I want to use the setRange method of ScalarMap to reverse the polarity of an axis, but first I need to know the max and min values of that axis before I can reverse them. I have a GriddedSet being passed into my procedure, which I assign to a DataReference, etc. If I then do a System.out.println on the DataReference, I get a list "DomainDimension 1..."etc. that has the information I need, but I couldn't find what method to call to extract the specific range in the form to use it in code, i.e. to alter and pass on to setRange.
