In dashboards, filters can be global or local based on the scope of their effect:
1. Global Filter (Report-Level or Page-Level)
- Applies to all visuals on a report page or the entire report.
- Ensures consistent context across the dashboard.
- Example: A report-level filter for “Current Financial Year” ensures every chart only shows data for that year.
2. Local Filter (Visual-Level)
- Applies to a single visual only.
- Useful when one chart needs a specific subset of data without affecting others.
- Example: A bar chart showing only the Top 10 Products while the rest of the visuals show all products.
Using the right mix prevents confusion, maintains clarity, and supports focused analysis.
