spectrum-plot 0.2.0

Interactive spectrum plot. Update FFT plot on every new sampled data

spectrum plot

plotting FFT of 1D data, with live plot update

usage example:

import numpy as np
from spectrum_plot import create_fft_plot


plot = create_fft_plot()
n = 200
seconds = 0.1
t = np.linspace(0, seconds, n)
nyquist = n / seconds / 2
for freq in np.linspace(100, nyquist, 100):
    sine = np.sin(2 * np.pi * t * freq)
    plot.update_raw_data(sine, seconds=seconds)

In the examples folder, you can locate a code that includes the addition of music notes at the graph.
