# graph(ADM)

**graph --
draw a graph
**

## Syntax

**graph** [ *options* ]
## Description

The **graph** command 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**(ADM)
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 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 starting 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 (for example, the Tektronix 4014: 2=dotted,
3=dash-dot, 4=short-dash, 5=long-dash).

**-s**-
Save screen, do 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.
(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.

## Limitations

The **graph** command 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.
