好，下面上货。

1、首先需要引入echart模块。

npm install echarts --save

2、然后在main.js中添加如下内容：

importechartsfrom'echarts'

Vue.prototype.$echarts=echarts;

3、在界面中使用echart。

<template>
      <div>
        this is chart example<br/>
        <div>{
        {selected}}</div>
    
        <div>
          <div id="myChart" :style="{width: '600px', height: '500px'}"></div>
        </div>
      </div>
    </template>
    
    <script>
      import {mapGetters, mapActions} from 'vuex'
      export default {
        data () {
          return {
            msg: 'Welcome to Your Vue.js App',
            myChart: {},
            selected: {
              "直接访问": true,
              "邮件营销": true,
              "联盟广告": true,
              "视频广告": true,
              "搜索引擎": true,
              "百度": true,
              "谷歌": true,
              "必应": true,
              "其他": true
            }
          }
        },
        mounted: function () {
          let that = this;
          let myChart = this.$echarts.init(document.getElementById('myChart'));
          that.myChart = myChart;
          that.drawLine();
          that.myChart.on('legendselectchanged', function (params) {
            // 获取点击图例的选中状态
            let isSelected = params.selected[params.name];
            that.selected = params.selected;
            // 在控制台中打印
            console.log((isSelected ? '选中了' : '取消选中了') + '图例' + params.name);
            // 打印所有图例的状态
            console.log(params.selected);
          });
        },
        methods: {
          drawLine: function () {
            let option = {
              tooltip: {
                trigger: 'axis',
                axisPointer: {            // 坐标轴指示器，坐标轴触发有效
                  type: 'shadow'        // 默认为直线，可选为：'line' | 'shadow'
                }
              },
              legend: {
                data: ['直接访问', '邮件营销', '联盟广告', '视频广告', '搜索引擎', '百度', '谷歌', '必应', '其他']
