Displaying histogram in ImageJ with fixed limits

I am trying to view a 16 bit image with min intensity value of 0 and max
intensity value of 32767.
When the image is displayed the max values "look" white however, for a 16
bit image it should be a shade of gray.
As I move the cursor over the image the correct intensity value is displayed
in the ImageJ window (that is x coordinate, y coordinate , value).
If I adjust the brightness and contrast and manually set min = 0 and max
= 32767 the display of the image is corrected so that the max intensity
values look to be a shade of gray.  Although the display is changed, the
histogram still shows min=0 and max = 32767. How do I get the histogram to
display fixed limits (0 to 65535) for 16 bit image even though the image
only contains two values zero and 32767?

I am able to force it to show the entire range (0 to 65535) by strategically
setting a single pixel value to 65535. When this is done the entire range is
displayed automatically, but I would like for the entire range to be
displayed in the histogram automatically without the need to tweak the image
to do so.

Does anyone know of a way to do this?

Thanks,
