Use switch to cut a waveform

[joc31]

I try to cut a waveform when the curve value is greater than a threshold value.

I use a switch and I generate the cut signal 0 (FALSE) for return 0  and 1 (TRUE) to return the value of the waveform.

But I have a null waveform as result !!  

Do you have an idea because when I use a switch on the front panel, the result is well but manual !

See attach files. 

Thanks

I am not sure if I understand you problem correct. But see if this VI helps

Y[i]=Clip{X[i]} VI
Owning Palette: Signal Operation VIs

Installed With: Full Development System

Clips the elements of Input Array to within the bounds specified by upper limit and lower limit.

I have modified Vi with clip and It's work fine.

Thank you very much.
