Power BI provides interactive and insightful data visualization tools, among which the drill-down and drill-through functionalities stand out. These features provide users to navigate through different levels of data granularity which focus on mainly the specific insights.
Drill Down in Power BI
Drill-down functionality allows users to move to more levels within a hierarchy. This is especially useful for exploring data in hierarchical structures such as time (Year > Quarter > Month > Day) or organizational structures (Region > Country > City).
How to Set Up Drill Down
- Create a Hierarchy:
- In the Fields pane, drag and drop related columns (e.g., Year, Quarter, Month) to create a hierarchy.
- Enable Drill Down:
- In a visual (e.g., bar chart or table), click on the hierarchy icon to enable drill-down mode. This icon usually resembles a down arrow.
- Interact with the Visual:
- Click on data points to drill down into the next level of detail. For example, clicking on a year bar can show data for quarters within that year.
