Echarts之内嵌圆环图v5.1.2

相比v4，v5有些许变动。我也没看官方文档，就对着浏览器开发者工具报错的地方一个一个调的，又综合了别人的经验，代码如下

放在drawPieAll function下

 drawPieAll() {
      // myChart paint more times, it will warn
      if (
        this.myChart != null &&
        this.myChart != "" &&
        this.myChart != undefined
      ) {
        this.myChart.dispose();
      }
      this.$nextTick(() => {
        this.myChart = echarts.init(document.getElementById("pieAll"));
