How can I plot the column-wise frequency of different elements for an mxn array?

Hello, I have an mxn array of numbers (integers or decimal numbers). I can use hist function separately for each column to find out frequency of each elements, for example: hist on each column gives output like 10 1's, 15 2's 25 7's in column 1; 25 2's, 25 3's in column 2; etc. Now I want to plot the histograms in a 3D plot, so that x axis = m, y axis = n, z axis = frequency of each element.

It seems very plain and simple, but somehow I am really struggling with this. Any help is greatly appreciated. Thanks for your time.

I wanted to ask a question and confused it with the newsgroup messaging, so I posted a message in the newsgroup. Was wondering if it is illegal to ask the same question in the Newsgroup and MATLAB Answers.

I would use histc (or histcounts) and plot the results with bar3:

M = randi(3, 15, 6);                                % Create Data
binrng = 0:4;                                       % Set Bin Ranges
counts = histc(M, binrng);                          % Histogram Counts

figure(1)
bar3(binrng, counts)                                % Plot
xlabel('Columns')
ylabel('Rows')
zlabel('Frequency')

Thank you! Thank you! Thank you! I only changed binrng = 1:3 instead of 0:4 for your example, and that gave me what I want. Thank you soooo much!
