plot(4B) SunOS/BSD Compatibility Package File Formats plot(4B)NAMEplot - graphics interface
DESCRIPTION
Files of this format are interpreted for various devices by commands
described in plot(1B). A graphics file is a stream of plotting instruc‐
tions. Each instruction consists of an ASCII letter usually followed 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, or
p instruction becomes the ``current point'' for the next instruction.
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 plot(1B).
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,'' ``longdashed,'' ``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(1B). 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.
