What is Matplotlib - Hands-On Activity

What is Matplotlib

📖 Scenario: You want to create simple pictures from data to understand it better. Imagine you have numbers about daily temperatures and want to see them as a line going up and down. This helps you see patterns quickly.

🎯 Goal: Learn how to use Matplotlib to make a simple line chart from a list of numbers.

📋 What You'll Learn

Create a list of numbers representing data

Import Matplotlib's pyplot module

Use pyplot to make a line chart from the data

Show the chart on the screen

💡 Why This Matters

🌍 Real World

People use Matplotlib to see patterns in data like sales, weather, or sports scores.

💼 Career

Data scientists and analysts use Matplotlib to explain data clearly to others.

1

Create a list of numbers

Create a list called temperatures with these exact values: [22, 24, 19, 23, 25, 20, 21].

Matplotlib

# Create the list called temperatures with the given values
# Your code here

Need a hint?

Use square brackets [] to make a list and separate numbers with commas.

2

Import Matplotlib's pyplot

Write the exact line import matplotlib.pyplot as plt to import pyplot from Matplotlib and call it plt.

Matplotlib

temperatures = [22, 24, 19, 23, 25, 20, 21]
# Import matplotlib.pyplot as plt
# Your code here

Need a hint?

Use the exact import statement to access plotting functions easily.

3

Create a line chart from the data

Use plt.plot(temperatures) to create a line chart from the temperatures list.

Matplotlib

temperatures = [22, 24, 19, 23, 25, 20, 21]
import matplotlib.pyplot as plt
# Create a line chart from temperatures
# Your code here

Need a hint?

Use the plot function from plt and pass the list of numbers.

4

Show the chart on the screen

Use plt.show() to display the line chart you created.

Matplotlib

temperatures = [22, 24, 19, 23, 25, 20, 21]
import matplotlib.pyplot as plt
plt.plot(temperatures)
# Show the chart
# Your code here

Need a hint?

Call the show function to open a window with your chart.
