     arc(x, y, x0, y0, x1, y1)



     dot(x, y, dx, n, pattern)

     int pattern[ ];



     move(x, y)

DESCRIPTION

     These subroutines generate graphic output  in  a  relatively

     device-independent  manner.  See plot (VI) for a description

     of the meaning of the subroutines.



     There are four libraries containing these routines, one that

     produces  general  graphics commands on the standard output,

     and one each for the vt0 storage scope, the Diablo  plotting

     terminal  and  the  Tektronix 4014 terminal.  Openpl must be

     used before any  of  the  others  to  open  the  device  for

     writing.  Closepl flushes the output.



FILES

     /usr/lib/plot.a produces output for plotting filters

     /usr/lib/vt0.a  produces output on vt0 storage scope

     /usr/lib/gsip.a produces output on Diablo terminal

     /usr/lib/tek.a  produces  output  for  the  Tektronix   4014

     terminal
