thbgh opened a new issue #8532: 折线图堆叠  Bug
URL: https://github.com/apache/incubator-echarts/issues/8532
 
 
   ### One-line summary [问题简述]
   
   1.两个项目的数据相同时，折现居然是上下两条？？？
   2.两个项目，其中一个项目数据较大（我测试时是几K），另一个项目数据接近于0时，两个项目的折线图居然重合？？？
   
   
   
   ### Version & Environment [版本及环境]
   
   echarts版本 4.x.
   chrome浏览器最新版
   win7
   
   
   
   ### Expected behaviour [期望结果]
   1. 数据相同时，折线图应该重合。
   2.其中一个项目数据接近于0时，折线图应该贴近X轴。
