PLOT(5) UNIX Programmer's 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 dev- ices by commands described in plot(1G). 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. 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 li
