Display values in bar plot (app designer)

I have a problem with the code,

Why do I not see values ​​in a graph like in Figure

Notice the yellow in the picture

X = categorical({'Small','Medium','Large'});

X = reordercats(X,{'Small','Medium','Large'});

Y = [2 3 6];

bar(X,Y);

b = bar(app.UIAxes,X,Y);

for i=1:1:length(X)

text(i:i,Y(i)',num2str(Y(i)','%0.2f'),'HorizontalAlignment','center','VerticalAlignment','bottom')

box off

end

Pass app.UIAxes as first argument of text()

text(app.UIAxes, i:i, Y(i)', num2str(Y(i)','%0.2f'),'HorizontalAlignment','center','VerticalAlignment','bottom')

THIS IS WORK TNXX!!!!

but do you know way the figure pop up?

i fix my code to this :

X = categorical({'Small','Medium','Large'});

X = reordercats(X,{'Small','Medium','Large'});

Y = [2 3 6];

bar(app.UIAxes,X,Y);

for i=1:1:length(X)

text(app.UIAxes, i:i, Y(i)', num2str(Y(i)','%0.2f'),'HorizontalAlignment','center','VerticalAlignment','bottom')

box off

end

In app designer, pass the handle of the UIAxes object to all graphical functions. Otherwise a window will pop-up

box(app.UIAxes, "off")

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

Sara,

You are more likely to get an answer if you post a new question to MATLAB Answers, rather than add to an existing question.

As long as you are not using a stacked bar plot, I think all you need to do in your case is divide Y by two and switch the vertical alignment from bottom to middle.

text(1:length(Y),Y/2,num2str(Y'),'vert','middle','horiz','center');
