Hi,
I’m not sure to really understand your problem. On the link you have a function to calculate 2D FFT! Then if you want to calculate the FFT of your X array and your Y array you can do it really easily: split your array in 2 arrays, one for X and one for Y, calculate independently the 2 FFTs and built a new array.
Let me know if I understand your question and else please post your VI and give more details about your application.

Hi BenjaminR,
I have just X data to transform but I don't would like a FFT of time but a FFT of position (Y data).
My graph before the FFT is like this image.
If you require more information, let me know.

Hi,
Unfortunately, you don’t have any functions in LabVIEW to do that. You have to code this using math theory about Fourier Transform.
