Hi This actually works to some extent but the problem is i got all the values for each bar shown on top. So for each bar all the Y values are being shown.
x=[1:2:23]';
y=abs([121 41 20.6 12.5 8.1 5.8 4.4 3.5 3 2.7 2.3 2.1]);
bar(x,y)
text(x,y,num2str(y,'%0.2f'),...
'HorizontalAlignment','center',...
'VerticalAlignment','bottom')
Please tell me what is wrong! Thanks!

Hi gabe, Can you please help me with displaying the value on top of bar plot.I am using GUI and my 7 different coloured bars are continuously changing with analog input so the value should also change continuously on top. I would really apreciate your answer.

num2str(y,'%0.2f')
converts the numbers in y, into one long string, and therefor it's repeated above each bar.
you need to have a seperate string for each value. The easiest fix here woul be:
num2str(y','%0.2f')

x=[1:2:23]';
y=abs([121 41 20.6 12.5 8.1 5.8 4.4 3.5 3 2.7 2.3 2.1]);
bar(x,y)
for i1=1:numel(y)
text(x(i1),y(i1),num2str(y(i1),'%0.2f'),...
'HorizontalAlignment','center',...

What if I don't have an X axis data, I have data to be plotted on just the Y axes. Then?
Something like this -
Y=[198 138 172 188 190 192];
bar(Y);
Then?

Try generating an arbitrary x array of length equal to y. Omit the x array in your plot using the gca handle as shown below:
Y=[198 138 172 188 190 192];
% arbitrary array
X = 1:6;
figure
bar(X,Y);
labels = arrayfun(@(value) num2str(value,'%2.2f'),Y,'UniformOutput',false);
text(X,Y,labels,'HorizontalAlignment','center','VerticalAlignment','bottom')
% clears X axis data
set(gca,'XTick',[]);

I've written a function to do just this. It's called barvalues, and is very easy yo use.
simply:
bar(x);
barvalues;

Can be a little cleaner than the above solutions, by making a cell array with the labels in advance using the arrayfun function.
x=[1:2:23]';
y=abs([121 41 20.6 12.5 8.1 5.8 4.4 3.5 3 2.7 2.3 2.1]);
bar(x,y)
labels = arrayfun(@(value) num2str(value,'%2.1f'),y,'UniformOutput',false);
text(x,y,labels,...
'HorizontalAlignment','center',...
'VerticalAlignment','bottom')

Please Try this code, Hope your problem will be solved. Best of luck
clc
clear all
close all
x = [1 2 3 4 5 6 7 8 9 10];
y = [200 250 300 350 400 450 500 550 600 700 ];
z= bar(x,y)
for i1=1:numel(y)
text(x(i1),y(i1),num2str(y(i1),'%0.0f'),...
'HorizontalAlignment','center',...
'VerticalAlignment','bottom')
end
% text(1,43,'42','Color','k','FontSize',9)
% plot(x,y, '->','LineWidth',2)
xlabel('Friends')
ylabel(' Record')
title('Friends List')
grid on
ax=gca;
ax.XTick = [1 2 3 4 5 6 7 8 9 10 ];
ax.XTickLabels = {'Junaid', ' Qadir' ,' Sahar ',' Ubaid ',' Munsif ',' Yousaf ',' Sami ','Najm',' Shakir', ' Pakistan'};
ax.XTickLabelRotation = 45;
z.FaceColor = 'flat';
% z.EdgeColor= '[1,0,0]';
z.CData(1,:) = [1,1,0];
z.CData(2,:) = [1,1,0];
z.CData(3,:) = [1,1,0];
z.CData(4,:) = [1,1,0];
z.CData(5,:) = [1,1,0];
z.CData(6,:) = [1,1,0];
z.CData(7,:) = [1,1,0];
z.CData(8,:) = [1,1,0];
z.CData(9,:) = [1,1,0];

Please try with this code

Hi guys,
But despite I have tried to put the avlues on the TOP/OVER every one bar, I could not, even in the code I already change botton for cap, but it has been unsuccesfull.
Could you help me to set the values on the peak of every one bar?.
The code is attached.
Thanks
