Radiance dgraph program
DGRAPH(1) DGRAPH(1)
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 stan-
dard 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 respec-
tive 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.

A(x)=sin(x)
Anpoints=100
xmin=0
xmax=4
