MATLAB: Plot 2 vectors (different size) on same histogram normalized such that both have total area 1

ok so i have vector A and vector B

and i want to plot them both in histogram – with normalization probabillity for each,

this is a code i tried: i have [A] vector and [B] (different sizes)

figure(1)

histogram(A,100, 'Normalization','probability')

hold on

histogram(B,100, 'Normalization','probability');

ylabel('Probabillity'); xlabel('V');

But somhow they dont get same area under the histograms plots:

or it seems like this – maybe since one vector is more "dense" (longer) how to fix it so it will look the same area below (to be equal 1 surely)

Best,

Lital
