> A `coordinateSystem` in your case is required. If you want to use echarts in leaflet, you may need an echarts plugin for leaflet. Within the example, it can draw polygons by using the [custom series](https://echarts.apache.org/en/option.html#series-custom) since it depends on the plugin [Extension for Baidu Map](https://github.com/apache/incubator-echarts/tree/master/extension/bmap) which is provided officially. > There may be no need to use bmap, you can search in Github with the keyword `leaflet-echarts` to pick one suitable for you. > BTW, I think the version you are using is too old, it's better to upgrade it to 4.x. :) > >  yess. I use echarts-leaflet, the third one in the pic I updated the echarts to 4.X.X but still got "prepareCustoms[coordSys.type] is not a function" ---------------------------------------------------------------- This is an automated message from the Apache Git Service.
