vue中使用echarts-gl(3d环形图)
echarts-gl
Extension pack for Apache ECharts, providing globe visualization and 3D plots.
项目地址:https://gitcode.com/gh_mirrors/ec/echarts-gl
免费下载资源
·
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
然后就是导入
import echarts from 'echarts'
import 'echarts-gl'
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
