Matplotlib - Performance and Large Data

What is wrong with the following code that tries to enable downsampling with the 'max' method?

line = plt.plot(x, y)[0]
line.set_downsample(True)
line.set_downsample_method('max')

Aline must be a scatter plot, not a line plot

Bset_downsample_method is not a valid method for Line2D

CDownsampling cannot use 'max' method

Dset_downsample must be called with method argument

Step-by-Step Solution

Solution:

Step 1: Check Line2D API for downsampling
Line2D has set_downsample but no set_downsample_method method.
Step 2: Identify correct way to set method
The method must be set as argument in set_downsample(True, method='max').
Final Answer:
set_downsample_method is not a valid method for Line2D -> Option B
Quick Check:
No set_downsample_method method = set_downsample_method is not a valid method for Line2D [OK]

Quick Trick: Set method inside set_downsample, no separate method exists [OK]
