Usage

ng_set_size(obj, dataName) <- value

Arguments

obj	A navgraph handler of an active navGraph session.
dataName	String of the data name. If not specified and only one data set is beeing used in the navGraph session, it will default to this data. Otherwise, if multiple data sets are being used in a navGraph session, the function will list the name of these data sets and ask you to specify one.
