C.B. Selleck, Matthew Sears · OSTI OAI (U.S. Department of Energy Office of Scientific and Technical Information) · 1983
PLT is a device independent plotting package developed under the ARIES project in Department 1530. It is built on top of the Sandia Virtual Device Interface (VDI) and therefore supports many different devices. The capabilities of the package include basic plotting primitives, clipping subroutines, color, element plotting routines, software and hardware text, two dimensional graph plotting, mapping subroutines and routines to set various PLT parameters. PLT is coded in RATFOR, a FORTRAN preprocessor and is currently supported on VAX/VMS.
