MATLAB: Labels to a stacked bar

labelsstacked

I am trying to add labels for a stacked bar and need to help. I managed to add label to each part of the stack but unable to add at the total level (circled in red).

Here's a demo. 
% Create stacked bar plot
x = randi(3,20,5); 
h = bar(x,'stacked'); 
% Get the (x,y) coordinates for the top of each bar stack
y = sum(reshape(cell2mat(get(h', 'YData')),size(h,2),[]),1); 
x = unique(cell2mat(get(h', 'XData')),'stable')
% Define labels
labels = num2cell(char(((1:size(x,1))+64)'))';  % 'A' 'B' 'C' ... 
% Plot the text labels
offset = range(ylim)*.01; 
th = text(x,y+offset,labels,'HorizontalAlignment','left',...
        'VerticalAlignment','middle','rotation',90)
If you don't want to rotate the text labels, 
th = text(x,y,string(y'),'HorizontalAlignment','Center',...
        'VerticalAlignment','bottom');
For bar plots that are stacked and grouped, see this answer.
