Hi all,
I want to plot confidence level for FFT analysis of currents. Do anybody know how to plot confidence level in ferret or matlab or origin ? Any help is appreciated.

Thanks in advance.

With best regards,

Hello
you can refer
Torrence, C., and G.P. Compo, A practical guide to wavelet analysis, Bull. Am. Meteorol. Soc., 79, 61-78, 1998.
which is a good tool for spectral analysis.
thanks,
