echarts圆形统计图例子

1、先展示效果图

2、直接上代码，把我代码copy拿去调一下就知道了（引用echarts插件看之前的文章）

<template>
  <div class="employee-container">
    <div class="top-content">
      <span class="top-title">员工账号数统计</span>
    </div>
    <div id="statistical-chart"></div>
  </div>
</template>

<script>
  import {
    mapState
  } from 'vuex'
  export default {
    name: "EmployeeDataStatistics",
    data() {
      return {
        chartBox: null
      };
    },
    computed: {
      ...mapState(["employeeDataStatus"]) // 接口返回的数据存储在这里
    },
    created() {},
    mounted() {
      this.echart()
    },

    methods: {

      // 2. echart图表
      echart() {
        if (this.chartBox != null && this.chartBox != "" && this.chartBox != undefined) {
          this.chartBox.dispose() //销毁
        }
        this.chartBox = this.$echarts.init(document.getElementById("statistical-chart"));
        const option = {
          tooltip: {
            trigger: 'item'
          },
          color: ['#3eae5f', '#fcca00', '#5e5e5e'],
          series: [{
            name: '员工账号数据统计',
            type: 'pie',
            radius: '50%',
            data: [{
                value: this.employeeDataStatus[1].quantity,
                name: this.employeeDataStatus[1].statusDescription + '账号数' + this.employeeDataStatus[1]
                  .quantity + '个'
              },
              {
                value: this.employeeDataStatus[2].quantity,
                name: this.employeeDataStatus[2].statusDescription + '账号数' + this.employeeDataStatus[2]
                  .quantity + '个'
              },
              {
                value: this.employeeDataStatus[3].quantity,
                name: this.employeeDataStatus[3].statusDescription + '账号数' + this.employeeDataStatus[3]
                  .quantity + '个'
              }
            ],
            emphasis: {
              itemStyle: {
                shadowBlur: 10,
                shadowOffsetX: 0,
                shadowColor: 'rgba(0, 0, 0, 0.5)'
              }
            }
          }]
        };
        this.chartBox.setOption(option);
        // 根据页面大小自动响应图表大小
        // window.addEventListener("resize", function () {
        //   this.chartBox.resize();
        // });
      },
    },
  };
</script>
