在项目vue中使用echarts的操作步骤

<template>
 <div id = "testChart"></div>
</template>

<script>
import {echartInit} from "../../../utils/echartUtils"
</script>

 export default {
  name: 'Test',  //vue该组件名称Test.vue
  mounted() {
   this.testChart = echartInit('testChart');  //初始化该echarts表
   /*this.testChart.setOption(this.option); */  // 如果是写死的数据，可以在这儿setOption()看效果
  },
}

   return {
