    public Result members() {
        List<User> list = userService.list();
        //四个季度
        int q1 = 0;

            }
        }
        return Result.success(CollUtil.newArrayList(q1, q2, q3, q4));
    }

Home.vue

<el-col :span="12">
        <div id="main" style="width: 500px;height: 400px"></div>
      </el-col>



var option = {
      title: {
        text: '各季度会员数量趋势图',
        subtext: '趋势图',
        left: 'center'
      },
      xAxis: {
        type: 'category',
        data: ["第一季度","第二季度","第三季度","第四季度"]

      },
      series: [
        {
          data: [],
          type: 'line'
        },

    };
    var chartDom = document.getElementById('main');
    var myChart = echarts.init(chartDom);

    this.request.get("/echarts/members").then(res =>{
      //填空

      option.series[1].data = res.data
      //数据准备完毕之后在set
      myChart.setOption(option);
    })

三、饼图

//饼图
    var pieOption = {
      title: {
        text: '各季度会员数量比例图',
        subtext: '比例图',
        left: 'center'
      },
      tooltip: {
        trigger: 'item'
      },
      legend: {
        orient: 'vertical',
        left: 'left'
      },
      series: [
        {
          type: 'pie',
          radius: '60%',
          //饼图上的文本标签
          label:{
            normal:{
              show:true,
              //标签的位置
              position:'inner',
              textStyle:{
                fontWeight:300,
                fontSize:14,
                color:'#fff'
              },
              formatter:'{d}%'
            }
          },
          data: [],//填空
          emphasis: {
            itemStyle: {
              shadowBlur: 10,
              shadowOffsetX: 0,
              shadowColor: 'rgba(0, 0, 0, 0.5)'
            }
          }
        }
      ]
    };



    var pieDom = document.getElementById('pie');
    var pieChart = echarts.init(pieDom);

    this.request.get("/echarts/members").then(res =>{

      pieOption.series[0].data = [
        {name:'第一季度',value:res.data[0]},
        {name:'第二季度',value:res.data[1]},
        {name:'第三季度',value:res.data[2]},
        {name:'第四季度',value:res.data[3]},
      ]
      pieChart.setOption(pieOption)
    })
  }
