MATLAB: Bar graph comparison with custom x-axis and text

figureimage processingmathematicssignal processingstatistics

Hi All,
I want to compare two vectors using bar graph with custom labels and a text on top of each bar. Can you please help me with this? Below is the code i tried:
y1=[[0.41 0.38 0.42]];
y2=[[0.63 0.75 0.81]];
x=1:3;
figure(1)
bar(x,[y1' y2'])
label1={'front1';'front2';'front3'};%%corresponds to y1
label2={'back1';'back2';'back3'};%%corresponds to y2
So basically, i want label1 and label2 in the x-axis and corresponding values of y1,y2 on top of the bar.

This will work for your two-variable problem:
y1=[[0.41 0.38 0.42]];
y2=[[0.63 0.75 0.81]];
x=1:3;
figure(1)
bar(x,[y1' y2'])
label1={'front1';'front2';'front3'};%%corresponds to y1
label2={'back1';'back2';'back3'};%%corresponds to y2
text(x, y1, label1, 'VerticalAlignment','bottom', 'HorizontalAlignment','right')
text(x, y2, label2, 'VerticalAlignment','bottom', 'HorizontalAlignment','left')
A more general approach:
labels = {label1; label2};
figure(1)
hBar = bar(x,[y1' y2']);
for k1 = 1:size(hBar,2)
    ctr(k1,:) = bsxfun(@plus, hBar(1).XData, [hBar(k1).XOffset]');
    ydt(k1,:) = hBar(k1).YData;
    text(ctr(k1,:),ydt(k1,:), labels{k1}, 'HorizontalAlignment','center', 'VerticalAlignment','bottom')
end
