Colorbar positioning in Matplotlib - Interactive Code Practice

Practice - 5 Tasks

1fill in blank

easy

Complete the code to add a colorbar to the plot.

Matplotlib

import matplotlib.pyplot as plt
import numpy as np

img = np.random.rand(10,10)
plt.imshow(img)
plt.colorbar(orientation=[1])
plt.show()

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

Alocation='top'

Borientation='horizontal'

Corientation='vertical'

Dlocation='left'

Attempts:

3 left

💡 Hint

Common Mistakes

Using location parameter instead of orientation

Setting orientation to horizontal when vertical is default

The default colorbar orientation is vertical, so specifying orientation='vertical' correctly adds a vertical colorbar.

2fill in blank

medium

Complete the code to place the colorbar on the right side of the plot.

Matplotlib

import matplotlib.pyplot as plt
import numpy as np

img = np.random.rand(10,10)
plt.imshow(img)
plt.colorbar(orientation=[1])
plt.show()

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

Aorientation='horizontal'

Blocation='bottom'

Clocation='right'

Dorientation='vertical'

Attempts:

3 left

💡 Hint

Common Mistakes

Using location='right' instead of orientation='vertical'

Setting orientation to horizontal which places colorbar at bottom

The default orientation is vertical, which places the colorbar on the right side by default.

3fill in blank

hard

Fix the error in the code to correctly position the colorbar below the plot.

Matplotlib

import matplotlib.pyplot as plt
import numpy as np

img = np.random.rand(10,10)
plt.imshow(img)
plt.colorbar(orientation=[1])
plt.show()

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

A'horizontal'

B'bottom'

C'right'

D'vertical'

Attempts:

3 left

💡 Hint

Common Mistakes

Using 'bottom' which is not a valid orientation value

Using 'vertical' which places colorbar on the side

To place the colorbar below the plot, orientation must be set to 'horizontal'.

4fill in blank

hard

Fill both blanks to create a horizontal colorbar below the plot with a label.

Matplotlib

import matplotlib.pyplot as plt
import numpy as np

img = np.random.rand(10,10)
im = plt.imshow(img)
cbar = plt.colorbar(im, orientation=[1], [2]='bottom')
cbar.set_label('Intensity')
plt.show()

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

A'horizontal'

B'vertical'

Clocation

Dlabel

Attempts:

3 left

💡 Hint

Common Mistakes

Using vertical orientation with bottom location

Using label parameter instead of location

orientation='horizontal' places the colorbar below, and location='bottom' explicitly sets its position.

5fill in blank

hard

Fill all three blanks to create a vertical colorbar on the left side with a label and shrink it.

Matplotlib

import matplotlib.pyplot as plt
import numpy as np

img = np.random.rand(10,10)
im = plt.imshow(img)
cbar = plt.colorbar(im, orientation=[1], [2]='left', shrink=[3])
cbar.set_label('Value')
plt.show()

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

A'horizontal'

B0.5

C'vertical'

Dlocation

Attempts:

3 left

💡 Hint

Common Mistakes

Using horizontal orientation with left location

Not using shrink parameter correctly

Using label instead of location

orientation='vertical' places the colorbar vertically, location='left' puts it on the left side, and shrink=0.5 reduces its size.
