Combining two heatmaps in seaborn
To combine two heatmaps in seaborn, we can take the following steps −
Steps
Set the figure size and adjust the padding between and around the subplots.
Create two Pandas data frames.
Create a figure and a set of subplots, ax1 and ax2.
Plot the rectangular data as a color-encoded matrix, on ax1 and ax2.
Move ticks and ticklabels (if present) to the right of the axes.
Keep the width of the padding between subplots minimum, as a fraction of the average axes width.
To display the figure, use show() method.
Example
import matplotlib.pyplot as plt
import numpy as np
import pandas as pd
import seaborn as sns
plt.rcParams["figure.figsize"] = [7.50, 3.50]
plt.rcParams["figure.autolayout"] = True
df1 = pd.DataFrame(np.random.rand(10, 4), columns=list("ABCD"))
df2 = pd.DataFrame(np.random.rand(10, 4), columns=list("WXYZ"))
fig, (ax1, ax2) = plt.subplots(ncols=2)
fig.subplots_adjust(wspace=0.01)
sns.heatmap(df1, cmap="plasma", ax=ax1, cbar=False)
sns.heatmap(df2, cmap="hot", ax=ax2, cbar=False)
ax2.yaxis.tick_right()
fig.subplots_adjust(wspace=0.001)
plt.show()Output
It will produce the following output −
