Pie chart color customization in Matplotlib - Mini Project: Build & Apply

Pie chart color customization

📖 Scenario: You are working with sales data for different fruits in a small grocery store. You want to show the sales distribution using a pie chart. To make the chart clearer and more attractive, you want to customize the colors of each slice.

🎯 Goal: Create a pie chart that shows the sales of fruits with custom colors for each fruit slice.

📋 What You'll Learn

Create a dictionary called fruit_sales with exact fruit names and sales numbers.

Create a list called colors with exact color names matching the fruits order.

Use matplotlib's plt.pie() function with the colors parameter to customize slice colors.

Print the pie chart with a title 'Fruit Sales Distribution'.

💡 Why This Matters

🌍 Real World

Pie charts are often used in business to show parts of a whole, like sales distribution among products.

💼 Career

Data analysts and scientists use pie charts to communicate data insights clearly to stakeholders.

1

Create the fruit sales data

Create a dictionary called fruit_sales with these exact entries: 'Apples': 30, 'Bananas': 15, 'Cherries': 45, 'Dates': 10.

Matplotlib

# Create the fruit_sales dictionary with exact values
# Your code here

Need a hint?

Use curly braces {} to create a dictionary with keys as fruit names and values as sales numbers.

2

Create the colors list

Create a list called colors with these exact color names in order: 'red', 'yellow', 'pink', 'brown'.

Matplotlib

fruit_sales = {'Apples': 30, 'Bananas': 15, 'Cherries': 45, 'Dates': 10}
# Create the colors list with exact color names
# Your code here

Need a hint?

Use square brackets [] to create a list of color names as strings.

3

Create the pie chart with custom colors

Import matplotlib.pyplot as plt. Use plt.pie() with fruit_sales.values() as data and colors=colors to set slice colors. Add labels using fruit_sales.keys(). Add a title 'Fruit Sales Distribution' using plt.title().

Matplotlib

fruit_sales = {'Apples': 30, 'Bananas': 15, 'Cherries': 45, 'Dates': 10}
colors = ['red', 'yellow', 'pink', 'brown']
# Import matplotlib.pyplot as plt
# Create pie chart with fruit_sales values and colors list
# Add labels from fruit_sales keys
# Add title 'Fruit Sales Distribution'
# Your code here

Need a hint?

Remember to import matplotlib.pyplot as plt first. Use the colors parameter inside plt.pie() to customize colors.

4

Display the pie chart

Use plt.show() to display the pie chart.

Matplotlib

import matplotlib.pyplot as plt

fruit_sales = {'Apples': 30, 'Bananas': 15, 'Cherries': 45, 'Dates': 10}
colors = ['red', 'yellow', 'pink', 'brown']

plt.pie(fruit_sales.values(), labels=fruit_sales.keys(), colors=colors)
plt.title('Fruit Sales Distribution')
# Display the pie chart
# Your code here

Need a hint?

Use plt.show() to make the pie chart appear on the screen.
