How to set x-axis into HH:MM format?

I have a double of 21x1 which corresponds to the air temperature over time. The time is a cell (21x1) containing the hour at which the temperature was measured, in the format HH:MM. The measurements were taken every 10 minutes from 03:20 to 06:40. How do I plot (scatterplot) temperature vs time?

It will be much easier for us to help you if you upload the data in a MAT file, rather than just describing it.

It's just two vecors tho, like:

A = [ 24 25 26 27 24 24 24]

B = [ 02:20 02:30 02:40 02:50 03:00 03:10 03:20]

and I'd like to plot A against B

The advantage of actually uploading the data is that you do not inadvertently make MATLAB statements such as

B = [ 02:20 02:30 02:40 02:50 03:00 03:10 03:20]

B = 1×162

2 3 4 5 6 7 8 9 10 11 12 13 14 15 16 17 18 19 20 2 3 4 5 6 7 8 9 10 11 12

that are clearly not defining times.

The B that you list in your snippet doesn't look like times. Here's an example where B is actually a time:

A = [24 25 26 27 24 24 24];
B = datetime('now') + minutes(10:10:70);
scatter(B,A,'filled')
