vue 数据可视化大屏 项目开发中，需要使用echarts饼状图效果。

饼状图legend在左下角

饼状图label分为两行，上面标题，下面百分比

饼状图根据数据显示不同的大小

饼状图中心显示数字以及总标题

演示实例

使用组件

<template>
  <div class="itemBodys">
    <echarts :list="list"></echarts>
  </div>
</template>

<script>
import echarts from "./components/echarts.vue";
export default {
  data() {
    return {
      list: [{
        name: '未执行',
        value: 10
      }, {
        name: '执行中',
        value: 20
      }, {
        name: '未完成',
        value: 30
      }, {
        name: '按路线完成',
        value: 30
      }, {
        name: '未按路线完成',
        value: 30
      }]
    }
  },
  components: {echarts}
}
</script>

<style lang="scss" scoped>
.itemBodys {
  width: 100%;
  position: relative;
  height: calc(100% - 0px);
}

.echartsBody {
  position: relative;
  width: 100%;
  height: calc(100% - 0px);
  display: flex;
  justify-content: flex-start;
  align-items: center;
  flex-wrap: nowrap;
  flex-direction: row;
  align-content: flex-start;
}
</style>

echarts 组件
