How to add a colorbar to kdeplot and jointplot

Question

When generating bivariate plots like hexbin, pandas generates a legend explaining frequency value for each color shade:

pokemon.plot.hexbin(x='HP', y='Attack', gridsize=30)

I cannot find a similar way to generate such a legend for jointplot and kdeplot in seaborn:

sns.jointplot(data=pokemon, x='HP', y='Attack', kind='hex')

sns.kdeplot(pokemon['HP'], pokemon['Attack'], shade=True)

How can I do it?

Answer 1

for a kdeplot, simply pass cbar=True

cbar : bool, optional

If True and drawing a bivariate KDE plot, add a colorbar.

import seaborn as sns

g = sns.jointplot(data=sns.load_dataset("penguins"), x="bill_length_mm", y="bill_depth_mm",
                  kind="kde", cbar=True, fill=True, height=8)
