Mattheiu, For rescaling when your data range is known, use:
a1_dbz_PiecewiseFunction.RescaleTransferFunction(min, max) a1_dbz_PVLookupTable.RescaleTransferFunction(min, max) When it is unknown, you can use pipelineObject = GetActiveSource() display = GetDisplayProperties(pipelineObject) display.RescaleTransferFunctionToDataRange(False) You can change the False argument to True in the second line if you want the rescaling to only extend the current range instead of possibly shrinking it.
