SM

SM--formerly SuperMongo--is a plotting package that can be run either interactively or by calling subroutines from FORTRAN code. The package was written by Robert Lupton and Patricia Monger. SM is distantly related to, but not compatible with, the original Mongo, described below. SM is available on the VMS Science Cluster and is invoked by typing the SM command.

SM has two modes. In the interactive mode, commands are entered to read data from files and plot the results. In subroutine mode, graphics functions can be called from your C or FORTRAN program. Device drivers are available for a wide variety of terminals, windowing systems, and printers--including Encapsulated PostScript.

A manual (called SM, by Robert Lupton and Patricia Monger) is available in the Science Software Support Office.

Mongo

Mongo is an interactive graphics program written by John Tonry. Most graphics terminals and laser printers at the Institute support Mongo. Workstation users must use a Tektronix emulator, such as an xterm window, since there is no X11 driver. PostScript (not Encapsulated PostScript) output files can be saved by using the locally added hardkeep command instead of the hardcopy command.

Mongo has several modes. In the interactive mode commands are entered to produce a plot on a terminal display. In interpretive mode, one of your programs calls an interpreter and passes it commands. In subroutine mode you program bypasses the interpreter and directly calls graphics subroutines.

Chapter 1 of the STScI Software Guide covers Mongo; it provides setup instructions and a wide range of useful applications. Other documentation is available in the Science Software Support Office. The two most important documents are: MONGO: An Interactive Graphics Program, by John Tonry, and STScI MONGO User's Guide, by Jeffrey Hayes.

PGPLOT

PGPLOT is a graphics subroutine package written by Tim Pearson at Caltech. It has no interactive mode. PGPLOT supports a wide range of output devices including various terminals and printers. The routines are written in FORTRAN-77 and are callable from other languages, such as C.

Chapter 3 of the STScI Software Guide explains how to create specialized plots in PGPLOT and how to do PostScript Cross-hatching for plots. Copies of the PGPLOT manual and the STScI Software Guide are available in the Science Software Support Office.

NCAR

The NCAR library was produced by the National Center for Atmospheric Research as a collection of FORTRAN 77 programs and subroutines used to generate and plot graphs of scientific data. NCAR utilities will:

Users who want to use the NCAR Graphics Library should read the NCAR Graphics Users Manual, which is available in the Science Software Support Office. Chapter 2 of the STScI Software Guide provides setup instructions and an explanation of how to use the routines for common tasks.
