GRAPH(1G) UNIX Programmer's Manual GRAPH(1G)

NAME

    graph - draw a graph

SYNOPSIS

    graph [ option ] ...

DESCRIPTION

    _G_r_a_p_h 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 _p_l_o_t(1)
    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

    _G_r_a_p_h 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.
