Hi everyone,

I would like to do a bar plot where each bar has a different label, but labels must be different than values contained in "y" vector, because I want to show on the top of each bar the percentage difference than the bar called "25% C_ax".

The values that I would like to show are shown in vector "z" (commented).

I tried to use the code below, but it did not work.

Does anyone could help me?

Thank you very much

clear all
close all
clc
x = categorical({'Rotor only','200% C_{ax}','100% C_{ax}','50% C_{ax}','25% C_{ax}'});
x = reordercats(x,{'Rotor only','200% C_{ax}','100% C_{ax}','50% C_{ax}','25% C_{ax}'});
y = [4.521,1.5605,1.4531,1.3533,1.3528]*(1e-5);
%y = [4.521,1.5605,1.4531,1.3533,1.3528]*(1e-5);
%z = [70.0774,13.3098,6.9025,0.0369,0];
hb = bar(x,y)
%text([1:length(y)], z, num2str(z),'HorizontalAlignment','center','VerticalAlignment','bottom')
numbersToAdd = [70.0774,13.3098,6.9025,0.0369,0];
barWidth = hb.BarWidth;
numCol = size(M,2);
cnt = 0;
for ii = numbersToAdd'
    cnt = cnt + 1;
    xPos = linspace(cnt - barWidth/2, cnt + barWidth / 2, numCol+1);
    idx = 1;
    for jj = xPos(1:end-1)
        val = numbersToAdd(cnt,idx);
        y = M(cnt,idx);
        text(jj, y + 1, num2str(val));
        idx = idx +1;
    end     
end
box on

ylabel("Work on the blade, J")
