💡 Hint

Common Mistakes

Using plt.show() instead of plt.legend()

Forgetting to add label in plot() before calling legend()

The legend() function adds a legend to the plot using the labels defined in the plot commands.

2fill in blank

medium

Complete the code to place the legend in the upper left corner.

Matplotlib

import matplotlib.pyplot as plt
plt.plot([1, 2, 3], label='Line')
plt.legend(loc=[1])
plt.show()

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

A'upper left'

B'upper right'

C'lower left'

D'center'

Attempts:

3 left

💡 Hint

Common Mistakes

Using 'upper right' instead of 'upper left'

Not using quotes around the location string

The loc parameter controls the legend position. 'upper left' places it in the top-left corner.

3fill in blank

hard

Fix the error in the code to set the legend font size to 14.

Matplotlib

import matplotlib.pyplot as plt
plt.plot([1, 2, 3], label='Line')
plt.legend(fontsize=[1])
plt.show()

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

A'14pt'

B'large'

C14

D14.0

Attempts:

3 left

💡 Hint

Common Mistakes

Passing font size as a string with units like '14pt'

Using a float instead of an integer

The fontsize parameter accepts an integer for font size in points, so 14 is correct.

4fill in blank

hard

Fill both blanks to place the legend at center left and set a shadow.

Matplotlib

import matplotlib.pyplot as plt
plt.plot([1, 2, 3], label='Line')
plt.legend(loc=[1], shadow=[2])
plt.show()

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

A'center left'

B'upper right'

CTrue

DFalse

Attempts:

3 left

💡 Hint

Common Mistakes

Using 'upper right' instead of 'center left'

Setting shadow to False or a string

Setting loc='center left' places the legend at center left, and shadow=True adds a shadow effect.

5fill in blank

hard

Fill all three blanks to create a legend with a title, placed at the lower center, and with fancy box style.

Matplotlib

import matplotlib.pyplot as plt
plt.plot([1, 2, 3], label='Line')
plt.legend(title=[1], loc=[2], fancybox=[3])
plt.show()

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

A'My Legend'

B'lower center'

CTrue

DFalse

Attempts:

3 left

💡 Hint

Common Mistakes

Not using quotes around the title string

Using incorrect location strings

Setting fancybox to False or a string

The title parameter adds a title to the legend, loc='lower center' places it at the bottom center, and fancybox=True gives the legend a rounded box style.
