</h2>
<p style="margin-left:11%; margin-top: 1em"><b>psxyz</b>
reads (x,y,z) triplets from <i>files</i> [or standard input]
and generates <i>PostScript</i> code that will plot lines,
polygons, or symbols at those locations in 3-D. If a symbol
is selected and no symbol size given, then <b>psxyz</b> will
interpret the fourth column of the input data as symbol
size. Symbols whose <i>size</i> is <= 0 are skipped. If
no symbols are specified then the symbol code (see
<b>−S</b> below) must be present as last column in the
input. Multiple segment files may be plotted using the
<b>−m</b> option. If <b>−S</b> is not used, a
line connecting the data points will be drawn instead. To
explicitly close polygons, use <b>−L</b>. Select a
fill with <b>−G</b>. If <b>−G</b> is set,
<b>−W</b> will control whether the polygon outline is
drawn or not. If a symbol is selected, <b>−G</b> and
<b>−W</b> determines the fill and outline/no outline,
respectively. The <i>PostScript</i> code is written to
standard output.</p>

inch, or m, depending on the <b><A HREF="gmtdefaults.html#MEASURE_UNIT">MEASURE_UNIT</A></b> setting in
.gmtdefaults4, but this can be overridden on the command
line by appending <b>c</b>, <b>i</b>, or <b>m</b> to the

<h2>BUGS
<a name="BUGS"></a>
</h2>
<p style="margin-left:11%; margin-top: 1em">No hidden line
removal is employed for polygons and lines. Symbols,
however, are first sorted according to their distance from
the viewpoint so that nearby symbols will overprint more
distant ones should they project to the same x,y position.
<b><br>
psxyz</b> cannot handle filling of polygons that contain the
south or north pole. For such a polygon, make a copy and
split it into two and make each explicitly contain the polar
point. The two polygons will combine to give the desired
effect when filled; to draw outline use the original
polygon. <br>
The <b>−N</b> option does not adjust the BoundingBox
information so you may have to post-process the
<i>PostScript</i> output with <b>ps2raster -A</b> to obtain
the correct BoundingBox.</p>
