NAME
       plot - 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.

       4014            space(0, 0, 3120, 3120);



       ver             space(0, 0, 2048, 2048);



       300, 300s       space(0, 0, 4096, 4096);



       450             space(0, 0, 4096, 4096);
