PGPOINT

If you wish to plot discrete points rather than a continuous curve, then use the subroutine pgpoint in place of pgline. The syntax is:

      call pgpoint(npts,x,y,symbol)

where symbol is an integer describing the type of symbol to be used in marking the points. For example, symbol=1 gives you a dot, symbol=2 a plus sign, symbol=3 an asterisk, symbol=4 a circle and symbol=5 a cross.
