Once I used a slightly different effect in Keynote 1: showing a  
scatter plot of experimental data points, and then adding on top of  
it a theoretical curve (or fit, for that matter).

This was done simply by using transitions in Keynote itself: having  
the two plots (scatter plot, without and with the theoretical curve)  
in two slides at exactly the same position, and using the Dissolve  
transition between the slides.

I haven't used Keynote 2 much since getting it, but with its added  
functionalities I imagine things could be even simpler: setting maybe  
a transition for the plot object itself, without needing to use 2  
different slides.
