### 一，安装echarts ###

cnpm i echarts@4.9.0 -S

### ![watermark_type_ZmFuZ3poZW5naGVpdGk_shadow_10_text_aHR0cHM6Ly9ibG9nLmNzZG4ubmV0L3FxXzQwMzIzMjU2_size_16_color_FFFFFF_t_70][] ###

（echarts通常用这种方式引入：import echarts from 'echarts'。如果不行的话，就用这种引入方式：import \* as echarts from 'echarts'。）

### 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>
        import echarts from 'echarts'

                    chartColumn: null,
                    chartBar: null,
                    chartLine: null,
                    chartPie: null
                }
            },
    
            methods: {
                drawColumnChart() {
                    this.chartColumn = echarts.init(document.getElementById('chartColumn'));
                    this.chartColumn.setOption({
