<BODY BGCOLOR="#FFFFFF" TEXT="#000000">
<P><font size="+2" color="green">Plot data only</font></P>
<P>
The <CODE>GRAPH\OVERLAY</CODE> command plots the data, but does not draw axes. Autoscaling will not
apply. The <CODE>GRAPH\OVERLAY</CODE> command overlays on an existing set of axes. For example:</P>
<p>
<font color="blue"><PRE>
GRAPH\OVERLAY X Y ! overlay data curve on current axes
GRAPH\HIST\OVER X Y ! overlay histogram on current axes
</PRE></font>
<P>
If <a href="../Characteristics/GraphLegend/legend.htm"><CODE>LEGENDON</CODE></a> is
true, i.e., non-zero, then the data variables are not necessary. That is, you can enter:</P>
<p>
<font color="blue"><pre>
GRAPH\OVERLAY 'legendentry'
</pre></font>
<P>
and an entry will be made to the legend, but no curves are plotted. The plotting symbol, as set by
the <a href="../Characteristics/PlottingSymbol/plotsymbol.htm"><CODE>PLOTSYMBOL</CODE></a> characteristic,
will be used in the legend.</P>
