GNUPLOT(1) Programmer's Manual GNUPLOT(1)
NAME
gnuplot - an interactive plotting program
SYNOPSIS
gnuplot
DESCRIPTION
_G_N_U_P_L_O_T is a command-driven interactive function plotting
program. Here are some of its features:
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.
User-defined X and Y ranges (optional Y auto-ranging),
smart Y scaling, smart tic marks.
User-defined constants and functions.
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 áEGA and
Corona 325 graphics. Other devices can be added simply, but
will require recompiling.
Shell escapes and command line substitution.
Load and save capability.
Output redirection.
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.

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