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 stan-
dard input as abscissaes and ordinates of a graph. Succes-
sive points are connected by straight lines. The standard
output from graph contains plotting instructions suitable
for input to plot(1B) or to the command lpr -g (see
lpr(1B)).
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 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
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.
