NAME

       plpoin - Plot a glyph at the specified points

SYNOPSIS

       plpoin(n, x, y, code)

DESCRIPTION

       Plot  a	glyph  at  the	specified  points.   (This  function is largely superseded by plstring(3plplot) which gives access to many[!] more
       glyphs.) code=-1 means try to just draw a point.  Right now it's just a move and a draw at the same place.  Not ideal, since a sufficiently
       intelligent  output  device  may  optimize  it  away, or there may be faster ways of doing it.  This is OK for now, though, and offers a 4X
       speedup over drawing a Hershey font "point" (which is actually diamond shaped and therefore takes 4 strokes to draw).  If 0 <  code  <  32,
       then  a useful (but small subset) of Hershey symbols is plotted.  If 32 <= code <= 127 the corresponding printable ASCII character is plot-
       ted.

       Redacted form: plpoin(x, y, code)

       This function is used in examples 1,6,14,21,29.

ARGUMENTS

       n (PLINT, input)
	      Number of points in the x and y arrays.

       x (PLFLT *, input)
	      Pointer to an array with X coordinates of points.

       y (PLFLT *, input)
	      Pointer to an array with Y coordinates of points.

       code (PLINT, input)
	      Hershey symbol code (in "ascii-indexed" form with -1 <= code <= 127) corresponding to a glyph to be plotted at each of the n points.
