MATLAB: How I can calculate average of some histograms

Question

would you please guide me how I can calculate average of some histograms and then show it on the same histogram? thanks

Answer 1

If the counts are stored in counts1, counts2, counts3, counts4, counts5, and the bin centers or bin edges were fixed (not just the number of bins), then

mean_counts = mean([counts1(:), counts2(:), counts3(:), counts4(:), counts5(:)], 2);

If necessary, calculate the bin centers into bin_centers from the bin edges:

bin_centers = (bin_edges(1:end-1) + bin_edges(2:end)) / 2;

Then to add to the plot in the current axes,

hold on
relative_width = 1;
bar(bin_centers, mean_counts, relative_width);
