PROGRAM:
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

A(x)=sin(x)
Anpoints=100
