ol3-echarts / ol-echarts

ol3-echarts：基于openlayers(3/4)新版扩展的echarts图表插件，暂时支持echarts的所有map组件类型，对普通不支持坐标系的图表正在兼容（饼图，柱状图，折线图已兼容）
ol-echarts：基于 openlayers5(ol package)扩展的数据可视化插件，功能和 ol3-echarts 保持一致。

下载

git clone https://github.com/sakitam-fdd/ol3Echarts.git
yarn run bootstrap
yarn run dev
yarn run build
yarn run karma.test
yarn run karma.cover

安装

npm安装

注意：npm下存在两个包 ol3-echarts 和 ol-echarts 前者是在使用 openlayers 或者是 ol 的cdn时使用；后者是在使用 ol 配合打包工具使用。

// old openlayers package
npm install ol3-echarts --save
import ol3Echarts from 'ol3-echarts'

// ol package
npm install ol-echarts --save
import EChartsLayer from 'ol-echarts'

cdn

cdn 引用方式只支持旧版 openlayers 和新版 ol 的cdn引用方式，统一使用 ol3-echarts 支持。

目前可通过 unpkg.com / jsdelivr 获取最新版本的资源。

// jsdelivr (jsdelivr由于缓存原因最好锁定版本号)
