subplot(2,1,1)

I don't recall when Mathworks introduced the Exponent property to the axes; but you can forcibly turn it off.
NOTA BENE that Exponent is a property of the [X|Y|Z]Axis and is not visible from just the hAx handle.
NOTA BENE SECOND: Unless later versions have fixed it, the mode with a datetime or duration axis is not exposed; one has to make a subterfuge fixup to remove the equivalent there of the date if only want the times on the axis visible.
