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

Answer 1

Pass app.UIAxes as first argument of text()

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

Thank you! @Ameer Hamza

I am glad to be of help!

Answer 3

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');

%Greeting

% I encountered an issue with values displayed above the bar. To enhance accuracy, I need to reduce the font size.

% The applying code as follow

q = [0.3 0.35 0.4 0.28 0.6];

kl = 256; % key length

sm = 25; % number of simulation run

g = zeros(1,sm); % Initiallize the sum to zero

g2 = zeros(1,sm); % Initiallize the sum to zero

z = zeros(1,sm); % Initiallize the sum to zero

figure;

v1=0;

v2=0;

for j =1:sm

N = randi([1 5],1);

y = 0;

y2 = 0;

for k = 1:N

y = y+ q(k)*kl; % computing the sum

end

y2 = N * kl;

g(j) = y;

g2(j) = y2;

%z(j) = [y y2];

v1 = v1 + y;

v2 = v2 + y2;

end

hold on;

xx = 1:sm;

%g= sort(g);

%g2= sort(g2);

%z = [g, g2];

%bar(g2,0.6);

%hold on;

%bar(g,0.4);

subplot(2,2,1);

bar(xx-0.25,g2,0.4,'red');

hold on;

bar(xx+0.25,g,0.4,'blue');

axis([0 26 0 1300])

title('Sample 1');

xlabel('Simulation Number');

ylabel('Total Generated Keys (bits)');

legend('Without SDQTRF', 'With SDQTRF');

text(1:length(g2),g2,num2str(g2'),'vert','bottom','horiz','center');

text(1:length(g),g,num2str(g'),'vert','bottom','horiz','center');
