Why can't I horizontally scale a shape in my sequence?

[Mwarren]

There is an extremely basic thing I need to accomplish: Take a shape and scale it horizontally over-time (to align with a given section), such as in the following example:

Now, I have done this at least five times. But for some reason, I'm flatly unable to accomplish this. So I have either popped a rivet (not impossible) or something subtle has changed. Normally, I would draw out my shape, then set my keyframes and then drag out the two rightmost shape handles to 'fill' the whole line.

But now I find that I can't select individual points on the shape. And I can't scale it horizontally. I have no idea how to do this very basic thing and would love some guidance. This is driving me absolutely insane and costing me too much time.

Half-figured something out. If the shape is too small, then I lose the ability to resize it with the handles.

What if you use the Zoom Level in the Program Monitor or unlocked scale in the EGP?

[Mwarren]

I cannot understand either of those recommendations. Can you elaborate?

[Mwarren]

I am trying everything but no luck. I have created keyframes on the Vector Motion option for the graphic. I have tried to Keyframe the Transform/Position & Scale values but its as though keyframes don't exist. I only modify the graphic as a whole. Timeline is irrelevant.

AHA: Horizontal and Vertical Scale are unlocked after I select Uniform Scale, which only appears under the Shape Option. 

[Mwarren]

Buuuut, then you are limited by how wide it can be. Not even close enough.

This is SO INFURIATING.

[Mwarren]

Okay, for real, it's PATH. Keyframing that works. Thank god.

I just tried animating the position property and it works fine. I created 3 shapes inside an Essential Graphics template.

BTW: AE is way easier/better for this stuff.
