How to get the smooth curve in Fig.5

[nuomizai]

Hi, I'm very interested in NPPAC and I'd like to take it as a comparison method. However, I got stuck in the evaluation metric. How to get the smooth curve as that in Fig. 5? I can only get a unsmooth curve with rllab.

def sliding_mean(data_array, window=5):
    data_array = np.array(data_array)
    new_list = []
    for i in range(len(data_array)):
        indices = list(range(max(i - window + 1, 0),
                             min(i + window + 1, len(data_array))))
        avg = 0
        for j in indices:
            avg += data_array[j]
        avg /= float(len(indices))
        new_list.append(avg)

    return np.array(new_list)
