Legend

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.
