<code class="function">SetLegendWorld</code> lets you position the legend on the
image, using world coordinates, rather than letting PHPlot position it for you.
(World coordinates are the coordinate space of your data points.)
    </p></div><div class="refsect1"><a id="idp1378340748"></a><h2>Parameters</h2><div class="variablelist"><dl class="variablelist"><dt><span class="term"><em class="replaceable"><code>$x</code></em>, </span><span class="term"><em class="replaceable"><code>$y</code></em></span></dt><dd><p>
World coordinates of the upper left corner of the legend box.
The units and origin are the same as the data you are plotting.
          </p></dd></dl></div></div><div class="refsect1"><a id="idp1378342572"></a><h2>Notes</h2><p>
The default behavior is for PHPlot to position the legend in the
upper right corner of the plot area.
    </p><p>
See <a class="xref" href="SetLegendPosition.html" title="SetLegendPosition"><span class="refentrytitle">SetLegendPosition</span></a> for more flexible legend
positioning options.
<code class="literal">SetLegendWorld($x, $y)</code> is equivalent to
<code class="literal">SetLegendPosition(0, 0, 'world', $x, $y)</code>.
This places the top left corner of the legend at world coordinates $x, $y
with no pixel offset.
    </p><p>
See also <a class="xref" href="SetLegendPixels.html" title="SetLegendPixels"><span class="refentrytitle">SetLegendPixels</span></a>.
    </p><p>
This function will not work with pie charts, because they have no valid
world coordinates.
    </p></div><div class="refsect1"><a id="idp1378345628"></a><h2>History</h2><p>
This function did actually work with pie charts through PHPlot-5.5.0,
although we are not sure what it did, since pie charts do not have valid
world coordinates.
    </p><p>
Through PHPlot-5.0rc3, it was required that the
data array, axis types, and any other setting which affects the scale of
the data be set up before this function is used.
Starting at PHPlot-5.0.4 this is no longer required, as the coordinates
you supply are not scaled until the plot is drawn.
