I have 200 datapoints which I need to turn into 50 hours, trying to replicate the picture attached. What is the best way or function for doing this?

t = (1:200)/50;
plot(t, y)

Thank you for this answer - I was trying to use the date time function - as I need to see the hour when I zoom into the figure eg. picture
I was trying
ticlocs =
datetime(DateString);
ticlocs.Format = 'HH-MM';
set(gca, 'XTick', ticklocs);
But this is better- I was trying for a more automated way as I have lots of datasets at different lengths to convert to hours.
