Heatmap is used to plot rectangular data in matrix form with different colors. You can make a heatmap in Seaborn with the given code. I highly recommend you “Python Crash Course Book” to learn Python. In this article, you’ll see four examples in which you learn about these things.
- Seaborn Heatmap Colors
- Seaborn Heatmap Labels
- Seaborn Heatmap Title
- Seaborn Heatmap Font Size
- Seaborn Heatmap Size
Example 1: Heatmap
# Import the required libraries import numpy as np import seaborn as sns import matplotlib.pyplot as plt # Create NumPy Array data = np.random.randint(10, size=(10,5)) # Create simple Heatmap sns.heatmap(data) # Display the Heatmap plt.show()
Output:

Example 2: Seaborn Heatmap Colors
# Import the required libraries import numpy as np import seaborn as sns import matplotlib.pyplot as plt # Create NumPy Array data = np.random.randint(10, size=(10,5)) # Creat Heatmap with mention color sns.heatmap(data, cmap="Blues") # Other Colors you can try: Greens, BuPu, YlGnBu # Display the Heatmap plt.show()
Output:

Example 3: Seaborn Heatmap Title, Labels, Font Size
# Import the required libraries import numpy as np import seaborn as sns import matplotlib.pyplot as plt # Create NumPy Array data = np.random.randint(10, size=(10,5)) # Create Simple Heatmap sns.heatmap(data) # Set Title, Labels, Font Size plt.title('Heatmap of NumPy array', fontsize = 25) plt.xlabel('Horizontal Values', fontsize = 15) plt.ylabel('Vertical Values', fontsize = 15) # Display the Heatmap plt.show()
Output:

Example 4: Seaborn Heatmap Size
# Import the required libraries import numpy as np import seaborn as sns import matplotlib.pyplot as plt # Create NumPy Array data = np.random.randint(10, size=(10,5)) # Select Heatmap Size plt.figure(figsize=(15,5)) # Create simple Heatmap sns.heatmap(data) # Display the Heatmap plt.show()
