| Principle | Poor practice | Better practice |
|---|---|---|
| Start with a question | Create charts because they look interesting | Define the monitoring or reporting question first |
| Show denominators | Show percentages only | Show counts and percentages together |
| Preserve missingness | Drop missing values silently | Label missing or explain exclusions |
| Use meaningful scales | Hide units or use distorted axes | Label axes and use appropriate ranges |
| Avoid clutter | Use many colors and unnecessary effects | Use restrained visual design |
| Support action | Show vague trends | Make priority issues visible |
