option1 = title text 车辆所有权构成辆 left center tooltip trigger item legend left right top center orient vertic

要将图例显示在右侧，只需要将legend的left属性改为"left"即可。修改后的代码如下：

option1 = { title: { text: "车辆所有权构成（辆）", left: "center", }, tooltip: { trigger: "item", }, legend: { left: "left", // 修改为"left" top: "center", orient: "vertical", formatter: function (name) { var value; pic1data.forEach((item) => { if (item.name === name) { value = item.value; } }); return ${name}|${value}%; //返回出图例所显示的内容是名称+百分比 }, }, series: [ { name: "Access From", type: "pie", radius: ["40%", "70%"], avoidLabelOverlap: false, label: { show: false, position: "center", }, emphasis: { label: { show: false, fontSize: "40", fontWeight: "bold", }, }, labelLine: { show: false, }, data: [ { value: 32.6, name: "外租车辆" }, { value: 67.4, name: "自有企业" }, ], },

      // 就是这里！
      {
        name: "",
        z: -1,
        type: "gauge",
        radius: "-50%",
        center: [`50%`, `50%`],
        // 配置中间的数字
        detail: {
          // 调节数字位置
          offsetCenter: [0, 20],
          fontSize: 20,
        },
        pointer: {
          show: false,
        },
        axisTick: {
          show: false,
        },
        axisLine: {
          show: false,
        },
        splitLine: {
          show: false,
        },
        axisLabel: {
          show: false,
        },
        // 中间的字和数字 数据
        data: [
          {
            value: 180135,
            name: "总计",
          },
        ],
      },
    ],
  };
