Hi Olivier,

Octave's stacked option appears to work differently than Excel.  I prefer Octave's behavior (although it would be considered a bug

if it differs from MATLAB, I don't have MATLAB to check).   It appears that you can get the plot you want by plotting the positive 

and negative values separately:

z=[1 -2 3;  4 3 1]
zt = z;
zt(zt<0) = 0
h = bar (zt, 'stacked');
hold on
zt = z;
zt(zt>0) = 0
h = bar (zt, 'stacked');
hold off

FYI.  Octave's behavior is consistent with MATLAB's,

only for your code.  his original code does produce different results in Matlab and Octave. 

Apparently this was a change introduced in MATLAB 2019b, quoting from the release notes:

"Stacked groups of bars display negative bars below zero, rather than overlapping the bars."
