qyhever opened a new issue #11052: echarts bmap绘制散点图，数据量过大时拖拽地图小点会重新渲染 URL: https://github.com/apache/incubator-echarts/issues/11052 ### Version 4.2.1 ### Reproduction link [https://qyhever.top/echarts-scatter](https://qyhever.top/echarts-scatter) ### Steps to reproduce 直接访问链接，拖拽操作地图 ### What is expected? 拖拽地图，小点不会重新渲染 ### What is actually happening? 拖拽地图，小点重新渲染（会闪烁） --- 通过 echarts 的 scatter 散点图结合 bamp 扩展插件，来标记客户在地图中的位置。经过测试，数据量在3000以下时，不会出现上述描述的情况；数据量超过3000后，每次拖拽地图都会重新渲染（即地图上的标记点会闪烁），视觉效果不太好。是否有内置的配置可以解决此问题？ <!-- This issue is generated by echarts-issue-helper.
