Thanks for the suggestion, that's a useful altenative. I've done it now like you proposed...

However, you could accomplish something like this by printing the iso-level in a Swing label in the same frame with your DisplayImpl. Or you may even put the iso-level in a Real object that you add to the Display, mapped to Text and possibly with screen location given by ConstantMaps or other Reals combined in a RealTuple with the iso-level Real.
