Contour legend

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.
