I got the same shapes when I use offset function in Timelion.  
Is that my mistake or something wrong with offset function of Timelion?

I think there is some confusion about the `offset` parameter. This parameter shifts the time of the input series by the specified amount (in this case 2 days). So the shape will always be exactly the same, just shifted on the x-axis.

What were you trying to achieve? Maybe there is another function or parameter for that.

Thank you for your reply.  
I suppose that the offset function will remove the data corresponding with the provided time range and re-calculate the metric, so the shape should change.  
In my case, I use count metric so it might not affect the shape but when I use metric=avg it will difference, right?
