# plpoin3.3plplot - Man Page

Plot a glyph at the specified 3D points

## Synopsis

**plpoin3**(*n*, *x*, *y*, *z*, *code*)

## Description

Plot a glyph at the specified 3D points. (This function is largely superseded by **plstring3**(3plplot) which gives access to many[!] more glyphs.) Set up the call to this function similar to what is done for **plline3**(3plplot). *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: **plpoin3(x, y, z, code)**

This function is not used in any example.

## 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.

*z*(**PLFLT_VECTOR**(3plplot), input)A vector containing the z 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.
