if you're using omnetpp3.x you can generate graphs with plove ($plove
omnetpp.vec) or scalars ($scalars omnetpp.sca).
With omnet4 there's the "charts" icon to use, after you've generated
a .anf file that includes the .vec and .sca results of your
simulation.
By the way in the manuals of both omnet versions there's a good
explication of this matter.
have a good day,
