Hi, i have two histograms of X and Y and what i would like to do this if it is possible :
i would like to display an histogram which will be the quotient of the two histograms. Of course i have the same borders for the two sides.
Any idea ?
Thanks a lot !

If you are using the newer histogram function, then access the Values properties of the two, calculate the ratios, and use bar() to draw the result.

subplot(1,3,1);
h1 = histogram(rand(1,100).^2, 15);
h1_edges = h1.BinEdges;
h1_cents = mean([h1_edges(1:end-1); h1_edges(2:end)]);
subplot(1,3,2);
h2 = histogram(randn(1,100).^2, 15);
ratio = h1.Values ./ h2.Values;
subplot(1,3,3);
bar(h1_cents, ratio);
Make sure they have the same number of bins.
Also, the above is not a great example because the range of the second histogram is wider, so the bins do not align. Or perhaps it is a good example, as it shows the danger of just taking the ratio of the bins instead of making sure that the bins are for the same range.
