[GitHub] [echarts] srinathmerugu opened a new issue #16466: [Feature] How to plot points on map and need an background map for echarts
srinathmerugu opened a new issue #16466:
URL: https://github.com/apache/echarts/issues/16466
### What problem does this feature solve?
1. I want to plot points by fetching data from the geoserver response, I was not able to find an example to plot points in echarts geo/map examples, so is there a way to plot point type using echarts?
2. I need a background map along with the map i'm plotting
I tried using echarts-leaflet.js for the background map, but my echarts USA States map is not exactly rendering on the USA map of leaflet, please find it in the attachment below
### What does the proposed API look like?
Plot points as markers and render echarts map above the background map

Currently we haven't support draw `map` series on a map services like leaflet. Perhaps you can have a try on the `projection` option provided since 5.3

Hi, I'm currently plotting points using scatter type with my custom symbol using echarts-leaflet
But whenever i zoom in, zoom out and drag on map, i can see there's a delay on map for plotting points. Points are being spread and then sits back on the coordinates which doesn't give a good user experience.
I'm sharing the screenshots below of points getting delayed
- zoom in
- zoom out
- drag
