Vue3使用Echarts图表
<template>
<h1>Echarts图表</h1>
<div id="myChart" style="width:1500px;height:500px;margin:auto;"></div>
</template>
<script>
// 引入echarts
import * as echarts from 'echarts'

export default {
setup() {
onMounted(() => { // 需要在页面加载完毕后展示图表，这里使用Vue3的组合式生命周期钩子 onMounted()
let myChart = echarts.init(document.getElementById("myChart"));
// 设置图表配置项,可以直接从Echarts的示例中，将配置项复制下来后放入下列的()中实现图表的样式更换
