A simple method plotting a Cumulative Distribution Function for a given array

cdf.py

def cdf(data, label, show = True):
    data_size=len(data)

    # Set bins edges
    data_set=sorted(set(data))
    bins=np.append(data_set, data_set[-1]+1)

    # Use the histogram function to bin the data
    counts, bin_edges = np.histogram(data, bins=bins, density=False)

    counts=counts.astype(float)/data_size

    # Find the cdf
    cdf = np.cumsum(counts)

    # Plot the cdf
    plt.plot(bin_edges[0:-1], cdf,linestyle='--', label=label)
    
    plt.ylabel('cdf')
    plt.legend()
    plt.show()
