Step-by-Step Solution
Solution:
Step 1: Identify parameter for coloring by distance
'color_threshold' colors clusters below a distance threshold.Step 2: Confirm correct usage
Setting 'color_threshold=1.5' highlights clusters merged below 1.5 distance.Final Answer:
Set 'color_threshold=1.5' -> Option CQuick Check:
Use color_threshold to limit cluster coloring by distance [OK]
Quick Trick: Use color_threshold to highlight clusters by distance [OK]
Common Mistakes:
- Confusing truncate_mode with color threshold
- Using invalid parameter 'max_d'
- Misusing leaf_rotation for distance filtering
