1. 装置echarts依赖 npm install echarts --save
  2. 在main.js中全局中援用
import echarts from 'echarts'Vue.prototype.$echarts = echarts
<div id="main" style="width:100%;height:376px"></div>
 mounted(){    this.getEchartData()      },   methods: {    getEchartData() {          var chartDom = document.getElementById('main');          var myChart = echarts.init(chartDom);          var option;                    option = {              title: {                  text: '某站点用户拜访起源',                  subtext: '纯属虚构',                  left: 'center'              },              tooltip: {                  trigger: 'item'              },              legend: {                  orient: 'vertical',                  left: 'left',              },              series: [                  {                      name: '拜访起源',                      type: 'pie',                      radius: '50%',                      data: [                          {value: 1048, name: '搜索引擎'},                          {value: 735, name: '间接拜访'},                          {value: 580, name: '邮件营销'},                          {value: 484, name: '联盟广告'},                          {value: 300, name: '视频广告'}                      ],                      emphasis: {                          itemStyle: {                              shadowBlur: 10,                              shadowOffsetX: 0,                              shadowColor: 'rgba(0, 0, 0, 0.5)'                          }                      }                  }              ]          };                    option && myChart.setOption(option);      }  },
