Hi,

I want to show the cumulative value of y in the stacked bar using the given data value provide. Could anyone please give me a hint for this? Thank you.

The positions of the text should be in a row or column vector. Hence reshape it and will work.

While for the y-position of the text, you may adjust the margin to put the text in the required position. I use 0.06 in the following example.

Of course, you may also modify the fontsize or font color if needed.

d7 = [0.1 0.2 0.15 0.2];

d1= [0.3 0.2 0.15 0.15];

d2= [0.2 0.15 0.15 0.15];

d3= [0.1 0.15 0.1 0.15];

d4= [0.1 0.1 0.2 0.15];

d5= [0.1 0.1 0.05 0.15];

d6= [0.1 0.1 0.2 0.05];

aor= [22.469 21.973 19.7 16.278];

diameter = [0.3 0.2 0.1 0.1 0.1 0.1 0.1; 0.2 0.15 0.15 0.1 0.1 0.1 0.2; 0.15 0.15 0.1 0.2 0.05 0.2 0.15; 0.15 0.15 0.15 0.15 0.15 0.05 0.2];

b = bar(aor,diameter, 'stacked');

xtickformat('%.2f')

grid on

xpos=reshape(repmat(aor,size(diameter,2),1),[],1); % Make it to a column vector

ypos=reshape(cumsum(diameter'),[],1); % Make it to a column vector

text(xpos, ypos+0.06,arrayfun(@(x) sprintf('%0.2f',x),ypos,'uni',0),'HorizontalAlignment','center','VerticalAlignment','top','FontWeight','bold','FontSize',12)

axis([14 24 0 1.2]);
