hs_plot::copy Copy an hs_plot structure to a new location. Usage: newid = plid -> copy([target]) Argument target object An existing hs_plot object to have its values changed. Keywords: verbose If set, then print messages if there are any problems with the copy top input objref An object reference to which the copy is to be reparented. Notes: Relies on the fact that struct_assign works on object references (is this stable?). If an argument is given, then the return value is meaningless. History: Original: 30/11/99; SJT Add the copy to existing option: 1/12/99; SJT Add top keyword: 20/5/02
