Vic, According to the documentation, 'Currently, the only display attribute available for the export tag is display="class:ucar.unidata.idv.control.ObsListControl" or an ID of a display control that refers to an instance of the ObsListControl (e.g. a Point Data List display for METAR data).' http://www.unidata.ucar.edu/software/idv/docs/userguide/isl/DataAndDisplays.html So I interpret from the documentation that this functionality is currently not possible for gridded data. We are looking into implementing this functionality for gridded data. A possible workaround would be to use Jython to achieve your objectives.
