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
            ^D
