This command controls the appearance of two dimensional plots. The data set is again specified by <ik>, the allowed values for <p> are:
1 : contour map 2 : bitmap 3 : contour map & bitmap
The z-range of the values to be converted to the colour range of the bitmap is determined by the setting of the first contour line range (see command hlin). The colourmap is defined by the 'cmap' command.
