I was running seaborn ver. 0.10.1 on my jupyter notebook. This morning I upgraded to the latest version 0.11.0. Now, my kde jointplot doesn't give the color mapping that it used to. The code is the same. Only the versions are different.
import numpy as np
import pandas as pd
import matplotlib.pyplot as plt
import seaborn as sns
%matplotlib notebook
np.random.seed(1234)
v1 = pd.Series(np.random.normal(0,10,1000), name='v1')
v2 = pd.Series(np.random.normal(60,15,1000), name='v2')
v3 = pd.Series(2*v1 + v2, name='v3')
# set the seaborn style for all the following plots
sns.set_style('white')
sns.jointplot(v1, v3, kind='kde', space=0);
