（实战项目篇）vue3.0系列（vue2.）使用echart
```bash
<template>
<div class>
<div id="myChart" :style="{ height: '500px',}"></div>
</div>
</template>
<script>
// 引入基本模板
let echarts = require('echarts/lib/echarts')
// 引入柱状图组件
require('echarts/lib/chart/bar')
// 引入提示框和title组件
require('echarts/lib/component/tooltip')
require('echarts/lib/component/title')
export default {
name: 'hello',
data() {
return {
msg: 'Welcome to Your App'
}
},
mounted() {
this.drawLine();
},
methods: {
drawLine() {
// 基于准备好的dom，初始化echarts实例
let myChart = echarts.init(document.getElementById('myChart'))
// 绘制图表
myChart.setOption({
title: { text: 'ECharts' },
tooltip: {},
xAxis: {
data: ["衬衫", "羊毛衫", "雪纺衫", "裤子", "高跟鞋", "袜子"]
},
yAxis: {},
series: [{
