CNTR has been kept deliberately simpler than other display tasks - so it 
does not have this option.  You will need to "move up" in the world - 
e.g. KNTR.  The adverb CBPLOT then controls which corner is used and how 
much the beam contour is filled in.  KNTR has a better algorithm for 
drawing the contours as well.  It has many other options - grey-scale 
images, color, polarization lines, multiple panels, etc.  These can be 
ignored pretty much for simple cases and then explored for making more 
interesting displays.
