Which of the following is the correct way to create a 3D scatter plot axis in matplotlib?
Aax = plt.axes(projection='3d')
Bax = plt.subplots(projection='3d')
Cax = plt.figure(projection='3d')
Dax = plt.subplot(projection='3d')
Step-by-Step Solution
Solution:
  1. Step 1: Recall how to create 3D axes

    In matplotlib, plt.axes(projection='3d') creates a 3D axes object.
  2. Step 2: Check other options

    plt.subplot and plt.subplots do not accept projection directly; plt.figure creates a figure, not axes.
  3. Final Answer:

    ax = plt.axes(projection='3d') -> Option A
  4. Quick Check:

    Use plt.axes with projection='3d' for 3D axes [OK]
Quick Trick: Use plt.axes(projection='3d') to get 3D axes [OK]
Common Mistakes:
  • Using plt.subplot instead of plt.axes for 3D
  • Passing projection to plt.figure instead of axes
  • Confusing plt.subplots with plt.subplot
