在Vue中使用echarts

一，安装echarts

cnpm i echarts -S

二，新建echarts.vue

内容如下：

<template>
    <div class="chart-container">
        <el-row>
            <el-col :span="12">
                <div id="chartColumn" style="width:500px; height:400px;"></div>
            </el-col>
            <el-col :span="12">
                <div id="chartBar" style="width:500px; height:400px;"></div>
            </el-col>
            <el-col :span="12">
                <div id="chartLine" style="width:500px; height:400px;"></div>
            </el-col>
            <el-col :span="12">
                <div id="chartPie" style="width:500px; height:400px;"></div>
            </el-col>
        </el-row>
    </div>
</template>

<script>
