NhlUpdateData

This procedure is used to force one or more DataComm instances to update their internal state to reflect any changes that have occurred in DataItem instances that have been associated with the DataComm instances. (See NhlUpdateData.)

Synopsis

	procedure NhlUpdateData( 
		dcomms[*]:graphic
	)

Description

This procedure is really only useful when the items in dcomms have the resource dcDelayCompute set to True. When this is True, DataComm instances are not notified of changes to their data items. This procedure tells each object in dcomms to check for changes in its data. These data were added with the NhlAddData or added using create or setvalues.
