Power BI for Data Analytics • Lesson 18 of 20
Filters, Slicers and Interactive Controls in Power BI
Learn how to use Power BI filters, slicers and interactive controls to explore data dynamically. Practice visual-level, page-level and report-level filtering, multi-selection, date slicers and visual interactions.
Interactive Power BI reports allow users to ask follow-up questions without creating a separate report for every scenario. Filters and slicers help narrow the analytical view, while visual interactions help users investigate relationships between categories, metrics and trends.

Understanding Filters
A filter limits the data shown in a Power BI visual or report. Filtering helps analysts focus on a particular category, region, product, customer group or time period.

Power BI Filters and Slicers for Data Analytics
Power BI filters and slicers are important tools for interactive data analysis. A filter can restrict the data shown in a visual, page or broader report context. A slicer places that filtering experience directly on the report canvas so users can make their own selections.
Visual-Level, Page-Level and Report-Level Filters
Different filter scopes solve different analytical problems. Visual-level filters are useful when only one chart needs a restriction. Page-level filters are useful when several visuals on the same page should respond to the same condition. Broader report filtering can be useful when a common analytical context is required.
Slicers and Interactive Controls
Slicers can be used for regions, products, customers, dates and other dimensions. Well-designed slicers make dashboards easier to explore because users can change the analytical context without editing the underlying data.
Visual Interactions and Data Exploration
Power BI visual interactions can allow selections in one visual to filter or highlight related information in another visual. This creates a more exploratory experience and helps analysts move from a high-level pattern to a more focused investigation.
Building an Interactive Power BI Dashboard
Effective interactive dashboard design starts with the business questions. Add controls that users genuinely need, make active filters understandable, use sensible filter scopes and provide a clear way to return to a broader view. The goal is not to add as many controls as possible, but to make data exploration easier.
