vue3.0+echarts实现立体柱图

前言：

vue3.0实现echarts立体柱图

实现效果：

实现步骤：

1、安装echarts

cnpm i --save echarts

2、页面定义容器

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

3、js中引入echarts

import * as echarts from 'echarts';

组件完整源码：

<template>
  <div ref="echart" class="echartDiv"></div>
</template>
 
<script>
import * as echarts from 'echarts';
import { onMounted,toRefs, ref,reactive } from 'vue';
export default {
  setup(){
    let state = reactive({
      xAxisData:['浩星','妍仔','哆啦a梦','李强','王颖','老王'],
      yAxisData:[4,22,1,11,23,11],
      yAxisData1:[1,1,1,1,1,1],
      echart: ref(),
    })
    const echartInit = () =>{
      var myChart = echarts.init(state.echart);
      // 指定图表的配置项和数据
      var option = {
        tooltip: {
          trigger: "axis",
