Bubble charts concept in Matplotlib - Interactive Code Practice

Practice - 5 Tasks

1fill in blank

easy

Complete the code to create a basic bubble chart using matplotlib.

Matplotlib

import matplotlib.pyplot as plt
x = [1, 2, 3, 4]
y = [10, 20, 25, 30]
sizes = [100, 200, 300, 400]
plt.scatter(x, y, s=[1])
plt.show()

Drag options to blanks, or click blank then click option'

💡 Hint

Common Mistakes

Using x or y instead of sizes for the bubble size parameter.

Forgetting to pass the sizes list to the s parameter.

The s parameter in plt.scatter sets the size of the bubbles. We use the sizes list to control bubble sizes.

medium

Complete the code to add colors to the bubbles in the chart.

Matplotlib

import matplotlib.pyplot as plt
x = [1, 2, 3, 4]
y = [10, 20, 25, 30]
sizes = [100, 200, 300, 400]
colors = ['red', 'blue', 'green', 'purple']
plt.scatter(x, y, s=sizes, c=[1])
plt.show()

💡 Hint

Common Mistakes

Passing sizes or coordinates instead of colors to the c parameter.

Not passing any colors, resulting in default colors.

The c parameter in plt.scatter sets the colors of the bubbles. We use the colors list to assign colors.

Fix the error in the code to correctly display the bubble chart with labels.

Matplotlib

import matplotlib.pyplot as plt
x = [1, 2, 3, 4]
y = [10, 20, 25, 30]
sizes = [100, 200, 300, 400]
labels = ['A', 'B', 'C', 'D']
plt.scatter(x, y, s=sizes)
for i, label in enumerate(labels):
    plt.text(x[i], y[i], [1])
plt.show()

💡 Hint

Common Mistakes

Using labels[i] instead of label inside the loop.

Using labels which is the whole list, not a single label.

Inside the loop, label holds the current label. Use it to place text on the chart.

4fill in blank

hard

Fill both blanks to create a bubble chart with transparency and a title.

Matplotlib

import matplotlib.pyplot as plt
x = [1, 2, 3, 4]
y = [10, 20, 25, 30]
sizes = [100, 200, 300, 400]
plt.scatter(x, y, s=sizes, alpha=[1])
plt.[2]('My Bubble Chart')
plt.show()

Drag options to blanks, or click blank then click option'

B0.8

Ctitle

💡 Hint

Common Mistakes

Using xlabel instead of title for the plot title.

Setting alpha to a value greater than 1 or less than 0.

The alpha parameter controls transparency; 0.5 means 50% transparent. The title function adds a title to the plot.

5fill in blank

hard

Fill all three blanks to create a bubble chart with edge colors, a grid, and axis labels.

Matplotlib

import matplotlib.pyplot as plt
x = [1, 2, 3, 4]
y = [10, 20, 25, 30]
sizes = [100, 200, 300, 400]
plt.scatter(x, y, s=sizes, edgecolors=[1])
plt.grid([2])
plt.xlabel([3])
plt.show()

Drag options to blanks, or click blank then click option'

A'black'

BTrue

C'X Axis'

D'none'

Attempts:

3 left

💡 Hint

Common Mistakes

Using 'none' for edgecolors which removes edges.

Passing False to plt.grid which hides the grid.

Not passing a string to plt.xlabel.

edgecolors='black' adds black edges to bubbles. plt.grid(True) shows grid lines. plt.xlabel('X Axis') labels the x-axis.
