How do I control the format of the date stamp on a plot axis with datetime values?

Hi,
I have some data with timestamps, so I have plotted values on the y-axis versus a datetime array on the x-axis.
I really like that Matlab summarized the date for me, since all the ticks have the date in common, only a different time. Similarly, it will summarize the year if all ticks have this in common. However, how do I control the format of this extra label on the axis, in this case the date? I can control the format of the xticks, but that is not what I'm looking for. I would like to display the date differently (eg 'd MMMM yyyy'), instead of the 'MMMM d, yyyy' that it is now.

That is named the secondary label and has some rather rudimentary controls, e.g.:
Unfortunately to control its format you will need to dig into some undocumented features... and (AFAIK) we will have to modify the text after the plot command. Lets try now:
X = datetime(2024,2,13,0:23,0,0);
Y = rand(1,numel(X));
plot(X,Y)
A = gca;
drawnow() % the forum requires this
S = A.XRuler.SecondaryLabel.String
D = datetime(S, 'InputFormat','MMM d, y', 'Format','d MMMM yyyy')
A.XRuler.SecondaryLabel.String = char(D);
hold on
plot(0,0) % required to update the forum plot

Tip: go to the xSecondaryLabel page (linked at the top of my answer), scroll to the very bottom, give a rating (of your choice) together with the feedback that the function needs to include the ability to change the date format.
