plot_distrib fails about hrv-analysis

[robinchampseix]

Hi,

Thanks for raising this issue :-) Yep I will try to do that soon.
It is actually due to the fact that the method expects a list of int as input.

For those still waiting, you can fix it by simply casting the max and min values to int's (as range expects int values not floats). By doing something like:

def plot_distrib(nn_intervals, bin_length: int = 8):
    """
    Function plotting histogram distribution of the NN Intervals. Useful for geometrical features.
    Arguments
    ---------
    nn_intervals : list
        list of Normal to Normal Interval.
    bin_length : int
        size of the bin for histogram in ms, by default = 8.
    """

    max_nn_i = max(nn_intervals)
    min_nn_i = min(nn_intervals)

    style.use("seaborn-darkgrid")
    plt.figure(figsize=(12, 8))
    plt.title("Distribution of Rr Intervals", fontsize=20)
    plt.xlabel("Time (s)", fontsize=15)
    plt.ylabel("Number of Rr Interval per bin", fontsize=15)
    #Range expects an integer rather than a float
    plt.hist(nn_intervals, bins=range(int(min_nn_i) - 10, int(max_nn_i) + 10, bin_length), rwidth=0.8)
    plt.show()
