Plot figures in the same figure (MATLAB)

Dear members,

I have this program for one matrix

H=[0 1 1 0 1 0 1 1 1 0;
   0 1 1 1 0 1 0 0 1 1;
   1 1 1 0 0 1 1 1 0 0;
   1 0 0 1 1 0 0 1 1 1;
   1 0 0 1 1 1 1 0 0 1];
dvi = sum(H,1);            
dci = sum(H,2)';
[adv,bdv] = hist(dvi,unique(dvi));
[adc,bdc] = hist(dci,unique(dci));
dv = sum((adv./sum(adv)).*bdv);
dc = sum((adc./sum(adc)).*bdc);
set(gca,'XTick',[]);        
set(gca,'YTick',[]);       
adv(adv == 0) = NaN;
stem(bdv,adv,'linewidth',2);
hold on;
adc(adc == 0) = NaN;
stem (bdc,adc, 'linewidth',2);
xlim([min(min(bdv),min(bdc))-1 max(max(bdv),max(bdc))+1]);
xlabel('Degree of nodes');
ylabel('Number of nodes');
grid on;
axis on;
legend('dv','dc','location','NorthEast');

I got this figure

In the case of adding another matrix and to plot the result of the two matrices in one figure, how can I do that please.

Add the second matrix to the code, concatenate it with ‘H’ along dimension 3, then use a for loop to address and plot them.

H1=[0 1 1 0 1 0 1 1 1 0;
    0 1 1 1 0 1 0 0 1 1;
    1 1 1 0 0 1 1 1 0 0;
    1 0 0 1 1 0 0 1 1 1;
    1 0 0 1 1 1 1 0 0 1];

H2 = randi([0 1], size(H1));                                        % Second Matrix
Hm = cat(3,H1,H2);                                                  % Concatenate To 3D Array

hold on
for k = 1:size(Hm,3)
    H = Hm(:,:,k);                                                  % Set 'H' To Correct Matrix
    dvi = sum(H,1);            
    dci = sum(H,2)';
    [adv,bdv] = hist(dvi,unique(dvi));
    [adc,bdc] = hist(dci,unique(dci));
    dv = sum((adv./sum(adv)).*bdv);
    dc = sum((adc./sum(adc)).*bdc);
    set(gca,'XTick',[]);        
    set(gca,'YTick',[]);       
    adv(adv == 0) = NaN;
    stem(bdv,adv,'linewidth',2);
%     hold on;
    adc(adc == 0) = NaN;
    stem (bdc,adc, 'linewidth',2);
    xlim([min(min(bdv),min(bdc))-1 max(max(bdv),max(bdc))+1]);
end
hold off
xlabel('Degree of nodes');
ylabel('Number of nodes');
grid on;
axis on;
legend('dv','dc','location','NorthEast');

This works with the matrices, however it does not appear to produce the result of the original code with the random matrix I created here to test the code. Since I am not certain what that is, I defer to you to solve that. It might be necessary to use 'DisplayName' to create the legend correctly.

@Star Strider Thank you so much.

Can you tell me please how to create the legend using "DisplayName". Because I want to name dv(blue),dc(red) for (H1) and dv(orange),dc(purple) for (H2)

[Star Strider]

As always, my pleasure!

It is difficult for me to understand what the posted code does, so this is a separate example that would be possible to adapt with the histogram calls —

red = [1 0 0];
blue = [0 0 1];
orange = [0.8500 0.3250 0.0980];
purple = [0.4940 0.1840 0.5560];
clrs = { blue red; orange purple};

figure
hold on
for k = 1:2
    x = [1 2]+2*(k-1);
    y = rand(1,2);
    bar(x(1), y(1), 0.1, 'FaceColor',clrs{k,1}, 'DisplayName',sprintf('dv H%d',k))
    bar(x(2), y(2), 0.1, 'FaceColor',clrs{k,2}, 'DisplayName',sprintf('dc H%d',k))
end
grid
hold off
legend('Location','best')

Thsi should get you started.
