Rychou opened a new issue #11404: 采样策略过滤了自己手动插入的null值数据的问题
URL: https://github.com/apache/incubator-echarts/issues/11404
 
 
   ### Version
   4.3.0
   
   ### Reproduction link
   [https://gallery.echartsjs.com/editor.html?c=xIRfTIQTs&v=1](https://gallery.echartsjs.com/editor.html?c=xIRfTIQTs&v=1)
   
   ### Steps to reproduce
   点开重现链接，可以看见图表中间有一条连线，并且关闭了connectNulls选项
   
   ### What is expected?
   为了实现“时间跨度较大的数据不连线的效果”，手动在数据中插入了两个null值数据，并将connectNulls设为false。这样能实现。
   
   ### What is actually happening?
   开启了采样策略之后，null值数据可能被过滤了，导致结果不符合预期。将图表放大一定程度后，发现又符合预期效果。所以估计是采样策略过滤了null值的原因。
