graphics: REPRESENTATION


item

Items are the basic components of the plot. All components that occur in the plots produced by the Fortran portion of the program are predefined. For plots made from the procedure executor, a utility routine will be provided to add items.

In the list below, no distinction is made between the primitives via which the items are plotted. The distinction is important though when you update.
