This works pretty good. But when I change the first Dimension of the Linear2DSet from [-180, 180] to [-190, 190] I have the same problem than before. And I have another related problem with the RealType.Longitude which I think is really curious. If I make a slicer along the Longitude-Axis so that I can make Latitude-Altitude-Slices and move the slice over the magic 180deg-border the slicer shows the right behaviour. But if I go even further the slicer is wrapped to the other side of the Longitude-Axis. I could understand this if it would happen at 180deg but it happens at 216deg!? What does this mean? The handle of my slicer is not wrapped to the other side. Only the slicer itself shows this behaviour. Please have a look at the attached code for an example. There I set the axis-range with scalarMap.setRange(). But the behaviour is the same if the range is set automatically because of the dataset. Thanks a lot for your good work and your help, Mathias
