How to plot stacked bar in Matlab with showing each limit ?

>> Y = [5 1 2; 8 3 7; 9 6 8; 5 5 5; 4 2 3];  % sample data from bar example...
>> Z=cumsum(Y,2);                            % bar cumulative heights for positioning
>> X=repmat([1:5].',1,3);                    % x locations for each Y
>> bar(Y,'stack')                            % base stacked bar
>> colormap(copper)                          % change color map
>> arrayfun(@(x,y,z) text(x,y,num2str(z), ...
                         'horizontalalign','center', ...
                         'verticalalign','top', ...
                         'color','w'), ...
                          X,Z,Y)   % write the labels for each subset

Salt to suit colors, locations. Use average of the bar height plus lower to center vertically, for example. >>
