Axes vs pyplot interface comparison in Matplotlib - Interactive Practice

Practice - 5 Tasks

1fill in blank

easy

Complete the code to create a line plot using pyplot interface.

Matplotlib

import matplotlib.pyplot as plt
plt.plot([1, 2, 3], [4, 5, 6])
plt.[1]()

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

💡 Hint

Common Mistakes

Using plt.draw() instead of plt.show() which does not display the plot window.

Calling plt.figure() which creates a new figure but does not display the plot.

The plt.show() function displays the plot window when using pyplot interface.

2fill in blank

medium

Complete the code to create a figure and axes using the object-oriented interface.

Matplotlib

import matplotlib.pyplot as plt
fig, [1] = plt.subplots()
[1].plot([1, 2, 3], [3, 2, 1])
plt.show()

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

Baxes

Cax

Dfigure

💡 Hint

Common Mistakes

Using 'figure' instead of 'axes' which is the wrong object for plotting.

Using 'axis' which is not the correct variable name returned by plt.subplots().

plt.subplots() returns a figure and axes object; the axes object is commonly named 'ax'.

3fill in blank

hard

Fix the error in the code by choosing the correct method to set the title using the axes object.

Matplotlib

import matplotlib.pyplot as plt
fig, ax = plt.subplots()
ax.plot([1, 2, 3], [3, 2, 1])
ax.[1]('My Plot')
plt.show()

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

Alabel

Btitle

Csetlabel

Dset_title

💡 Hint

Common Mistakes

Using ax.title() which does not exist for axes objects.

Using ax.label() which is unrelated to titles.

The axes object uses set_title() method to set the plot title.

4fill in blank

hard

Fill both blanks to create a scatter plot using the axes interface and set x and y labels.

Matplotlib

import matplotlib.pyplot as plt
fig, ax = plt.subplots()
ax.[1]([1, 2, 3], [4, 5, 6])
ax.[2]('X axis')
ax.set_ylabel('Y axis')
plt.show()

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

💡 Hint

Common Mistakes

Using ax.plot() instead of ax.scatter() for scatter plot.

Using ax.xlabel() which is not a method.

Use ax.scatter() to create scatter plot and ax.set_xlabel() to set x-axis label.

5fill in blank

hard

Fill all three blanks to create a bar chart using pyplot, set title and y label.

Matplotlib

import matplotlib.pyplot as plt
plt.[1](['A', 'B', 'C'], [5, 7, 3])
plt.[2]('Category Counts')
plt.[3]('Count')
plt.show()

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

Dplot

💡 Hint

Common Mistakes

Using plt.plot() instead of plt.bar() for bar chart.

Using plt.xlabel() instead of plt.ylabel() for y-axis label.

Use plt.bar() for bar chart, plt.title() for title, and plt.ylabel() for y-axis label.
