#### `plstring3`: Plot a glyph at the specified 3D points

`plstring3 (` | n ,
| x ,
| y ,
| z ,
| string `)`;

Plot a glyph at the specified 3D points. (Supersedes `plpoin3` because many[!] more glyphs are accessible with `plstring3`.) Set up the call to this function similar to what is done for `plline3`. 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` and `plptex`, 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.

`n` (``PLINT``, input)

  Number of points in the ``x``, ``y``, and ``z`` vectors.

`x` (``PLFLT_VECTOR``, input)

  A vector containing the x coordinates of the points.

`y` (``PLFLT_VECTOR``, input)

  A vector containing the y coordinates of the points.

`z` (``PLFLT_VECTOR``, input)

  A vector containing the z coordinates of the points.

`string` (``PLCHAR_VECTOR``, input)

  A UTF-8 character string containing the glyph(s) to be plotted at each of the ``n`` points. points.

Redacted form: `plstring3(x, y, z, string)`

This function is used in example 18.
