WebDec 4, 2024 · 1 Answer. The problem you're seeing is because the bars are too wide, and you're only seeing one bar. You will have to change the width of the bars to 0.00001 or smaller to see them show up. Instead of using a bar chart, make your x axis using fftfreq = np.fft.fftfreq (len (s)) and then use the plot function, plt.plot (fftfreq, fft):
