NAME

       plot - graphics interface

DESCRIPTION

       Files  of  this	format	are  produced  by  routines described in plot(3), and are interpreted for various devices by commands described in
       plot(1).  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, or p instruction becomes the `current point' for the next instruction.

       Each of the following descriptions begins with the name of the corresponding routine in plot(3).

       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(1).

       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,' `long-
	  dashed,' `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(1).  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.

	  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);
