KyleBing opened a new issue #11034: 一个表中，多个曲线，换 option 的时候，残留多余的曲线
URL: https://github.com/apache/incubator-echarts/issues/11034
 
 
   ### Version
   4.2.1
   
   ### Steps to reproduce
   有个页面中，我设置了两个 option 对象, `optionK` `optionLine`，两个是完完全全不同的。
   在k线图的 `option` `series` 添加了几个MA曲线，但在 `optionLine` 没有。
   
   在从 optionK 切换到 opitonLine 的时候，会残留 所有的ma曲线，如下图：

   在没有定义曲线的页面中出现多余曲线
   
   ### What is actually happening?
