<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: '某站点用户访问来源',
                  subtext: '纯属虚构',
                  left: 'center'
              },
              tooltip: {
                  trigger: 'item'
              },
              legend: {
                  orient: 'vertical',
                  left: 'left',
              },
              series: [
                  {
                      name: '访问来源',
                      type: 'pie',
                      radius: '50%',
                      data: [

                          {value: 735, name: '直接访问'},

                      ],
                      emphasis: {
                          itemStyle: {
                              shadowBlur: 10,
                              shadowOffsetX: 0,
                              shadowColor: 'rgba(0, 0, 0, 0.5)'
                          }
                      }
                  }
              ]
          };
          
          option && myChart.setOption(option);
