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
