pysteps.visualization.spectral.plot_spectrum1d¶

pysteps.visualization.spectral.plot_spectrum1d(fft_freq, fft_power, x_units=None, y_units=None, wavelength_ticks=None, color='k', lw=1.0, label=None, ax=None, **kwargs)¶

Function to plot in log-log a radially averaged Fourier spectrum.

Parameters

fft_freq: array-like: 1d array containing the Fourier frequencies computed with the function pysteps.utils.spectral.rapsd().
fft_power: array-like: 1d array containing the radially averaged Fourier power spectrum computed with the function pysteps.utils.spectral.rapsd().
x_units: str, optional: Units of the X variable (distance, e.g. “km”).
y_units: str, optional: Units of the Y variable (amplitude, e.g. “dBR”).
wavelength_ticks: array-like, optional: List of wavelengths where to show xticklabels.
color: str, optional: Line color.
lw: float, optional: Line width.
label: str, optional: Label (for legend).
ax: Axes, optional: Plot axes.

Returns

ax: Axes: Plot axes
