Please post any details. What format does "the original date" have? What does "I made a plot" exactly mean and where do you want the "date" to appear?
The command datestr and datevec convert datenum values to other date formats. The command datetick writes nice dates instead of serial date numbers to the ticklables of axes.

Hi! the goal was to select 200 data from i big data. i took the time as a parameter
and converted it with datenum.
i wanted to plot the variation of selected measured data with the (date and time)
it will be for me nice to show also the date and time un the plot not only the converted eith datenum.
if true
%
date= time=
'1.2.2010' '1:2:59'
'2.2.2010' '2:3:50'
'5.2.2010' ......
... .......
... .....
.... .....
i converted them with datnum
converted=datenum(date)+datenum(time)

If you use "datenum" on a datetime array and want to get it converted back to datetime use the command below. It seem to work
"datetime(datestr(dates))"

Or more directly: datetime(dates,'ConvertFrom','datenum')
