Hi all,
I have a question:
I have a figure and I want to change the x axis (which are numbers from 1 to 48) to time scale, like this:
00:00 00:30 01:00......................23:30
any ideas?
thanks

In MATLAB R2014b or newer, try this:
>> t = duration(0:.5:23.5,0,0,'Format','hh:mm');
>> x = rand(size(t));
>> plot(t,x)
