You’re not plotting any specific values for your independent variables. I can’t tell from using matfile on ‘innovations.mat’ if there is a date vector. You have to plot a vector of datenumbers, then use datetick. See the documentation for the datetick function, particularity the discussion of ‘dateFormat’ under ‘Input Arguments’.

Can you give me an example here please?

Here is a way of doing it with months and days:

t = now + (1:7);
y = 2*t;

figure(1)
plot(t, y)
grid
datetick('x', 'dd/mm','keepticks')
xlabel('Date (day/month)')

it didn't help mate.

Post a representative vector of dates for your data. I do not have your date data so I cannot plot it by quarters.

See the documentation for datetick that I linked to in my Answer. It will give you the information you need.
