Hello everyone,
I would like to plot the first plot you can see here with the "%other plots" that you see in the code, but I got an error.
Can anyone help me please?
Thank you.

errorbar() does support datetime inputs
https://www.mathworks.com/help/matlab/ref/errorbar.html#bvc1i62-1-y
The problem is that you are plotting year first, and the year you plot is pure numeric, 1998+something. Once you have plotted numeric in an axes, you cannot plot datetime or categorical in the same axes.
The workaround is to turn the year into datetime objects,
Years = datetime(Years, 1, 1, 'Format', 'yyyy')

I do not encounter any problem.

LD = load('giulia_TT.mat');
giulia_TT = LD.giulia_TT;

N=GIULIA_YEARLY_N.Var5*3.5;
SelIdx = year(GIULIA_YEARLY_N.Time) >= 1998; % Logical Mask Vectror
N_Sel = N(SelIdx);
N_Sel_Dif = -diff(N_Sel);
Years = 1998+(1:numel(N_Sel_Dif));
Years = datetime(Years, 1, 1, 'Format', 'yyyy');
figure
plot(Years, N_Sel_Dif)

errorbar() doesn't support datetime inputs. You'll end up needing to avoid that, which might complicate things a bit:

but it's weird, because on my matlab I can plot this plots separately, but not all together.
