<TITLE>Contour legend</TITLE>
</HEAD>
<BODY BGCOLOR="#FFFFFF" TEXT="#000000">
<P><font size="+2" color="green">Legend</font></P>
<P>
By default, the contours are labeled with the actual contour level, using
three significant digits. If <CODE>\-AXES</CODE> is used, then no legend is allowed.</P>
<P>
If the <CODE>\LEGEND</CODE> qualifier is used,
then the contours are labeled with an integer index and the list of indices
corresponding to the actual contour levels, the legend, is plotted along
the right side of the axes. If areas and/or volumes are requested, using
<CODE>\AREAS</CODE> and/or <CODE>\VOLUMES</CODE>, these values will also appear in the legend.</P>
<P>
If you zoom in on a contour plot, by setting the axis scales beforehand,
and you use the <code>\PARTIAL</code> qualifier as well as the <code>\AREAS</code> qualifier,
then the areas will be percentages of the area currently showing on the
graph. By default, the areas are percentages of the total area.</P>
<P>
To add more contours to a contour plot, re-issue the same contour command
with the <CODE>\CONTINUE</CODE> qualifier and
the legend will be continued from where it left off. You must have used the
<CODE>\-RESET</CODE> qualifier on the previous <CODE>CONTOUR</CODE> command if you intend to
use <CODE>\CONTINUE</CODE> on a succeeding <CODE>CONTOUR</CODE> command.</P>
<P>
<font size="+1" color="green">Legend size</font></P>
<P>
The size of the legend characters is controlled with the
<CODE><a href="../Characteristics/GeneralGraph/legendsize.htm">LEGENDSIZE</a></CODE>
characteristic. The default value of <CODE>%LEGENDSIZE = 3</CODE>.</p>
<P>
<font size="+1" color="green">Axis relocation</font></P>
<P>
The legend requires the right end of the <i>x</i>-axis to be set to
<CODE>75%</CODE> of the window, that is,
<CODE><a href="../Characteristics/Xaxis/xupperaxis.htm">%XUPPERAXIS</a></CODE> is set to <CODE>75</CODE>.</P>
<P>
By default, <CODE>%XUPPERAXIS</CODE> is reset to its former value after the
<CODE>CONTOUR</CODE> command is finished. If the <CODE>\-RESET</CODE>
qualifier is used, the axis location will not be reset.</P>
