Seaborn clustermap row color with legend

Question

I found the following solution to add a row color legend to a Seaborn clustermap:

How to express classes on the axis of a heatmap in Seaborn

I have two related questions:

1. how to move the legend to the bottom of the clustermap?
2. if the index of the dataframe representing row_color has a a name, it appears as a label under the colored row. How to increase the fontsize of that label?

Answer 1

In order to add color legend, first, you need to create legend_TN .

import matplotlib.patches as mpatches
import seaborn as sns
legend_TN = [mpatches.Patch(color=c, label=l) for c,l in df[['tissue type','label']].drop_duplicates().values]

then g=sns.clustermap(...)

l2=g.ax_heatmap.legend(loc='center left',bbox_to_anchor=(1.01,0.85),handles=legend_TN,frameon=True)
l2.set_title(title='tissue type',prop={'size':10})
