Arguments --------- nn_intervals : list list of Normal to Normal Interval. normalize : bool Set to True to plot X axis as a cumulative sum of Time. Set to False to plot X axis using x as index array 0, 1, ..., N-1. autoscale : bool Option to normalize the x-axis as a time series for comparison. Set to True by default. y_min : float Custom min value might be set for y axis. y_max : float Custom max value might be set for y axis. úseaborn-darkgrid©é é©ZfigsizezRr Interval time seriesz Rr Intervalé©ÚfontsizeúTime (s)éèzRR-interval indexN) rÚuseÚpltÚfigureÚtitleÚylabelÚxlabelZplotÚnpZcumsumÚylimÚshowr ©r úO/var/www/html/bwave/python/venv/lib/python3.8/site-packages/hrvanalysis/plot.pyÚplot_timeseriess     r"r)r Ú bin_lengthcCs|t|ƒ}t|ƒ}t d¡tjddtjdddtjdddtjd ddtj |t |d |d |ƒd d t  ¡d S)a Function plotting histogram distribution of the NN Intervals.

Arguments --------- nn_intervals : list list of Normal to Normal Interval. method : str Method used to calculate the psd. Choice are Welch's FFT (welch) or Lomb method (lomb). sampling_frequency : int frequence at which the signal is sampled. Common value range from 1 Hz to 10 Hz, by default set to 7 Hz. No need to specify if Lomb method is used. interpolation_method : str kind of interpolation as a string, by default "linear". No need to specify if lomb method is used. vlf_band : tuple Very low frequency bands for features extraction from power spectral density. lf_band : tuple Low frequency bands for features extraction from power spectral density. hf_band : tuple High frequency bands for features extraction from power spectral density. )r r-r.r/réz VLF componentz LF componentz HF componentr rrzFrequency (Hz)rrz PSD (s2/ Hz)ZlombzLomb's periodogramr$r)ÚlabelÚsizeÚbest)ÚpropÚlocr+z"FFT Spectrum : Welch's periodogramz5Not a valid method.
