I think what you are looking for is something along these lines..
you can pass the data as an array to RRDs::graph, so instead of doing something like...
my ($avg,$xsize,$ysize) = RRDs::graph "-","--title", "Bits Graph","--height","300",,,,etc,,etc,;
you can do
my @array = ("-","--title", "Bits Graph","--height","300",,,etc,,,);
and then any combination of iteration or selection you like
and then do...
my ($avg,$xsize,$ysize) = RRDs::graph @array;
does that make sense?
