xtickat = 0:60:length(YourData)-1; %every hour from 00:00
set(gca, 'XTick', xtickat, 'XTickLabel', cellstr( num2str( mod(round(xtickat .' ./ 60),24) ) ) )
This will use hour 0, 1, 2, ... 23, 0, 1, 2, ... 23, and so on, with no indication of the day of the week (as the question asked for x axis to be in 24 hour, not for day and hour)
This will try to produce 168 ticks, which might perhaps be too much for your purposes. If so you can increase the 60 in xtickat to a more appropriate number such as 360 (6 hours).

mod(round(xtickat .' ./ 60),24)
would become
1 + mod(round(xtickat .' ./ 60) - 1,24)

Something along the lines of:
set(gca,'xticklabel',num2cell(num2str((0:2:22)'),2)')

Why use num2cell for that?
set(gca, 'xticklabel', cellstr( num2str((0:2:22).') ) )
However, this has the problem that you need exactly the matching number of Xtick values

CELLSTR is sweet (and new to me!). I'd heard of ISCELLSTR, but not CELLSTR.
