前言：

vue3.0實現echarts立體柱圖

實現效果：

實現步驟：

1、安裝echarts

cnpm i --save echarts

2、頁面定義容器

<template>
  <div ref="echart" class="echartDiv"></div>
</template>

3、js中引入echarts

import * as echarts from 'echarts';

組件完整源碼：

<template>
  <div ref="echart" class="echartDiv"></div>
</template>
 
<script>
import * as echarts from 'echarts';
import { onMounted,toRefs, ref,reactive } from 'vue';

      yAxisData1:[1,1,1,1,1,1],
      echart: ref(),
    })
    const echartInit = () =>{
      var myChart = echarts.init(state.echart);
