[FIXED] Gradient color for kdeplot

Issue

I'm looking to plot a gradient of color that represents the density in seaborn 0.12.x Before it seems that the argument cmap was accepted : Add labels to Seaborn bivariate KDE plot It seems to not be the case in the 0.12.x https://seaborn.pydata.org/generated/seaborn.kdeplot.html and I don't manage to create a similar graph in 0.12.x Here is a quick example :

a = np.random.random((1000,))
b = np.random.random((1000,))
df = pd.DataFrame(np.random.randint(0, 100, size=(1000, 2)), columns=list('AB'))
ax = sns.kdeplot(x='A', y='B',
                 # cmap="Greens",
                 data=df)
plt.show()

Note that I don't want to have filling, I'm really looking to have only lines.

Solution

This was a bug introduced in 0.12.0; there is a fix in the master branch and it will be released with 0.12.1 in the next week or so.
