Practice - 5 Tasks

1fill in blank

easy

Complete the code to save the figure as a PNG file named 'plot.png'.

Data Analysis Python

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

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

💡 Hint

Common Mistakes

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

Trying to save the figure before plotting

Misspelling the function name

The savefig function saves the current figure to a file. Here, it saves it as 'plot.png'.

2fill in blank

medium

Complete the code to save the figure with a resolution of 300 dots per inch (DPI).

Data Analysis Python

import matplotlib.pyplot as plt
plt.plot([1, 2, 3], [4, 5, 6])
plt.savefig('plot.png', [1]=300)

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

Aresolution

Bquality

Cdpi

Dsize

Attempts:

3 left

💡 Hint

Common Mistakes

Using 'quality' or 'resolution' instead of 'dpi'

Not specifying the dpi parameter at all

Using an invalid parameter name

The dpi parameter sets the resolution of the saved figure in dots per inch.

3fill in blank

hard

Fix the error in the code to save the figure as a PDF file named 'figure.pdf'.

Data Analysis Python

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

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

Asavefig

Bexport

Csave

Dshow

Attempts:

3 left

💡 Hint

Common Mistakes

Using plt.save() or plt.export() which are not valid functions

Using plt.show() instead of saving

Misspelling the function name

The correct function to save figures in matplotlib is savefig. Other options like save or export do not exist.

4fill in blank

hard

Fill both blanks to save the figure as a JPEG file with a transparent background.

Data Analysis Python

import matplotlib.pyplot as plt
plt.plot([1, 2, 3], [4, 5, 6])
plt.savefig('image.jpg', [1]=[2])

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

Atransparent

BTrue

CFalse

Dalpha

Attempts:

3 left

💡 Hint

Common Mistakes

Using 'alpha' instead of 'transparent' for background transparency

Setting transparent to False instead of True

Confusing parameter names

The transparent parameter set to True saves the figure background as transparent.

5fill in blank

hard

Fill all three blanks to save the figure as a high-quality SVG file with a tight bounding box.

Data Analysis Python

import matplotlib.pyplot as plt
plt.plot([1, 2, 3], [4, 5, 6])
plt.savefig('diagram.svg', [1]=300, [2]='[3]')

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

Adpi

Bbbox_inches

Ctight

Dquality

Attempts:

3 left

💡 Hint

Common Mistakes

Using 'quality' instead of 'dpi'

Not setting bbox_inches to 'tight'

Misspelling parameter names

Use dpi for resolution, bbox_inches set to 'tight' to reduce extra whitespace around the figure.
