echarts與echarts-gl 實(shí)現(xiàn)3D餅圖

實(shí)現(xiàn)效果：

旋轉(zhuǎn)效果

縮放效果

實(shí)現(xiàn)步驟

1、安裝echarts
npm install echarts
npm install echarts-gl
2、頁(yè)面定義容器

<template>
  <div class="echarts">
    <!-- <div :id="echarts_id" style="width: 400px;height: 400px;"></div> -->
    <div id="echarts_id" style="width: 100%;height: 100%;"></div>
  </div>
</template>

3、js中引入echarts文章來(lái)源地址http://www.zghlxwxcb.cn/news/detail-858441.html

import * as echarts from 'echarts'
import 'echarts-gl'

VUE 組件完整源碼：
