For this pie chart, we turned off shading with <a class="xref" href="SetShading.html" title="SetShading"><span class="refentrytitle">SetShading</span></a>
to get a flat pie instead of a 3-D look.
We also overrode the default colors with our own array using
<a class="xref" href="SetDataColors.html" title="SetDataColors"><span class="refentrytitle">SetDataColors</span></a>,
and used the same color names to make a legend with <a class="xref" href="SetLegend.html" title="SetLegend"><span class="refentrytitle">SetLegend</span></a>.
Finally, we moved the labels in towards the center with
<a class="xref" href="SetLabelScalePosition.html" title="SetLabelScalePosition"><span class="refentrytitle">SetLabelScalePosition</span></a>.
