TweenMax: from flat line to multiple points

Hello everyone - I have a chart class and I have an array of Points for a line that falls on the graph.

I think it would be cool if the line started out as flat (i.e., y=_height/2 for all points) and then the y points of the line animate into place.

I don’t even know where to start with doing this in TweenMax/Lite… I’ve seen several code snippets that draw a line from left to right, but that’s not what I want.

Any ideas?
