    NAME
         graph - draw a graph

    SYNOPSIS
         graph [ option ] ...

    DESCRIPTION
         Graph with no options takes pairs of numbers from the stan-
         dard input as abscissas and ordinates of a graph.	Succes-
         sive points are connected by straight lines.  The graph is
         encoded on the standard output for display by the plot(1G)
         filters.

         If the coordinates of a point are followed by a nonnumeric
         string, that string is printed as a label beginning on the
         point.  Labels may be surrounded with quotes "...", in which
         case they may be empty or contain blanks and numbers; labels
         never contain newlines.

         The following options are recognized, each as a separate
         argument.

         -a   Supply abscissas automatically (they are missing from
    	  the input); spacing is given by the next argument
    	  (default 1).	A second optional argument is the start-
    	  ing point for automatic abscissas (default 0 or lower
    	  limit given by -x).

         -b   Break (disconnect) the graph after each label in the
    	  input.

         -c   Character string given by next argument is default
    	  label for each point.

         -g   Next argument is grid style, 0 no grid, 1 frame with
    	  ticks, 2 full grid (default).

         -l   Next argument is label for graph.

         -m   Next argument is mode (style) of connecting lines: 0
    	  disconnected, 1 connected (default).	Some devices give
    	  distinguishable line styles for other small integers.

         -s   Save screen, don't erase before plotting.

         -x [ l ]
    	  If l is present, x axis is logarithmic.  Next 1 (or 2)
    	  arguments are lower (and upper) x limits.  Third argu-
    	  ment, if present, is grid spacing on x axis.	Normally
    	  these quantities are determined automatically.

         -y [ l ]

    	  Similarly for y.

         -h   Next argument is fraction of space for height.

         -w   Similarly for width.

         -r   Next argument is fraction of space to move right before
    	  plotting.

         -u   Similarly to move up before plotting.

         -t   Transpose horizontal and vertical axes.  (Option -x now
    	  applies to the vertical axis.)

         A legend indicating grid range is produced with a grid
         unless the -s option is present.

         If a specified lower limit exceeds the upper limit, the axis
         is reversed.

    BUGS
         Graph stores all points internally and drops those for which
         there isn't room.
         Segments that run out of bounds are dropped, not windowed.
         Logarithmic axes may not be reversed.
