NAME
dgraph - do a set of graphs to a dumb terminal
SYNOPSIS
dgraph [ -w width ][ -l length ][ +variable value .. ][ file .. ]
DESCRIPTION
Dgraph reads each graph file in sequence and converts it to a character
plot displayable on any ascii device. If no files are given, the
standard input is read.
Across the top of the plot, the extrema are printed. This is the only
indication of the axis size. Curves are represented with their
respective letter (’A’ for curve A, etc.) at each point. Where two or
more curves cross, a number is shown instead.
The size of the output array can be specified as a certain width and
length. The default size is 79 by 22.
Variables can be set explicitly with +variable value options. See
bgraph(1) for details.
EXAMPLE
To get a quick glimpse of the sine function from 0 to 4.
dgraph
A(x)=sin(x)
Anpoints=100
xmin=0
xmax=4
