How to put a numerical value inside a Bar graph?

Hi!

I'd like to know how can I set the values inside the bar plot, just like this:

I obtain the following bar plot using the code above but I can't place values in the correct center position.

b = bar(X,Y);
hold on
b.FaceColor = 'flat';
b.CData(1,:) = [0 0.447 0.741];   % color editing
b.CData(2,:) = [0.850 0.325 0.098];
b.CData(3,:) = [0.466 0.674 0.188];
b.FaceAlpha = .7;      % opacity
text(1:length(Y),Y,num2str(Y'),'vert','bottom','horiz','center');  % values position
std = [2.1 4.4 6]; % standard deviation
er = errorbar(X,Y,std);    
er.Color = [0 0 0];                            
er.LineStyle = 'none';  
set(gca, 'ytick', []);
box off

Can you help me, please?

Thank you,

Sara

Read about text, annotation.

Change the text call to:

text(1:length(Y),Y/2,num2str(Y'),'vert','bottom','horiz','center');  % values position

That should work, if I understand correctly what you want to do.

Yes, perfect it works. Thank you!

Another question: how can I print also '%' after the numbers?

I undersood that num2str(Y') print the number but I can't insert the percentage.

As always, my pleasure!

There are a few different ways to add the ‘%’:

text(1:length(Y),Y/2,[num2str(Y') ['%';'%';'%']],'vert','bottom','horiz','center');  % values position

text(1:length(Y),Y/2,sprintfc('%g%%',Y),'vert','bottom','horiz','center');  % values position

text(1:length(Y),Y/2,compose('%g%%',Y),'vert','bottom','horiz','center');  % values position

The first concatenates the ‘['%';'%';'%']’ vector to the num2str vector, the second and third use different functions to create a cell array of strings that prints the value with the ‘%’. Since the ‘%’ is a valid cointrol character to those functions, to print one ‘%’ it is necessary to use '%%', (The same is true for other control characters in these and similar functions.)
