Fill density plots with color

I have two density plot, one above the other. How can I fill the area under the curves with 2 different colors and also add some transparency so that the overlapped region is noticeable.

import numpy as np
import pandas as pd 
import matplotlib.pyplot as plt
import sys 
import seaborn as sns

x=[1,1,1,1,1,1,1,0,0,0,0,0,0,0]
y=[1,1,1,0,2,0,0,0,1,1,0,1,0,1]
sns.distplot(x, hist=False,color="green")
sns.distplot(y, hist=False,color="blue")

enter image description here

Solution

  • Have you tried sns.kdeplot(x, hist=False, color="green", shade=True)? Apparently they create the same curve.

    From what I can tell it is transparent by default, which should fulfill your requirements.

    import matplotlib.pyplot as plt
import seaborn as sns

x=[1,1,1,1,1,1,1,0,0,0,0,0,0,0]
y=[1,1,1,0,2,0,0,0,1,1,0,1,0,1]
sns.kdeplot(x, color="green", shade=True)
sns.kdeplot(y, color="blue", shade=True)
plt.show()

    Here is the resulting graph:
