You can reverse an axis by using the setRange method of the ScalarMap to that axis. ScalarMap sm = new ScalarMap(myRangeType, Display.YAxis); myDisplay.addMap(sm); ... double[] range = sm.getRange(); sm.setRange(range[1], range[0]); Hope that helps, Doug Edward Stanford wrote: > > Hello, all. > > I have a 2D data set (pressure versus temperature), which I wish to display > with pressure on the Y-Axis.
