.SH NAME
gnutex \- an interactive plotting program with LaTeX support
.SH SYNOPSIS

.SH DESCRIPTION
.I Gnutex
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 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.  LaTeX is supported as
described below. 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.
.PP 
By default, gnutex does not place labels on plots.  However, with
the 
.B \-l
option, they will be printed. The plot may have an optional additional title.
.PP
When using the "tek40xx", "toptek", or "bottek" terminal type, gnutex
will clear the screen before plotting.  The 
.B \-p
option will disable the pre-plot screen clear.  This is useful mainly
when the output of gnutex is being sent to a printer, where clearing
the screen translates into printing a blank page.
.PP
The 
.B \-x
option enables debugging output, in case anyone wants to play with 
personal enhancements.
.PP
Support for a LaTeX "terminal" driver, which supports all normal
gnuplot plotting commands plus labeling tic marks, title and axes
labels, arbitrary labels with arrows, user-defined line styles, and
keys.

.SH BUGS
The unixplot driver automatically writes to stdout, so you have to
redirect the gnutex's output from the shell.
