What is Comparison Dashboard?

Comparison dashboard shows metrics side-by-side for comparison: this month vs last month, Plan A vs Plan B, Region 1 vs Region 2. Uses aligned columns or split view with matching metrics in same order. Highlights differences with up/down arrows, percentage changes, and visual contrast. Common in A/B testing and analytics platforms.

When Should You Use This?

A/B testing dashboards, time period comparisons (month-over-month, year-over-year), regional performance, plan comparisons. When users need to identify growth, decline, or performance gaps. Use matching metric order and visual alignment for easy scanning. Good for showing before/after or treatment/control results.

Common Mistakes to Avoid

• •Misaligned metrics—same metrics must line up vertically
• •No difference indicators—show % change and arrows
• •Too many comparison points—limit to 2-3 columns max
• •Missing context—label what's being compared clearly
