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: {

          },
          grid: {
            left: '3%',
            right: '4%',
            bottom: '3%',
            containLabel: true
