   为了方便我们能够复现和修复 bug,请遵从下面的规范描述您的问题。

   ### One-line summary [问题简述]
   line线图初始化或者数据更新的时候的动画效果,都是沿着x轴从左往右发生的缓动效果。如这个例子:
   http://www.echartsjs.com/gallery/editor.html?c=line-easing 。 这样子,数据发生更新的时候带来的动画效果很突兀。
   
   我希望,线图初始化或者数据更新的时候,是沿着y轴发生缓动效果的。如这个例子:https://www.dbface.com/assets/echarts/doc/example/line3.html
   
   ### Version & Environment [版本及环境]
   + ECharts version [ECharts 版本]: 4.2.0-rc.1
   + Browser version [浏览器类型和版本]:
   + OS Version [操作系统类型和版本]:
   
   
   ### Expected behaviour [期望结果]
   
   line chart的初始和数据更新动画效果如这个demo所示:
