Bar graph - plot data

Hello, I would like to plot a graph like this. Can anyone help me in writing this code?

Thank you so much

Refer to bar, there are plenty of examples as well.

There is no example how to write tau and sigma and submarks like 1, 2 , 3

[Dyuman Joshi]

Use xticklabels

Hello Francesco,

You can refer to this thread for more info, but this should do the trick

close all
data=[2,3;2,6;2,6;2,6];
ax=axes;
b=bar(data);
ylim([0 12])
L1 = ["Mu" "Tau"];


a3=[b(1).XEndPoints; b(2).XEndPoints];
x3=a3(:)';
yp1 = -0.5*ones(size(x3));
yp2 = 2.5*yp1;
ax.XTickLabel={''};

for i=1:2:numel(x3)
    text(x3(i)-0.08, yp1(i), L1(1))
    text(x3(i+1)-0.08, yp1(i), L1(2))
end
L2=['1' '2' '3' '4'];
for i=1:4
    text(i, yp2(i), L2(i))
end
