How to plot FFT using Matlab – FFT of basic signals : Sine and Cosine waves | GaussianWaves 2. FFT plot – plotting raw values against Normalized Frequency axis: In the next version of plot, the frequency axis (x-axis) is normalized to unity. Just divide the sample index on the x-axis by the length \(N\) of the FFT. This normalizes the x-
