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 (This function is largely superseded by**plstring**(3plplot) which gives access to many[!]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