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.
