The above recommendations describe standalone packages which work on data produced by your code in a separate step. An alternative route is to incorporate the plotting facilities within your program, and the recommended way of doing this is by using the PGPLOT library.
The library, which was written to support astronomical
applications, consists of a collection of high-level
routines for producing plots, maps and images either
on-screen or as Postscript to a file. Refer to SUN/15, PGPLOT --- Graphics
Subroutine Library for further details, or to the
PGPLOT home page at <<>

Note that there are two versions of PGPLOT currently available on Starlink, `native' PGPLOT, and a Starlink version which uses GKS. The latter is being deprecated, with a view to being ultimately phased out, and this will affect how you link your program against the library. At the time of writing (December 1998), the way in which the dual versions will be supported has not been finalised; ask your system manager for advice.
