<h4><a name="shading-aux">8.4.6 <code>aux</code></a></h4>
<p>Paints markers in a colour determined by
the value of an additional data coordinate.
The marker colours then represent an additional
dimension of the plot.
You can also adjust the transparency
of the colours used.
The way that data values are mapped
to colours is usually controlled by options
at the level of the plot itself,
rather than by per-layer configuration.
</p>
<p>
<strong>Usage:</strong>
<pre>
shadingN=aux auxN=<num-expr> auxnullcolorN=<rrggbb>|red|blue|...
opaqueN=<number>
</pre>
</p>
<p>All the parameters listed here
affect only the relevant layer,
identified by the suffix
<code>N</code>.
</p>
<p>
<strong>Example:</strong>
</p>
<div align="center"><img src="plot2-shading-aux.png" alt="" align="middle"></div>
<p><pre> stilts plot2plane layer1=mark in1=dr5qso.fits
<strong>shading1=aux</strong> <strong>aux1=z</strong> <strong>auxmap=plasma</strong>
x1=psfmag_g-psfmag_r y1=psfmag_u-psfmag_g size1=2
xmin=-0.5 xmax=2.5 ymin=-1 ymax=6</pre></p>
<p>Associated parameters are as follows:
<dl>
<dt><strong><code>auxN = <num-expr></code> <em>(String)</em></strong></dt>
<dd>Colour coordinate for Aux shading.
<p>This parameter gives a column name, fixed value, or algebraic expression for the
<code>aux</code> coordinate
for layer <code>N</code>.
The value is a numeric algebraic expression based on column names
as described in <a href="jel.html">Section 10</a>.
</p>
</dd>
<dt><strong><code>auxnullcolorN = <rrggbb>|red|blue|...</code> <em>(<a href="http://docs.oracle.com/javase/6/docs/api/java/awt/Color.html">Color</a>)</em></strong></dt>
<dd>The color of points with a null value of the Aux coordinate,
given by name or as a hexadecimal RGB value.
<p>The standard plotting colour names are
<code>red</code>, <code>blue</code>, <code>green</code>, <code>grey</code>, <code>magenta</code>, <code>cyan</code>, <code>orange</code>, <code>pink</code>, <code>yellow</code>, <code>black</code>, <code>light_grey</code>, <code>white</code>.
However, many other common colour names (too many to list here)
are also understood.
The list currently contains those colour names understood
by most web browsers,
from <code>AliceBlue</code> to <code>YellowGreen</code>,
listed e.g. in the
<em>Extended color keywords</em> section of
the <a href="http://www.w3c.org/TR/css3-color#svg-color">CSS3</a> standard.
</p>
<p>Alternatively, a six-digit hexadecimal number <em>RRGGBB</em>
may be supplied,
optionally prefixed by "<code>#</code>" or "<code>0x</code>",
giving red, green and blue intensities,
e.g. "<code>ff00ff</code>", "<code>#ff00ff</code>"
or "<code>0xff00ff</code>" for magenta.
</p>
<p>If the value is null, then points with a null
Aux
value will not be plotted at all.
</p>
<p>[Default: <code>grey</code>]
</p>
</dd>
<dt><strong><code>opaqueN = <number></code> <em>(Double)</em></strong></dt>
<dd>The opacity of points plotted in the Aux colour.
The value is the number of points which have to be
overplotted before the background is fully obscured.
<p>[Default: <code>1</code>]
</p>
</dd>
</dl>
