Viewing angle control in Matplotlib - Interactive Code Practice

Practice - 5 Tasks

1fill in blank

easy

Complete the code to set the elevation angle of the 3D plot to 30 degrees.

Matplotlib

ax.view_init(elev=[1], azim=45)

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

💡 Hint

Common Mistakes

Confusing elevation with azimuth angle.

Using values outside the typical 0-90 degree range.

The elev parameter controls the elevation angle in degrees. Setting it to 30 changes the vertical viewing angle.

medium

Complete the code to set the azimuth angle of the 3D plot to 120 degrees.

Matplotlib

ax.view_init(elev=20, azim=[1])

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

💡 Hint

Common Mistakes

Mixing up elevation and azimuth values.

Using negative values without understanding their effect.

The azim parameter controls the horizontal rotation angle in degrees. Setting it to 120 rotates the view horizontally.

Fix the error in the code to correctly set the viewing angle with elevation 45 and azimuth 135.

Matplotlib

ax.view_init(elev=45, azim=[1])

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

💡 Hint

Common Mistakes

Passing azimuth as a string instead of a number.

Using variable names instead of numeric values.

The azim parameter must be a number, not a string or variable name. Use 135 without quotes.

4fill in blank

hard

Fill both blanks to create a 3D plot with elevation 60 and azimuth 90.

Matplotlib

fig = plt.figure()
ax = fig.add_subplot(111, projection='3d')
ax.view_init(elev=[1], azim=[2])
plt.show()

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

💡 Hint

Common Mistakes

Swapping elevation and azimuth values.

Using incorrect numeric values.

Set elev to 60 for vertical angle and azim to 90 for horizontal rotation.

5fill in blank

hard

Fill all three blanks to create a 3D scatter plot with elevation 25, azimuth 135, and set the marker style to 'o'.

Matplotlib

fig = plt.figure()
ax = fig.add_subplot(111, projection='3d')
ax.view_init(elev=[1], azim=[2])
ax.scatter(x, y, z, marker=[3])
plt.show()

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

💡 Hint

Common Mistakes

Using quotes incorrectly for numeric values.

Choosing wrong marker styles.

Set elevation to 25, azimuth to 135, and marker style to 'o' for circle markers.
