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.
