.TH GBPLOT "1" "March 2019" "gbplot ver. 5.6" "User Commands"
.SH NAME
gbplot \- gnuplot command line interface
.SH SYNOPSIS
.B gbplot
[\fI\,options\/\fR] [\fI\,command\/\fR] [\fI\,specstring\/\fR] \fI\,< datafile\/\fR
.SH DESCRIPTION
This command produce simple plots from the command line using the
\&'gnuplot' program. 'comand' is one of the gnuplot commands: 'plot' or
\&'splot' while 'specstring' is a list of gnuplot specifications. In
order to escape shell interpretation place 'specstring' between double
quotes. It is possible to specify the type of terminal and output file
name as command line options. It is also possible to start an
interactive session, useful to adjust plot parameters by hand. The
program can be used in a shell pipe, as in
.PP
cat datafile | gbplot [options] [command] [specstring]
