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  (This function is largely superseded by plstring(3plplot) which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 plotted.

       Redacted form: plpoin(x, y, code)

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

ARGUMENTS

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

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

       y (const 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.
