additional row colors in seaborn cluster map

Question

I am currently generating clustermaps in seaborn and labeling the row colors as below.

matrix = pd.DataFrame(np.random.random_integers(0,1, size=(50,4)))
labels          


        

Answer 1

I tried to concat the row_colors dataframe by pandas and it worked! Please try this code:

import seaborn as sns; sns.set(color_codes=True)
import matplotlib.pyplot as plt
import pandas as pd

iris = sns.load_dataset("iris")
print(iris)
species = iris.pop("species")


lut1 = dict(zip(species.unique(), ['#ED2323','#60FD00','#808080']))
row_colors1 = species.map(lut1)

lut2 = dict(zip(species.unique(), "rbg"))
row_colors2 = species.map(lut2)

row_colors = pd.concat([row_colors1,row_colors2],axis=1)
print(row_colors)

g = sns.clustermap(iris, row_colors=row_colors, col_cluster=False,cmap="mako", yticklabels=False, xticklabels=False)

plt.show()
