I have the following code-

y=repmat([10,20,30,15,25],10,1);
bar(y,'stacked',LineStyle='none');
id=cellstr(num2str([1:size(y,2)].','A%d'));
h=legend(id,'Location','northoutside','Orientation','horizontal',FontSize=13)

This gives the output as-

I want to have the legend in two rows and center aligned at the northoutside.

How do I do that?

Note, I have tried -

h.NumColumns=2;

This gives-

What I want is like this-

A1 A2

A3 A4 A5.

Please note, these must be center aligned.

gives handles to the different text and patch objects situated in the legend. You could modify the positions to have the centered appearance that you describe.
