Change scale of intensity histogram

I'm trying to build an intensity histogram of one of my images (type uint16), but the scale it uses makes it impossible to select an area on it. (see image below)

Can anybody explain me how to change the scale for my intensity histogram, at the moment i use imhist to generate a histogram.

    % s = size(MRIbrain);
Slicenumber = round((s(3)/2));
A = MRIbrain(:,:,Slicenumber);
figure, imhist(A)
  end

Maybe you want :

ylim([min_value max_value])
