Here is a way to produce several histograms side by side as given in the attached image.
% preparing sample dataset
data{1} = rand(1, 1000);
data{2} = 3*rand(1, 1200);
data{3} = 2*rand(1, 800);
data{4} = 5*rand(1, 500);
data{5} = 4*rand(1, 1000);
h = histogram(data{1});
hold on
for i = 2:length(data)
[~,edges] = histcounts(data{i})
h = histogram(data{i} + h.BinEdges(end), h.BinEdges(end) + edges)
end
