Reversing Axes in 2D plots

[Edward Stanford <stanford@xxxxxxx>]

Hello, all.

I have a 2D data set (pressure versus temperature), which I wish to display 
with pressure on the Y-Axis.  Using the obvious

            myDisplay.addMap(new ScalarMap(myRangeType, Display.XAxis));
            myDisplay.addMap(new ScalarMap((RealType), 
myDomainType.getComponent(0),Display.YAxis));

produces almost what I want: at the origin, the pressure coordinate has the 
lowest value in the data set, and at the top, it has the highest.

This is certainly the expected behavior for a generic data set, but it is a 
trifle unphysical in reference to an atmosphere, where the highest 
pressures occur at the "lowest" point.

Is there any obvious way to invert the scales of a scalar map?  I didn't 
see one in the javadoc, but that doesn't mean it isn't there.
