<p>Some plot types have additional color handling to facilitate easier handling and
differentiation between data sets.</p>
<p>

<p>Pie plots support the concept of color-themes. A color theme is
simple a set of colors used for consecutive slices within the Pie.
How to specify color-themes is further discussed in <a class="xref" href="ch16.html#sec.pie-color-themes" title="Specifying slice colors and using themes">Specifying slice colors and using themes</a>.</p>

<p>Matrix (Only available in the Pro-version) and contour plots also
have the concept of color maps. This is a range of colors used to
indicate the data in the plot. Examples of color maps can be found
in <a class="xref" href="ch22s08.html" title="Built in color maps">Built in color maps</a>. (Color maps are defined
and implemented in
"<code class="filename">jpgraph_colormap.inc.php</code>").</p>
