support for openlayers5+ |
ol 7.x 以后请使用 ol-echarts v4.x，ol 7.x 之前请使用 ol-echarts v3.x，原因见 issues/115
git clone https://github.com/sakitam-fdd/ol3Echarts.git
yarn run bootstrap
yarn run dev
yarn run build
yarn run karma.test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 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。

var Map = new ol.Map({

new ol.layer.Tile({

})
],
loadTilesWhileAnimating: true,
view: new ol.View({

var echartslayer = new ol3Echarts(echartsOption, {

echartslayer.appendTo(Map)
</script>如果你已经对 ol 执行构建 build-legacy 那么你将能够获取一个可以通过 script 引入的 ol.js 包，这样的话你也可以使用
ol-echarts 下的 ol-echarts.js, 如果碰到鼠标事件问题，请参照 issues #45
