fangfcg opened a new issue #10681: 如何通过设置zlevel实现局部更新?
URL: https://github.com/apache/incubator-echarts/issues/10681
 
 
   ### Version
   4.2.1
   
   ### Steps to reproduce
   no need to reproduce
   
   ### What is expected?
   如何解决通过setOption进行部分series重新绘制而不重新绘制所有的series的问题?
   
   ### What is actually happening?
   我设置了3个series,包括一个数据量很大的heatmap和两个数据量很小的scatter,现在我只想更新scatter的数据(通过setInterval函数一秒更新一次),但是我发现当我调用setOption时,我的heatmap也被更新了,我阅读了 https://github.com/apache/incubator-echarts/issues/6618 的内容,这个问题和我一样,但是这个issue中看起来并没有解决这个问题。同样的,在 https://github.com/apache/incubator-echarts/issues/8834 中,问题看起来也没有被解决。
   
   我尝试使用了z-level属性,最后heatmap仍然被刷新了,目前并没有找到到底如何实现的办法,请问到底如何才可以实现对三条series中的两条series的更新而不更新另外一条?
