datenum and date conversion

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.

is there any possibilty to do this?

    % code
    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)

thanky

It is hard for me to read your message. What exactly is the goal? Where do you select what?

Use

datetick

to show date and time in the axis of the plot.. (if that what you meant..)

date = [
    '1.2.2010'
    '2.2.2010'
    '5.2.2010']
time = [
    '1:2:59'
    '2:3:50'
    '5:4:59']

out = datenum(strcat(date,{' '},time),'dd.mm.yyyy HH:MM:SS');
