I would like to report more dates: for example every month or every week
I use plot to draw it..(
plot(Ax_Sys,XDates(locs(:,i)),sig,'DisplayName',STR_name{i},'Color',SumCTR_color(i,:),'LineWidth',1);)

Ran in:
load matlab_Xdates
load matlab_TeStrum
load matlab_fig
Ax_Eq.Parent
ans =
0x0 empty GraphicsPlaceholder array.
Somehow, you have an axes that has no Parent, so gca is creating a new axes, and that new axes defaults to numeric.
You should also be specific about the axes to parent graphics operations to.
legend_lines(1)=plot(Ax_Eq,XDates,TE_strum(:,1));
xtickformat(Ax_Eq, 'MMM u' );% DA SISTEMARE
xticks(Ax_Eq, XDates(1):calmonths(1):XDates(end));% DA SISTEMARE

The last line,
___ = xticks(ax,___)
is indicating that you can pass an axes as the first parameter.

Use xticks
If you must report every week, then you will probably want to use xtickangle

I can't duplicate your error, and I show an example that works with the expected data.
Please share all the data used to create your figure. Consider saving your variables to a mat file and attaching it to your post using the paperclip icon. Since you are specifiying a target axis, it would be insightful to see all relevant code.

Ok i try to send it
legend_lines(1)=plot(Ax_Eq,XDates,TE_strum(:,1));
xtickformat( 'MMM u' );% DA SISTEMARE
xticks(XDates(1):calmonths(1):XDates(end));% DA SISTEMARE
Error using xtickformat (line 34)
Invalid numeric tick label format.
Error in untitled2 (line 7)
xtickformat( 'MMM u' );
