plot@vu-vlsi.UUCP (PLOT project administrators) (11/20/86)
Many of you have reported a problem with part 3 of the 4 shar files
we posted. As a result of neglecting to remove excess characters added
to the PC-clone specific files by XMODEM, shar does complain, however,
I have been assured that these files will work properly regardless of
this problem.
Some of you complained that part 3 never even made it to your system!
Due to the volume of response, and the relatively small size of the
file we've decide to repost shar file #3 of 4. Thank you for your patience.
-Thomas Williams
We tried soooo hard to make it work, but where are the lumps!?

GNUPLOT has been tested on a Pyramid 90x (ucb 4.2 and att V),
a VAX 8200 (VMS 4.3), IBM PC's and AT's (MS-DOS 3.1, Microsoft C 4.0).
The code is written with portability in mind, and it passes lint!
If you have problems, send mail to vu-vlsi!plot. And please send
any modifications you make so they can be #ifdef'd into later releases.
These #defines should be checked before compilation:
VFORK Makefile define if you've got vfork() system call
vms Makefile define if compiling under VMS;
automatically defined by DEC C
PC Makefile define if compiling on a PClone
MSDOS Makefile define if compiling under MSDOS;
automatically defined by Microsoft C 4.0
AED Makefile define these if you want this terminal driver
HP75 . included
QMS .
REGIS .
TEK .
UNIXPLOT .
CGA . same, but only if PC is defined
CORONA .
EGA .
HUGE plot.h define to be largest double if not defined
in <math.h>
HELP plot.h program run by 'help' command
SHELL plot.h default shell to spawn if SHELL environment
variable not found at run-time
To compile:
under UNIX: type 'make'
under VMS: type '@compile', then '@link'. Use the 'vmshelp.csh' script
to convert the help files. If you don't have access to a Unix machine,
send us mail and we'll send you the VMS GNUPLOT.HLB.
under MSDOS: use 'make make.msc' for Microsoft C 4.0. If you've got
another compiler, you're on your own!

.UC 4
.SH NAME
gnuplot \- an interactive plotting program
.SH SYNOPSIS
.B gnuplot
.br
.SH DESCRIPTION
.I GNUPLOT
is a command-driven interactive function plotting program.
Here are some of its features:
.PP
Plots any number of functions, built up of C operators, C library
functions, and some things C doesn't have like **, sgn(), etc. Also
support for plotting scatter-plots of data files for comparing actual
data to theoretical curves.
.PP
User-defined X and Y ranges (optional Y auto-ranging), smart Y scaling,
smart tic marks.
.PP
User-defined constants and functions.
.PP
Support through a generalized graphics driver for ReGis (VT125 and VT2xx),
Tek 401x, AED 767, HP plotters, and QMS laser printers. The PC version
supports IBM CGA & EGA and Corona 325 graphics. Other devices can be added
simply, but will require recompiling.
.PP
Shell escapes and command line substitution.
.PP
Load and save capability.
.PP
Output redirection.
.PP
All computations performed in the complex domain. Just the real part is
plotted by default, but functions like imag() and abs() and arg() are
available to override this.
.SH AUTHORS
Colin Kelley and Tom Williams (vu-vlsi!plot)
.SH BUGS
The unixplot driver automatically writes to stdout, so you have to
redirect the gnuplot's output from the shell.
