SuccessfulKoala55 Ok. Here is my code. Thanks.
` def plot_feature_scatter(df1, df2, features):
i = 0
sns.set_style("whitegrid")
plt.figure

fig, ax = plt.subplots(5, 4, figsize=(20, 20))

for feature in features:
    i += 1
    plt.subplot(5, 4, i)
    plt.scatter(df1[feature], df2[feature], marker="+", color='#2B3A67', alpha=0.2)
    plt.xlabel(feature, fontsize=9)
    
plt.show()

plot_feature_scatter(train_df.sample(50000), test_df.sample(50000), features) `
