.TH PLOT 5 "15 January 1983"
plot \- graphics interface
Files of this format are produced by routines
and are interpreted for various devices
A graphics file is a stream of plotting instructions.
Each instruction consists of an ASCII letter
usually followed by bytes of binary information.
The instructions are executed in order.
The last designated point in an
instruction becomes the `current point'
for the next instruction.
Each of the following descriptions begins with the name
of the corresponding routine in
move: The next four bytes give a new current point.
cont: Draw a line from the current point to
the point given by the next four bytes.
point: Plot the point given by the next four bytes.
line: Draw a line from the point given by the next
four bytes to the point given by the following four bytes.
label: Place the following ASCII string so that its
first character falls on the current point.
The string is terminated by a newline.
The first four bytes give the center, the next four give the
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.
The first four bytes give the center of the circle,
erase: Start another frame of output.
linemod: Take the following string, up to a newline,
as the style for drawing further lines.
`solid,' `longdashed,' `shortdashed,' and `dotdashed.'
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
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 isn't square.
