      1. Use a custom conditional formatting formula:

=AND(B2>=PERCENTILE(B:B, 0.9), E2="In Progress")

• • • 1. Apply the rule to the entire dataset.

• Dynamic Icon Sets:

  • Add icons (e.g., arrows or traffic lights) to indicate sales performance:

    • Green for >400.

    • Yellow for 300–400.

    • Red for <300.

    • Prompt: “How do I apply icon sets to visualize sales performance?”
