Hi twilight,

Your timestamp within the file is a string, right?

I have to assume that you are using a text file and not a spreadsheet.

In the case of a text file, you can use Concatenate Strings to place the data one after the other following the timestamp. You can include a delimiter, suchs as a space (in this case), so that you can read the file.  You could actually use a tab, which would make the file wider in some text editor, but easier to read.

The trick is to NOT include an end of line character "\r" "\n" (or combo) until you have concatenated all the data for that line, then place a single end of line constant at the end of each sample... Hopefully, I'm not confusing you...  😉

Example: 

10:20:34  data1 data2 data3 ... data_n "end-of-line"

10:26:34  data1 data2 data3 ... data_n "end-of-line"

that mean you wnat be add end of line character as last one in the conating of strings!

I modified your vi, please consider carefully the changes... it may not be exactly what you want to do, but it's an improvement.

I have a question,

In my VI , i wanted mean of values for every second.

i mean , when my DAQ board gives some 1000 samples per second. i need mean of these 1000 samples,but not all 1000 sanmples.
for this i included a elapsed time vi with taget of 1s. (didnt forget to reset after 1s).

but what i see is it gives values at every milli second. to be more clear

12:12:01     d1 d2 d3
12:12:01     d1 d2 d3

but i need like
12:12:01   d1 d2 d3
12:12:02   d1:d2:d3
 did i go any where wrong in my Vi.
