PLPOIN(3plplot) 						    PLplot API							   PLPOIN(3plplot)

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   (This  function is largely superseded by plstring(3plplot) which gives access to many[!]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.

NAME

       plstring - Plot a glyph at the specified points

SYNOPSIS

       plstring(n, x, y, string)

DESCRIPTION

       Plot  a	glyph  at  the	specified  points.  (Supersedes plpoin(3plplot) and plsym(3plplot) because many[!] more glyphs are accessible with
       plstring(3plplot).) The glyph is specified with a PLplot user string.  Note that the user string is not actually limited to one glyph so it
       is  possible (but not normally useful) to plot more than one glyph at the specified points with this function.  As with plmtex(3plplot) and
       plptex(3plplot), the user string can contain FCI escapes to determine the font, UTF-8 code to determine the glyph or  else  PLplot  escapes
       for Hershey or unicode text to determine the glyph.

       Redacted form: plstring(x, y, string)

       This function is used in examples 4 and 26.

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.

       string (const char *, input)
	      PLplot user string corresponding to the glyph to be plotted at each of the n points.
