Magic move only for constrained proportions?

Question

Dear all,
basically going nuts trying the same thing a lot of people did: animating charts. After finding out, that this is not possible in an easy way, I went even back to build the chart myself. In my case a line plot with two lines. I try to animate a change from one data-pattern to another (just 4 data points, hm?).
After reading Apples description on magic move I thought that should work: just add two line shapes, duplicate chart, move the lines on the second chart, magic move, ready. Or? Doesn't work. By fiddling around a bit, I probably nailed it down: Because lines don't have a size (only start and end point), changing any endpoint position breaks the magic move. But even further: For all other shapes, magic move breaks as soon as you change it's size unproportional.
Can anyone confirm that or propose a workaround? If this is true, Apple should definitely change the Keynote help text:
+This transition only works when you use an identical image, shape, or text box in a different location or with a different size on the next slide.+
They should mention, that it only work for proportionally resized shapes, which makes the tool pretty useless for a lot of cases.

The workaround I use is to build slides with 'layers'. I cut my slide in photoshop into pieces and let the graph bar slide in from behind one of those pieces. I's a workaround, I know. And I'd really love to see the next release with build in layers, but with a little creativity and clever thinking you can come up with great results.
