# plpoin.3plplot - Man Page

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 (This function is largely superseded by **plstring**(3plplot) which gives access to many[!]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