Using "hold on" - bars do not have the same width

Hi
I seem to have the strange problem that when I plot the following, the bars of the two histograms do not seem to have the same width:
hold on
[N,X] = hist(feature_1(:,1:5))
Bh = bar(X,N,'facecolor',[0.7 0.2 0.2]);
[A,Y] = hist(feature_2(:,1:5))
Bh = bar(Y,A,'facecolor',[0.3 0.6 0.2]);
hold off
Why is that? I have attached the feature_1, feature_2 files. Thanks

Each call to the hist function is going to algorithmically choose the range and bin width, based on the data. You can specify the bins instead:
hist(feature_1(:,1:5),-10:2:15)
