GRAPH(1G)                            SysV                            GRAPH(1G)



NAME
     graph - draw a graph

SYNOPSIS
     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(1G) 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 can be
     surrounded with quotes ", in which case they may be empty or contain
     blanks and numbers; labels never contain new-lines.

OPTIONS
     The following options are recognized, each as a separate argument:

     -a        Supplies 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        Breaks (disconnects) 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        Saves screen, does not 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.  (-x now applies to the
               vertical axis.)

     A legend indicating grid range is produced with a grid unless -s 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 is no
     room.
     Segments that run out of bounds are dropped, not windowed.
     Logarithmic axes may not be reversed.
