<code class="function">SetPieLabelColor</code> sets the color which is used for data
labels on pie charts.
    </p></div><div class="refsect1"><a id="idp1378477724"></a><h2>Parameters</h2><div class="variablelist"><dl class="variablelist"><dt><span class="term"><em class="replaceable"><code>$color</code></em></span></dt><dd><p>
Color value to use.
See <a class="xref" href="conc-colors.html" title="3.5. Colors">Section 3.5, &#8220;Colors&#8221;</a> for more on color values.
          </p></dd></dl></div></div><div class="refsect1"><a id="idp1378479580"></a><h2>Notes</h2><p>
If <code class="function">SetPieLabelColor</code> is not used, pie chart data labels are
drawn using the text color set with <a class="xref" href="SetGridColor.html" title="SetGridColor"><span class="refentrytitle">SetGridColor</span></a>.
If neither <code class="function">SetPieLabelColor</code> nor
<code class="function">SetGridColor</code> is used, the default color is black.
    </p><p>
See also <a class="xref" href="conc-labels.html" title="3.6. Labels">Section 3.6, &#8220;Labels&#8221;</a> for information about different
label types.
    </p><p>
PHPlot has a deprecated function called <code class="function">SetLabelColor</code>.
Do not use this function. It does not set the color used for labels.
    </p></div><div class="refsect1"><a id="idp1378482996"></a><h2>History</h2><p>
This function was added in PHPlot-5.7.0. In earlier releases, the pie chart
data labels used the color set with <a class="xref" href="SetGridColor.html" title="SetGridColor"><span class="refentrytitle">SetGridColor</span></a>, which
also sets the color of other elements. Although it would have made more sense
to use <a class="xref" href="SetDataLabelColor.html" title="SetDataLabelColor"><span class="refentrytitle">SetDataLabelColor</span></a> to set the color for pie chart data
labels when that function was introduced, it would have not have been
backward compatible, since the default color comes from a different source.
