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 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.

     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,''    ``short-
           dashed,''  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

           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.
