qualifiers

 Qualifiers: \SPECIFIC, \INTERPSIZE, \POLAR, \LEGEND, \COLOURS, \PARTIAL,
             \RESET, \BORDER, \AXES, \COORDINATES, \AREAS, \VOLUMES

defaults

 Defaults: x = [1;2;3;...], y = [1;2;3;...], \NOSPECIFIC, \NOINTERPSIZE,
           \NOPOLAR, \NOLEGEND, \NOCOLOURS, \RESET, \NOAREAS, \NOVOLUMES,
           \BORDER, \NOCOORDINATES, \AXES

BORDER

 By default, the border, or boundary, of the matrix is outlined within
 the axes.  If the \NOBORDER qualifier is used, this rectangular border
 is not drawn.

AREAS

 If the \AREAS qualifier is used, the area contained within each contour
 is calculated as a percentage of the total area.  The area percentages
 are stored in a vector named CAREA. The default is \-AREAS.

 If you zoom in on a contour plot, by setting the axis scales beforehand,
 and you use the \PARTIAL 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.

    • VOLUMES

     If the \VOLUMES qualifier is used, the volume contained within
 each contour is calculated as a percentage of the total volume.
 The volume percentages are stored in a vector named CVOLM.
 The default is \-VOLUMES.

 If you zoom in on a contour plot, by setting the axis scales beforehand,
 and you use the \PARTIAL qualifier, then the volumes will be percentages
 of the region currently showing on the graph.  By default, the volumes
 are percentages of the total volume.

    Additional Information on:

    • min_max_values

     The minimum and maximum x values for each contour are automatically
 stored in vectors named CXMIN and CXMAX; the minimum and maximum y
 value for each contour are automatically stored in vectors named
 CYMIN and CYMAX.  Each time the CONTOUR command is entered, these
 vectors are emptied and replaced, so if you wish to keep them, they
 should be copied into other vectors.
