This message indicates that the RealType in your ScalarMap
occurs in a DataReference already linked to the DisplayImpl.
If possible, addMap() all the ScalarMaps before your
addReference() any Data.
Note also that you cannot add another identical:
ScalarMap( RealType.YAxis, Display.YAxis)

To get different axis scales etc, use different RealTypes
in each Set, each with its own ScalarMap (addMap() all at
the start).

Perhaps Don knows the answer to this.
Good luck,
