Hi John,

Its done a by a call to Data.computeRanges() from
DataRenderer.prepareAction(). As long as you don't call
ScalarMap.setRange(), you can access the range by a call
to ScalarMap.getRange(), after data have been transformed
for display. You can use a DisplayListener to wait for a
DisplayEvent.TRANSFORM_DONE.
Cheers,
Bill
