graphs that use multiple RRD files as input

I have a graph setup on a custom test that is using multiple RRD files as input. The graph is working but it is combining all the RRDs into a single graph instead of splitting them up like the built in "disk" graphs.

Is there a parameter missing in my graphs.cfg definition or some other place I need to modify in order to have Xymon automatically split the graph up into multiple graphs?

Thanks
Steve
