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';
vue中reactive
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.hart);
// 指定图表的配置项和数据
var option = {
tooltip: {
trigger: "axis",
axisPointer: {

parms[0].marker +
"今天登录：" +
parms[0].value + '次'
return str;

// 使⽤刚指定的配置项和数据显⽰图表。

}
//挂载
