Text boxes with bbox in Matplotlib - Mini Project: Build & Apply

Text Boxes with bbox in Matplotlib

📖 Scenario: You are creating a simple plot to show some data points and want to add text labels with colored boxes around them to highlight important information.

🎯 Goal: Build a Matplotlib plot with text labels that have colored bounding boxes (bbox) around them to make the text stand out clearly.

📋 What You'll Learn

Create a plot with Matplotlib

Add text labels at specific coordinates

Use bbox parameter to add colored boxes around the text

Customize the box color and style

💡 Why This Matters

🌍 Real World

Text boxes with bounding boxes are useful in data visualization to highlight important points or annotations clearly on charts and graphs.

💼 Career

Data scientists and analysts often annotate plots to explain insights, making their visualizations easier to understand for stakeholders.

1

Create a basic plot with data points

Import matplotlib.pyplot as plt. Create two lists called x and y with values [1, 2, 3] and [4, 5, 6] respectively. Plot these points using plt.scatter(x, y).

Matplotlib

# Your code here

Need a hint?

Use plt.scatter to plot points from lists x and y.

2

Add a text label with a bounding box

Add a text label at coordinates (1, 4) with the text 'Point A' using plt.text. Use the bbox parameter to add a box with facecolor='lightblue' and edgecolor='blue'.

Matplotlib

import matplotlib.pyplot as plt
x = [1, 2, 3]
y = [4, 5, 6]
plt.scatter(x, y)
# Add text with bbox here

Need a hint?

Use plt.text(x, y, text, bbox=dict(...)) to add text with a colored box.

3

Add more text labels with different bbox styles

Add two more text labels: one at (2, 5) with text 'Point B' and a red box with facecolor='mistyrose' and edgecolor='red', and another at (3, 6) with text 'Point C' and a green box with facecolor='honeydew' and edgecolor='green'.

Matplotlib

import matplotlib.pyplot as plt
x = [1, 2, 3]
y = [4, 5, 6]
plt.scatter(x, y)
plt.text(1, 4, 'Point A', bbox=dict(facecolor='lightblue', edgecolor='blue'))
# Add two more text labels with different bbox styles here

Need a hint?

Add two plt.text calls with different bbox colors.

4

Display the plot with all text boxes

Add plt.show() to display the plot with all points and text boxes.

Matplotlib

import matplotlib.pyplot as plt
x = [1, 2, 3]
y = [4, 5, 6]
plt.scatter(x, y)
plt.text(1, 4, 'Point A', bbox=dict(facecolor='lightblue', edgecolor='blue'))
plt.text(2, 5, 'Point B', bbox=dict(facecolor='mistyrose', edgecolor='red'))
plt.text(3, 6, 'Point C', bbox=dict(facecolor='honeydew', edgecolor='green'))
# Show the plot below

Need a hint?

Use plt.show() to display the plot window.
