Updating graphic layers

This is a general question about the best methods to draw features that update within a graphics layer.  For instance, I am interested in drawing a line of sight line that changes direction through time as I move a Q-slider. Should I have a pointer to a graphics overlay that I create a new instance of each time I want to redraw the line?  Or is there a more elegant method for redrawing on a map?
