how to convert 1-D array double to double?

[AllanNish]

Being a novice to LabVIEW, I'm not sure how to convert a 1-D array of double to double to display. I'm trying to display a time stamp from a waveform to a double precision display.

I would appreciate any help!

Thank you!!!

If it is a waveform data type, you use the Get Waveform Components to extract t0. You would need to use a To Double Precision Float to convert the timestamp.

You can't "convert" a 1D array to a single value. You can index out an element to a single value. Or you can perform some mathematical operation, like the average value. However, you said you have a waveform, so it sounds to me like what you really should be looking at are the waveform-related functions. Specifically, Get Waveform Components. This will allow you to get the starting time for the waveform, and wire it directly to a timestamp indicator. Is this what you need?

EDIT: Dennis posted while I was, so you got a double answer.

Hi!

Thank you for the quick reply!

I've tried converting the time array, but I can't seem to display it on the standard double precision display.

I've attached the error.

Thank you for your help!!!

Interesting attempt with Flatten To String, but ditch all of that.  After you convert the Time Array to DBL, simply Right-click on the thick orange wire (Array of DBL) and Choose Create->Indicator.

And why are you doing all of that instead of just getting t0?

Your idea to "dump the idea" led me to try another approach. I used the "time stamp" vi, and that did what I wanted to do all along!

Thank you for your help!!

This is a great forum. I really appreciate your help!

Your suggestion to "ditch all that" was a great one. I tried a different approach, that of using the "elapsed time" vi, and that did the trick! It's doing exactly what I wanted it to do.

Thanks so much for your help! This is a great forum!!!
