Box and Whisker plot using Python Libraries

Step 1: Install Necessary Libraries

First, make sure you have matplotlib and seaborn installed. You can install them using pip:

pip install matplotlib seaborn

#clcoding.com

Step 2: Import Libraries

Next, import the necessary libraries in your Python script or notebook.

import matplotlib.pyplot as plt
import seaborn as sns
import numpy as np

Step 3: Create Sample Data

Create some sample data to plot. This can be any dataset you have, but for demonstration purposes, we will create a simple dataset using NumPy.

# Generate sample data
np.random.seed(10)
data = [np.random.normal(0, std, 100) for std in range(1, 5)]

Step 4: Create the Box and Whisker Plot

Using matplotlib and seaborn, you can create a basic Box and Whisker plot.

# Create a boxplot
plt.figure(figsize=(10, 6))
plt.boxplot(data, patch_artist=True)

# Add title and labels
plt.title('Box and Whisker Plot')
plt.xlabel('Category')
plt.ylabel('Values')

# Show plot
plt.show()

Step 5: Enhance the Plot with Seaborn

For more advanced styling, you can use seaborn, which provides more aesthetic options.

# Set the style of the visualization

sns.set(style="whitegrid")

# Create a boxplot with seaborn

plt.figure(figsize=(10, 6))

sns.boxplot(data=data)

# Add title and labels

plt.title('Box and Whisker Plot')

plt.xlabel('Category')

plt.ylabel('Values')

# Show plot

plt.show()
