",
              icon: "image://" + forthImg + ""
            },
          ],
          textStyle: {
            color: "#687F96",
            rich: {
              name: {//legend左边的文字:第一针、第二针...
                fontSize: 10,
                padding: [3, 10, 0, 0]//1.左边的文字添加右边距10(可自己调整)
              },

              }
