Oops, I misinterpreted your question as looking for something like lonMap.setRange(-180, 180). You want the same range setRange(0, 360), but you just want the numbers greater than 180 to be labeled negative. If you use setRange(0, 360) it should put the negative values in the right place (i.e., add 360 to their values), but the labels will be positive. You can override the labels with the AxisScale.setLabelTable() method. So perhaps lonMap.setRange(0, 360) and setLabelTable() will solve your problem? A CS mapping (0->180, -180->0) to (0, 360) is that it will have a discontinuity which is lilely to cause trouble. Let us know if this will will work. Cheers, Bill
