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   (This  function  is  largely  superseded  by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, and 29.

ARGUMENTS

       n (PLINT(3plplot), input)
              Number of points in the x and y vectors.

       x (PLFLT_VECTOR(3plplot), input)
              A vector containing the x coordinates of points.

       y (PLFLT_VECTOR(3plplot), input)
              A vector containing the y coordinates of points.

       code (PLINT(3plplot), 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.
