Labels above bar-plot

Hello,

I have a matrix A (1X40). For this matrix I make its bar-plot. Aslo, I have the matrix B (1X40) which contains values, which I want to put as an label above each bar. I wrote a small code, but the values in matrix B do not appear (such label) above each bar. Below is the code.

bar(A) % 1X40
labels = arrayfun(@(value) num2str(values,'0.0f'),B,'UniformOutput',false);
text(A,B,labels,HorizontalAlignment','center',VerticalAlignment','bottom')

Your help is important !!!

Hi. Up to my understanding, the problem seems to be that when you use bar(A) the coordinates along x are 1, 2, ... 40. Assuming that variables A, B, and labels are correctly defined you could try this:

text(1:40, A, labels, 'HorizontalAlignment', 'center', 'VerticalAlignment', 'bottom');

For instance:

A = rand(1,40); B = rand(1,40);
labels = arrayfun(@(value) num2str(value,'%0.0f'),B,'UniformOutput',false);
bar(A);
text(1:40, A, labels, 'HorizontalAlignment', 'center', 'VerticalAlignment', 'bottom');

please expand the plot for a clear view.

A=1:5:200;
B=1:40;
bar(B)
text(1:length(A),B,num2str(B'),'VerticalAlignment','bottom','HorizontalAlignment','center'); 
box off

A = 1:10;
B = randn(1, 10)*10;

bar(A, B, 0.5);

labels = compose('%.0f', B);

labels = 1×10 cell array
    {'9'}    {'8'}    {'-3'}    {'-7'}    {'12'}    {'-31'}    {'-2'}    {'9'}    {'-8'}    {'-11'}

text(A, B, labels, 'HorizontalAlignment','center','VerticalAlignment','bottom')
