<code class="function">SetLegendBgColor</code> sets the background color used in the
legend.
    </p></div><div class="refsect1"><a id="idp1378230684"></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="idp1378232540"></a><h2>Notes</h2><p>
If <code class="function">SetLegendBgColor</code> is not used, the legend background
color will be the same as the image background color.
The image background color is set with <a class="xref" href="SetBackgroundColor.html" title="SetBackgroundColor"><span class="refentrytitle">SetBackgroundColor</span></a>,
and defaults to white.
    </p><p>
If you position the legend outside the plot area, this function is useful to
make it stand out more, by using a color that differs from image background
color. Similarly, if your legend is positioned inside the plot area, but you
have not changed the plot area background, you can use this function to make
the legend stand out with a different background color.
    </p></div><div class="refsect1"><a id="idp1378234588"></a><h2>History</h2><p>
This function was added in PHPlot-6.0.0. In earlier releases, the legend
background was always drawn using the image background color.
