Saving current time during measurement

[alican]

Hi, 

I would like to save time when i started measurement. is it possible to first saving data and time, then showing them on graph, on y axis datas, on x axis, time(not current time, but time when i saved during measurement.)

thanks a lot.

Hi alican,

yes, that possible (all of it). You have to program it! 😄

Hints:

- depending on your file format you might want to convert timestamp to string using FormatDateTimestring

- you might want to save your data too, not just the timestamp 🙂

If you get your data in the waveform format, have a look at the t0 value 😉

If wire the wfrm to a graph, the x axis will start with that t0 value (unless you don't tell to ignore the timestamp)

hi

i made this program, it produce random number and save it with current time. 

how i will plot in in second program, i get problem about accesing one coloum, of array seperately. i put things what i did, maybe solution is so simple but i cant see.

thanks in advance

hi again, 

a bit prograss, but there i problem to read time value from text. 

time is like 16:34:23 but it read it like 16,000. what kind conversion do i need to do?

thanks.

i was looking at your programs and trying to make sense of it all...i cleaned it up to a compact version of what you are trying to do. save the file as a .CSV delimeter. see if it makes any sense?

yes, display format time x-axis drop down box for custom time format at the graph properties...

Time in Excel has a different epoch (base date) and scale than LabVIEW uses.  Use the Time to XL.vi found here (don't forget to vote)
