If you really want to overlap the graphs, then look at the subplot function in the TeachingDemos package (you would first need to create a blank graph with no or minimal margins, then use subplot to place your graphs within the blank graph).
You may also want to look at the lattice package for doing arrays of graphs with the graph boxes aligning and axes only on the outer plots. -- Gregory (Greg) L.
