See
doc datenum
doc datetick
and examples thereat
ADDENDUM:
OK at machine w/ a minute...try
>> dn=datenum(datevec(t,'dd/mm/yy HH:MM:SS')); >> plot(dn,rand(size(dn))) >> datetick('x','keeplimits','keepticks')
NB: I cleaned up the above data strings that had tab here and there down to a single space; use format as needed for the actual form.

I hope it is clear now:
DateTime{1,1} = '31/08/97 03:03:32'; %
DateTime{1,2} = '31/08/97 03:07:39'; %
Yvalue = [3 4]; % Example values
ts1 = timeseries(Yvalue,DateTime); % Create a timeseries object whit oure yvalue %and the time scale
ts1.Name = 'Warming up off ... '; % Give it a name
plot(ts1); % Create a plot of it.
grid ('on');
