代碼如下：

def plot_feature_distribution(df1, df2, label1, label2, features):i = 0sns.set_style('whitegrid')plt.figure()fig, ax = plt.subplots(10,5,figsize=(18,22))for feature in features:i += 1plt.subplot(10,5,i)sns.kdeplot(np.log(df1[feature]), bw=0.5,label=label1)sns.kdeplot(np.log(df2[feature]), bw=0.5,label=label2)plt.xlabel(feature, fontsize=9)locs, labels = plt.xticks()plt.tick_params(axis='x', which='major', labelsize=6, pad=-6)plt.tick_params(axis='y', which='major', labelsize=6)plt.show();

用法如下：
