项目背景

实训步骤

安装Echarts

在项目本身目录下执行 

npm install echarts@4

在intro.vue文件中分别编写如下部分代码：

html代码

<template>
	<div id="app">
		<el-row :gutter="12">
			<el-col :span="8">
				<el-card class="box-card" style="height: 300px">
					<div slot="header" class="clearfix">
						<span class="charts_title">Echarts柱形图</span>
						<el-button style="float: right; padding: 3px 0" type="text">操作按钮</el-button>
					</div>
					<div id="chartColumn" style="width: 100%; height: 260px;">
					</div>
				</el-card>
			</el-col>
			<el-col :span="8">
				<el-card class="box-card" style="height: 300px">
					<div slot="header" class="clearfix">

	</div>
</template>

js代码

<script>
