Hi,

I have 12 histograms, and each of them has different maximum number of counts, I want the ylim of all figures to be unified, i.e. ylim to be highest value of counts for all 12 histograms. That is represented in MaxH in the code below:

Max = ceil(max(totalPowerdB(:)))+1;
SS  = unique(sort(totalPowerdB(:)));
Min = floor(SS(2))-1;
nbins  = 20;
count  = 0;
MaxH   = 0;
for jj = 1:iRegion  
    for ii = 1:1
        count = count+1;
        if totalPowerdB(jj,:,ii)~=-inf
        figure(count)
        end
        txt = ['Region ',num2str(jj),' Reciever ',num2str(ii)];
        H = histogram(totalPowerdB(jj,:,ii),nbins,'FaceColor',rand(1,3));       
        if max(H.Values) > MaxH
            MaxH = max(H.Values);
        end
        hold on; grid on;
        legend(txt);
        title('Received Power Histogram')
        xlim([Min Max]);
        xlabel('Power Level [dB]');
        ylabel('Counts');
    end
end

I can’t run your code (no data), so I simulated it.

This seems to work:

for k = 1:12
    figure(k)
    H = histogram(rand(20), 20, 'FaceColor',rand(1,3));
    HAx{k} = H.Parent;                                          % Get & Save Axes Handles
    maxH(k) = max(H.Values);
end
ylim([HAx{:}], [0 max(maxH)])
