How do I add the numbers on top of the bar graph?

file = input("Please enter the name of the data file : ",'s');
[num,txt,raw] = xlsread(file);
amino_names = txt(3:end,1);            
atomic_weights = [15.994; 12.01; 14; 32.065; 1.01];
amino_weights = num * atomic_weights;
amino_weights = round(amino_weights,2);             
disp("**** The report is ready ****");
T = table(amino_names,amino_weights);
T.Properties.VariableNames = {'Amino Acid','Molecular Weight'};   
disp(T)                                                             
bar(amino_weights)
ylabel("Molecular Weights")
title("Molecular weights for different amino acids")
xticks(1:length(amino_names))  
xticklabels(amino_names)   
xtickangle(90)

Answer 1

A = rand(3,1) ;
h = bar(A) ;
text(h.XData,h.YData+0.05,num2str(A)) ;

What are the h.XData, h.YData+0.05?

[KSSV]

REad about text, it needs positions (x,y) to place the text you want. h.XData, h.YData are those positions which can be obtained from the plot. You can try it yourself.

%I replaced xticks(1:length(amino_names)) with:
text(1:length(amino_names),amino_weights,num2str(amino_weights, '%0.2f'),'HorizontalAlignment','center','VerticalAlignment','bottom');
