NAME
graph  draw a graph
SYNOPSIS
graph [ a spacing [ start ]] [ b ] [ c string ]
[ g gridstyle ] [ l label ] [ m connectmode ]
[ s ] [ x [ l ] lower [ upper [ spacing ]]]
[ y [ l ] lower [ upper [ spacing ]]]
[ h fraction ] [ w fraction ] [ r fraction ]
[ u fraction ] [ t ] ...
DESCRIPTION
graph with no options takes pairs of numbers from the standard input as
abscissaes and ordinates of a graph. Successive points are connected
by straight lines. The standard output from graph contains plotting
instructions (see plot(5)) suitable for input to plot(1G) or to the
command lpr g (see lpr(1)).
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 con
tain blanks and numbers; labels never contain NEWLINE characters.
A legend indicating grid range is produced with a grid unless the s
option is present.
OPTIONS
Each option is recognized as a separate argument. If a specified lower
limit exceeds the upper limit, the axis is reversed.
a spacing[ start ]
Supply abscissaes automatically (they are missing
from the input); spacing is the spacing (default 1).
start is the starting point for automatic abscissaes
(default 0 or lower limit given by x).
b Break (disconnect) the graph after each label in the
input.
c string String is the default label for each point.
g gridstyle Gridstyle is the grid style: 0 no grid, 1 frame with
ticks, 2 full grid (default).
l label is label for graph.
m connectmode Mode (style) of connecting lines: 0 disconnected, 1
connected (default). Some devices give distinguish
able line styles for other small integers.
s Save screen, do not erase before plotting.
x [ l ] lower [ upper [ spacing ] ]
If l is present, x axis is logarithmic. lower and
upper are lower (and upper) x limits. spacing, if
present, is grid spacing on x axis. Normally these
quantities are determined automatically.
y [ l ] lower [ upper [ spacing ] ]
If l is present, y axis is logarithmic. lower and
upper are lower (and upper) y limits. spacing, if
present, is grid spacing on y axis. Normally these
quantities are determined automatically.
h fraction fraction of space for height.
w fraction fraction of space for width.
r fraction fraction of space to move right before plotting.
u fraction fraction of space to move up before plotting.
t Transpose horizontal and vertical axes. Option x
now applies to the vertical axis.

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.
