How can you display an image so that it fills the plot area with axes limits set to [0, 8] and [0, 4], stretching pixels accordingly?
ASet aspect='equal' and extent=[0, 4, 0, 2]
BSet aspect='equal' and extent=[0, 8, 0, 4]
CSet aspect='auto' and use extent=[0, 4, 0, 2]
DSet aspect='auto' and extent=[0, 8, 0, 4]
Step-by-Step Solution
Solution:
  1. Step 1: Understand stretching with aspect='auto'

    Aspect='auto' allows image pixels to stretch to fill axes limits.
  2. Step 2: Match extent to axes limits

    Using extent=[0,8,0,4] with axes limits [0,8],[0,4] and aspect='auto' stretches image to fill plot.
  3. Final Answer:

    Set aspect='auto' and extent=[0, 8, 0, 4] -> Option D
  4. Quick Check:

    Aspect='auto' stretches image to fit axes [OK]
Quick Trick: Aspect='auto' stretches image to fill axes [OK]
Common Mistakes:
  • Using aspect='equal' which keeps pixel size fixed
  • Changing extent to axes limits without aspect='auto'
  • Assuming extent alone controls stretching
