PLOT(5) File Formats Manual PLOT(5)
plot - graphics interface
Files of this format are produced by routines described in plot(3X) and plot(3F), and are interpreted for various devices by commands
described in plot(1G). A graphics file is a stream of plotting instructions. Each instruction consists of an ASCII letter usually fol-
lowed by bytes of binary information. The instructions are executed in order. A point is designated by four bytes representing the x and
y values; each value is a signed integer. The last designated point in an l, m, n, a, or p instruction becomes the `current point' for the
next instruction. The a and c instructions change the current point in a manner dependent upon the specific device.
Each of the following descriptions begins with the name of the corresponding routine in plot(3X).
m move: The next four bytes give a new current point.
n cont: Draw a line from the current point to the point given by the next four bytes.
p point: Plot the point given by the next four bytes.
l line: Draw a line from the point given by the next four bytes to the point given by the following four bytes.
t label: Place the following ASCII string so that its first character falls on the current point. The string is terminated by a newline.
a arc: The first four bytes give the center, the next four give the starting point, and the last four give the end point of a circular
arc. The least significant coordinate of the end point is used only to determine the quadrant. The arc is drawn counter-clockwise.
c circle: The first four bytes give the center of the circle, the next two the radius.
e erase: Start another frame of output.
f linemod: Take the following string, up to a newline, as the style for drawing further lines. The styles are `dotted,' `solid,' `long-
dashed,' `shortdashed,' and `dotdashed.' Effective only in plot 4014 and plot ver.
s space: The next four bytes give the lower left corner of the plotting area; the following four give the upper right corner. The plot
will be magnified or reduced to fit the device as closely as possible.
Space settings that exactly fill the plotting area with unity scaling appear below for devices supported by the filters of plot(1G).
The upper limit is just outside the plotting area. In every case the plotting area is taken to be square; points outside may be dis-
playable on devices whose face isn't square.

These functions generate graphics output for a set of output devices. The format of the output is dependent upon which link editor option
is used when the program is compiled and linked (see Link Editor).
The term "current point" refers to the current setting for the x and y coordinates.
The arc() function specifies a circular arc. The coordinates (x0, y0) specify the center of the arc. The coordinates (x1, y1) specify the
starting point of the arc. The coordinates (x2, y2) specify the end point of the circular arc.
The box() function specifies a rectangle with coordinates (x0, y0), (x0, y1), (x1, y0), and (x1, y1). The current point is set to (x1,
The circle() function specifies a circle with a center at the coordinates (x, y) and a radius of r.
The closevt() and closepl() functions flush the output.
The cont() function specifies a line beginning at the current point and ending at the coordinates (x, y). The current point is set to (x,
The erase() function starts another frame of output.
The label() function places the null terminated string s so that the first character falls on the current point. The string is then ter-
minated by a NEWLINE character.
The line() function draws a line starting at the coordinates (x0, y0) and ending at the coordinates (x1, y1). The current point is set to
The linemod() function specifies the style for drawing future lines. s may contain one of the following: dotted, solid, longdashed, short-
dashed, or dotdashed.
The move() function sets the current point to the coordinates (x, y).
The openpl() or openvt() function must be called to open the device before any other plot functions are called.
The point() function plots the point given by the coordinates (x, y). The current point is set to (x, y).
The space() function specifies the size of the plotting area. The plot will be reduced or enlarged as necessary to fit the area specified.
The coordinates (x0, y0) specify the lower left hand corner of the plotting area. The coordinates (x1, y1) specify the upper right hand
corner of the plotting area.
Various flavors of these functions exist for different output devices. They are obtained by using the following ld(1) options:
-lplot device-independent graphics stream on standard output in the format described in plot(4B)
-l300 GSI 300 terminal
-l300s GSI 300S terminal
-l4014 Tektronix 4014 terminal
