text to stack bar

Hello ,

I am thinking of adding text to stack bar but its not working can someone suggest improvement in code . where i am going wrong. Thanks in advance like each value should be in that mark only eg :- 1051 in red , 1427 in blue mark & 1580 in red mark

clear all
close all
clc
x=input('Enter the first column:','s')
r=xlsread('Master_data.xlsx',strcat(x,':E',num2str((str2num(x(2:strlength(x)))+8))))
i=1
C(1,:)=[r(i+1) r(i+10) r(i+19) r(i+28) r(i+2) r(i+11) r(i+20) r(i+29)]
C(2,:)=[r(i+4) r(i+13) r(i+22) r(i+31) r(i+5) r(i+14) r(i+23) r(i+32)]
C(3,:)=[r(i+7) r(i+16) r(i+25) r(i+34) r(i+8) r(i+17) r(i+26) r(i+35)]
D(1,:)=C(1,:)
D(2,:)=C(2,:) -(C(1,:))
D(3,:)=C(3,:)-(C(2,:))
D=D'
h=figure
hB=bar(D,'stacked')
set(hB(1),'Facecolor','red')
set(hB(2),'Facecolor','blue')
set(hB(3),'Facecolor','green')
legend('10 sec','25 sec', '60 sec')
xt = get(gca, 'XTick');
set(gca, 'XTick', xt, 'XTickLabel', {'C1-Case1' 'C1-Case2' 'C1-Case3' 'C1-Case4' 'C2-Case1' 'C2-Case2' 'C2-Case3' 'C2-Case4'},'fontsize',12)
title('Cumulative CO emission[mg] ','fontsize',12);
ylabel('Cumulative CO emission[mg]','FontSize',12)
labels_stacked=num2str(C(:,1),'%.1f ');
hText = text(1:size(C), C(:,1), labels_stacked);
set(hText, 'VerticalAlignment','top', 'HorizontalAlignment', 'center','FontSize',12, 'Color','k');

hi

the y coordinates of the text ( = C(:,1) in your code) is not correct if you want the text to appear below the top of each color zone (or in the middle)

all the best
