      NAME
           graph - draw a graph

      SYNTAX
           graph [ options ]

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

           If the coordinates of a point are followed by a non-numeric
           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 new-lines.

           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 starting 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 (e.g., the Tektronix 4014:
                     2=dotted, 3=dash-dot, 4=short-dash, 5=long-dash).
           -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 argument, 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.
