Wipe animation with GSAP or JavaScript

Hi All,

I am working on a project where I want to show the progression of a graph in the timeline. What I'm looking to do is to have a wipe animation from the left, triggered by a button click, which brings the graph image to a certain place in its timeline. A second button click will continue the wipe image to the next place, a third click will continue the wipe, and so on. In total there will be like 5 places where the wipe image should stop and then continue. 

...is this possible in Storyline?
