If I understand you right, you'r going to make a graph, containing lots of
different curves, but want to show different groups of them at different
instances. I'd propose to use Show. Make a list of your plots, each of one
curve, then on any occassion delete those plots you want to suppress and
Show what is left over.

Hope that helps
