Hi Shuang, I think it a good idea to expose mouse events on *grid*. By mouse events, I mean something like mouseenter, mousemove, mouseleave and etc. Recently we got this issues asking exactly the same thing: https://github.com/apache/incubator-echarts/issues/9281 .
We should probably provide events on grid first, and later on, we can also provide events on other components.
