Pandas: Visualization Integration Exercise-9 with Solution

Write a Pandas program to plot multiple line plots in one figure with Pandas.

This exercise demonstrates how to plot multiple line plots in one figure using Pandas and Matplotlib.

Sample Solution :

Code :

import pandas as pd
import matplotlib.pyplot as plt

# Create a sample DataFrame
df = pd.DataFrame({
    'Year': [2017, 2018, 2019, 2020, 2021],
    'Product_A': [200, 250, 300, 350, 400],
    'Product_B': [150, 200, 250, 300, 350]
})

# Plot multiple lines for Product A and Product B
plt.plot(df['Year'], df['Product_A'], label='Product A', marker='o')
plt.plot(df['Year'], df['Product_B'], label='Product B', marker='s')

# Add labels and title
plt.xlabel('Year')
plt.ylabel('Sales')
plt.title('Sales of Product A and B Over Time')

# Add a legend
plt.legend()

# Display the plot
plt.show()

Output:

Explanation:

• Created a DataFrame with sales data for two products across different years.
• Plotted two line plots in the same figure for 'Product_A' and 'Product_B'.
• Added labels, a title, and a legend to the plot.
• Displayed the final plot.
