Drill-Down

Navigating from summarized data to a more detailed level along a hierarchy, such as Year to Quarter to Month.

Definition

Drill-down keeps the same visual but shows finer granularity. Power BI and Tableau visuals support drill-down on hierarchies.

Example

Clicking 2026 in a column chart expands it into four quarters.

Exam tip

Drill-down changes the level within the same visual; drill-through jumps to a different, detailed page.
