NAME

6       plpoin - Plot a glyph at the specified points
7

SYNOPSIS

9       plpoin(n, x, y, code)
10

DESCRIPTION

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

23       Redacted form: plpoin(x, y, code)

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

ARGUMENTS

28       n (PLINT(3plplot), input)
29              Number of points in the x and y vectors.
30
31       x (PLFLT_VECTOR(3plplot), input)
32              A vector containing the x coordinates of points.
33
34       y (PLFLT_VECTOR(3plplot), input)
35              A vector containing the y coordinates of points.
36
37       code (PLINT(3plplot), input)
38              Hershey symbol code (in "ascii-indexed" form with -1 <= code  <=
39              127)  corresponding  to  a  glyph to be plotted at each of the n
40              points.
