If you have Matlab 2014b or 2015a, you can use histogram and specify 'facealpha' to make the bars semitransparent. If you have an older version of Matlab, use histf.

Just compare the counts to see if the histograms are different.
[counts1, grayLevels1] = imhist(image1(:,:,1)); % Red channel of image 1
[counts2, grayLevels2] = imhist(image2(:,:,1)); % Red channel of image 2
sameHist = all(counts1 == counts2);
Do it for all the other color channels too. Note well that having the same histogram does NOT mean the images will look the same . Not by a long shot as simple thought experiments will reveal to you. I mean you could just scramble around the pixels and get a totally different looking image that has the identical histogram.
