Auto adjust y axis with imhist

Hello, I'm having problem with autoscale of y axis when plotting histogram of an image intensities.

for example, the following code:

img = imread('cameraman.tif');
subplot(2,3,1)
image(img)

colormap('gray')
subplot(2,3,2)
imhist(img);

produces the output like shown in the attached picture.

A you can see, the values go beyound the upper limit on the plot.
