Which of the following is the correct way to enable downsampling with the 'min' method in a matplotlib Line2D object?

line = plt.plot(x, y)[0]
# Enable downsampling here
Aline.set_downsample(True, method='min')
Bline.set_downsample('min')
Cline.set_downsample(True); line.set_downsample_method('min')
Dline.set_downsample('min', True)
Step-by-Step Solution
Solution:
  1. Step 1: Recall matplotlib downsampling syntax

    Matplotlib's Line2D supports set_downsample(True, method='min') to enable downsampling with a method.
  2. Step 2: Check options for correct syntax

    line.set_downsample(True, method='min') matches the correct method signature exactly.
  3. Final Answer:

    line.set_downsample(True, method='min') -> Option A
  4. Quick Check:

    Correct method call = line.set_downsample(True, method='min') [OK]
Quick Trick: Use set_downsample(True, method='min') to enable min downsampling [OK]
Common Mistakes:
  • Using set_downsample with only one argument
  • Trying to set method separately
  • Passing method as first argument
