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",
          axisPointer: {
            type: "shadow", // 默认为直线，可选为：'line' | 'shadow'
          },
          formatter: function(parms) {
            var str =
              parms[0].axisValue +
              "</br>" +
              parms[0].marker +
              "今天登录：" +
              parms[0].value + '次'
            return str;
          },

        },

          },
          axisLabel: {
            margin: 20, //刻度标签与轴线之间的距离。
            textStyle: {
              color: "#000",
            },
          },
