Matplotlib - Performance and Large Data

You want to combine downsampling with interactive zooming in matplotlib. Which approach is best?

AUse downsampling only after zooming is finished

BDisable downsampling to avoid losing detail during zoom

CUse downsampling with 'min' method and enable interactive pan/zoom

DUse downsampling with 'mean' and disable zoom

Step-by-Step Solution

Solution:

Step 1: Understand interaction with zoom
Downsampling reduces points but interactive zoom needs fast redraws.
Step 2: Choose method that preserves detail and speed
'min' method preserves important features and speeds rendering during zoom.
Step 3: Evaluate other options
Disabling downsampling slows redraw; delaying downsampling complicates code; disabling zoom reduces usability.
Final Answer:
Use downsampling with 'min' method and enable interactive pan/zoom -> Option C
Quick Check:
