PLOT(VI)                     6/4/73                      PLOT(VI)


     plot - make a graph


     plot [ option ] ...


     Plot takes pairs of  numbers  from  the  standard  input  as

     abscissas and ordinates of a graph.  The graph is plotted on

     the storage scope, /dev/vt0.

     The following options are recognized,  each  as  a  separate


     a     Supply abscissas automatically (they are missing  from

          the  input);  spacing is given by the next argument, or

          is assumed to be 1 if next argument is not a number.

     c     Place character string given by next argument at  each


     d     Omit connections between points. (Disconnect.)

     gn    Grid style:

          n=0, no grid

          n=1, axes only

          n=2, complete grid (default).

     s     Save screen, don't erase before plotting.

     x     Next 1 (or  2)  arguments  are  lower  (and  upper)  x


     y     Next 1 (or  2)  arguments  are  lower  (and  upper)  y


     Points are connected by straight line segments in the  order

     they  appear  in  input.  If a specified lower limit exceeds

     the upper limit, or if the automatic increment is  negative,

     the graph is plotted upside down.  Automatic abscissas begin

     with the lower x limit, or with 0 if no limit is  specified.

     Grid lines and automatically determined limits fall on round

     values, however roundness may  be  subverted  by  giving  an

     inappropriately   rounded  lower  limit.   Plotting  symbols

     specified by c are placed so that a  small  initial  letter,

     such  as  +  o  x,  will  fall approximately on the plotting





     spline (VI), plog (VI)


     A limit of 1000 points is enforced silently.
