Introduction

The PGPLOT library consists of two major parts: a device-independent part, which is written in portable Fortran-77, and a set of device-dependent ``device handler'' subroutines for output on various terminals, image displays, dot-matrix printers, laser printers, and pen plotters. The majority of these device handlers have been contributed by users outside Caltech.

PGPLOT itself is written mostly in standard Fortran-77, with a few non-standard, system-dependent subroutines. It has been tested under several varieties of UNIX (including Linux, SunOS, Solaris, HPUX, AIX) and VMS (both VAX and AXP). Through the kind contributions of PGPLOT users, PGPLOT is also available for a number of other operating systems (NeXTstep, DOS, Windows, Windows/NT, Macintosh OS), although I am unable to support these versions myself. Anyone who is planning to port PGPLOT to other operating systems, compilers, or hardware configurations is advised to contact me first.

Interactive Drawing Programs Based on PGPLOT

• GENPLOT by Dale Gary.
• PGPERL by Karl Glazebrook. This package provides an interface between the Perl language and the PGPLOT FORTRAN library. For further information, see the WWW page http://www.ast.cam.ac.uk/~kgb/pgperl.html.
• PONGO by Paul Harrison. This is supported by Starlink: see http://star-www.rl.ac.uk/. Starlink also maintains a version of PGPLOT layered on the GKS library.
• QDP/PLT by Allyn Tennant. PLT is an interactive plotting and fitting subroutine layered on PGPLOT, and QDP provides a command interface to this routine. QDP/PLT is used by some tasks within the FTOOLS package available from the NASA Laboratory for High Energy Astrophysics.
• STAP by Mingsheng Han. STAP is an interactive command driven statistic and plotting program: for information, see http://www.astro.wisc.edu/~han/stap/stap.html.
• TCL interfaces for PGPLOT have been developed by two groups:
  • Nick Elias of the US Naval Observatory has released ptcl, a package that registers PGPLOT functions as tcl commands. Information is available at ftp://fornax.usno.navy.mil/dist/ptcl/ptcl.html.
  • The Sloan Digital Sky Survey project has developed a TCL interface to PGPLOT as part of its SHIVA package. See the Shiva Home Page for a description of the interface (under ``TCL interface''). For more information contact Eileen Berman.
• WIP by James Morgan. WIP is an interactive package with a simple to use interface designed to produce high quality graphical output. WIP was developed as part of the Berkeley-Illinois-Maryland Association (BIMA) project. For further information, see the WWW page http://bima.astro.umd.edu/bima/wip/wip.html.
