vue中使用echarts-gl（3d环形图）_vue echarts-gl

以这个为例子：https://www.makeapie.com/editor.html?c=x1-kIyaV6u
记得要先下载echarts 和echarts-gl

npm install echarts
npm install echarts-gl
1
2

然后就是导入

	import echarts from 'echarts'
	import 'echarts-gl'
1
2

补充一点将这个映入到自己的项目中去的时候可能会出现背景色
需要修改environment: "auto", 自动适应。
然后就是效果图

最后就是代码

<template>
