How can I compare two heatmaps using Seaborn?

You can compare two heatmaps in Seaborn by overlaying them or using subplots. Would you like a code example?

Yes, please provide a code example for overlaying heatmaps.

Sure! You can use the sns.heatmap() function and adjust the alpha for transparency. Here's a sample code:

import seaborn as sns
import matplotlib.pyplot as plt

# Sample data
data1 = [[1, 2], [3, 4]]
data2 = [[4, 3], [2, 1]]

plt.figure(figsize=(8, 6))

# First heatmap
sns.heatmap(data1, alpha=0.5, cmap='Blues')

# Second heatmap
sns.heatmap(data2, alpha=0.5, cmap='Reds')

plt.show()

What if I want to use subplots instead?

You can use plt.subplot() to create subplots for each heatmap. Here's how:

plt.figure(figsize=(12, 6))

# First subplot
plt.subplot(1, 2, 1)
sns.heatmap(data1, cmap='Blues')
plt.title('Heatmap 1')

# Second subplot
plt.subplot(1, 2, 2)
sns.heatmap(data2, cmap='Reds')
plt.title('Heatmap 2')

plt.show()
