<P>
If <CODE><a href="../Characteristics/GraphLegend/legend.htm">LEGENDON</a></CODE> is set true, i.e.,
non-zero, a legend entry is drawn into a legend frame box. A legend entry consists of a short line
segment, with or without plotting symbol(s), and a string. The legend entry is drawn when the
<CODE>GRAPH</CODE> command is entered. The string portion of the legend entry is expected as the
first parameter of the <CODE>GRAPH</CODE> command. For example:</P>
<p>
<font color="blue"><PRE>
GRAPH 'legend entry' X Y
</pre></font></p>
<P>
If <CODE>LEGENDON</CODE> is false, i.e., zero, a string entered as a first
parameter with the <CODE>GRAPH</CODE> command will be ignored.</p>
