By default, the contours are labeled with the actual contour level. If
\-AXES
is used, then no legend is allowed.
If the \LEGEND
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.
Legend size
The size of the legend characters is LEGENDSIZE
.
The value of LEGENDSIZE
,
or %LEGENDSIZE
, can be changed with the
SET
command. The default value is %LEGENDSIZE =
3
Axis relocation
The legend requires the right end of the x-axis to be set to
75%
of the window, that is, %XUPPERAXIS
is
set to 75
.
By default, %XUPPERAXIS
is reset to
its former value after the CONTOUR
command is finished. If the \-RESET
qualifier is used, the axis location will not be reset.
