New Releases
CUG334 GNUPLOT
Written by Thomas Williams, Colin Kelley, modified by Russell Lang, Dave Kotz, John Campbell, and submitted by Henri de Feraudy (France), GNUPLOT v2.0 is a command-driven interactive function plotting program. By typing commands interactively or loading a text file that contains commands, user can draw graphs or plot data points on screen in a given graphics mode or printer using a given printer driver. GNUPLOT provides a set of commands: loading/saving command file, plotting a function(built-in or user-defined) or data files, printing a title, label or arrow on a graph, clipping data points, specifying graphics mode (CGA, EGA, VGA if PC), line style, grid, ranges, offset, scaling size, sampling rate, polar/rectangular coordinate, turning on/off auto-axis scaling or auto-tic marks, output redirection, online help, and escaping to shell.Built-in mathmatical functions are the same as the corresponding function in UNIX math library, except that all functions accept integer, real, and complex arguments. The sgn function is also supported as in BASIC.
GNUPLOT supports the following graphics drivers: AED 512, AED 767, BBN BitGraph, Roland DXY800A, EEPIC, Epson LX-800, Fig, HP2623, HP2648, HP75xx, HPGL, IBM Proprinter, Imagen, Iris4D, Kermit-MS, LaTeX, NEX CP6 pinwriter, PostScript, QMS QUIC, ReGis (VT125 and VT2xx), Selanar, Tek 401x, Vectrix 384, and UNIXplot. For the PC version, it supports IBM CGA, EGA, MCGA, VGA, Hercules, ATT 6300, and Corona 325 graphics.
The disk includes a complete set of C source files for the program and graphics drivers, makefile for UNIX, Microsoft C and Turbo C, documentation, demo command files (Fig 1 - 4), and an MS-DOS executable file (compiled under Turbo C). The program is compiled under UNIX, VMS, MS-DOS (using Microsoft C or Turbo C).
