echarts饼图同时设置两个label标签产生的问题？

Question

echarts饼图同时设置两个label标签,内(显示百分比)外(显示数据和文字描述)后,判断当一个数据为零时(目前只有两个数据),另一个数据百分比无法在整个饼图中垂直水平居中，怎么解决？
代码如下：
难道是我这个需求过分了吗

 initPieChart(totalBalance, privateTotalBalance) {
      privateTotalBalance = 2000000000;
      totalBalance = 0;
      if (!!this.$refs.piecharts) {
        var myChart = echarts.init(this.$refs.piecharts);
        myChart.setOption({
          color: ["#228BFF", "#FFB218"],
          padding: [-80, 0],
