how to chang  cluster of 2 elements( 2 measurement data 1 D array of (double[64-bit])) to dynamic data?

I need to do FFT transform, the input data type for FFT transform is dynamic data type, but the waveform from XY graph which time value is set by X axis and amplitude is bst by Y axis.

thank you for all your help

Hi jing,

you have to create a waveform. I changed your example. if your time values do not have the same dt you have to interpolate it first.
