sjtuzwj opened a new issue #10443: 数据框选无法正确选中密集数据
URL: https://github.com/apache/incubator-echarts/issues/10443
 
 
   ### Version
   4.2.1
   
   ### Steps to reproduce
   
   我使用4000个数据样本，在8*10的方格上绘制散点图，要求能根据框选导出被选点的索引，但是某些区域无法导出索引，但是，在dataZoom放大后，导出又正确。
   
   ### What is expected?
   
   导出正确数目的数组样本（如140）
   
   ### What is actually happening?
   
   在正常视图下无法正确选中，放大后才能正确运行。

   我怀疑可能和brush点与图大小相比过于密集有关，可能是某些地方出现了崩溃才返回了空值。
