PLOT(4) INTERACTIVE UNIX System PLOT(4)
NAME
plot - graphics interface
DESCRIPTION
Files of this format are produced by routines described in
plot(3X) and are interpreted for various devices by commands
described in tplot(1G). A graphics file is a stream of
plotting instructions. Each instruction consists of an
ASCII letter usually followed by bytes of binary informa-
tion. 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, or p instruction becomes the ``current
point'' for the next instruction.
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 [see tplot(1G)].
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 new-line.
e erase: Start another frame of output.
f linemod: Take the following string, up to a new-line, as
the style for drawing further lines. The styles are
``dotted'', ``solid'', ``longdashed'', ``shortdashed'',
and ``dotdashed''. Effective only for the -T4014 and
-Tver options of tplot(1G) (TEKTRONIX 4014 terminal and
VERSATEC plotter).
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 tplot(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 displayable on devices
whose face is not square.

WARNING
The plotting library plot(3X) and the curses library
curses(3X) both use the names erase() and move(). The
curses versions are macros. If you need both libraries, put
the plot(3X) code in a different source file than the
curses(3X) code, and/or #undef move() and erase() in the
plot(3X) code.
