Library /sys$common/syshlp/basichelp.hlb Graphics, PLOT  *Conan The Librarian (sorry for the slow response - running on an old VAX)

  The PLOT statement draws the specified graphics  object  on  all  active
  devices.  Values for graphics attributes such as color and style use the
  current settings.  Graphics objects displayed with PLOT  from  within  a
  picture,  are affected by the specified transformation function, whereas
  those points displayed with GRAPH are not.  The  PLOT  POINTS  statement
  must  include  the  coordinates  for  at least one point.  The PLOT AREA
  statement requires a minimum of three points.  However,  with  the  PLOT
  LINES  statement,  you  have  the  option  of including no points or any
  number of points.

  The PLOT LINES statement lets you control whether the beam of  light  is
  switched  on  or  off.   When  the  beam of light is switched off, it is
  possible to move a plotter from one position to another without  leaving
  a  trail  or  a  line.  When the beam of light is switched on, a plotter
  draws a line as it moves from one position to the next.  At the start of
  program  execution,  the  beam  of  light is off.  To leave the beam on,
  place a semicolon at the end  of  the  last  point  in  the  PLOT  LINES
  statement.   To turn the beam off, use a PLOT LINES statement and do not
  include points or a semicolon after the last point.

  Example

   OPTION TYPE = EXPLICIT
   DECLARE SINGLE counter
   SET WINDOW 0,2*PI,-1,1
   SET LINE SIZE 5
   FOR counter = 0 TO 2*PI STEP 0.1
     PLOT LINES counter, SIN(counter);
   NEXT counter
   PLOT LINES
   END
