		NTCONTOUR COLON COMMANDS

The colon commands take one argument and may be abbreviated.

:dscale	    [string]	Select log/linear plot scale for density 
:imin	    [real]	Set the minimum intensity plot limit
:imax	    [real]	Set the maximum intensity plot limit
:iscale	    [string]	Select log/linear plot scale for intensity 
:interval   [real]	Set the interval between contours
