I am using Bar plot for plotting the following code i am using

ABC=xlsread('ABC.xlsx'); 
figure(1);
for i= 0:3
    A= bar(ABC(:,i+1:i+3))
    set(gca,'XTicklabel',{'25','50','75','100'})
    xlabel('time')
    for j=1:3
        text(A(i),sprintf('(%.0f)',A(i)))
    end 
end

But I want the y data on it how can i proceed any hint i am using text command...Any changes in code can anyone suggest Thank you in advance ..Also i am using Matlab 2016b version

text(A(i),sprintf('(%.0f)',A(i))) - your syntax seems doesn't right. Please follow the following syntax to defined values of y on your bar plot.

text(x,y,'string','PropertyName',PropertyValue....).

I tested this code on 2014b. Though it can be easily done with later version.

close all;

x = [25 50 75];

vals = [6000 3000 3100;7000 3100 3200;7900 3100 3200];

b = bar(x,vals);

dx = [-5, 0 , 5];

for i = 1:length(x)

for j = 1:length(vals)

text(x(i)+dx(j),vals(i,j),num2str(vals(i,j),'%.0f'),...

'HorizontalAlignment','center',...

'VerticalAlignment','bottom')

end

Why not using the example in the documentation by getting the EndPoints as follows:

clear;
clc;
x = [25 50 75];
vals = [6000 3000 3100;7000 3100 3200;7900 3100 3200];
b = bar(x,vals);
dx = [-5, 0 , 5];
text(cat(2,b.XEndPoints),cat(2,b.YEndPoints),string(cat(2,b.YData)),'HorizontalAlignment','center',...
        'VerticalAlignment','bottom')
