Key ideas in Interactive Dashboards with Power BI

  • Power BI visuals automatically communicate with each other on the same report page by default
  • Clicking an element like a bar or slice cross-filters or highlights related data in other charts on the canvas
  • A Power BI card visual displays a single standout aggregate value like total sales
  • A line chart displays continuous movement over time
  • A bar chart allows easy side-by-side comparison across discrete categories
  • Placing single-number KPI cards at the top gives users the executive summary at a glance
  • Placing charts in the middle reveals category patterns and trends
  • Placing detailed data tables at the bottom allows deeper drill-down without cluttering the initial overview
  • A slicer visual places user-facing filter buttons or dropdowns directly on the report canvas
  • Slicers let viewers filter dates or categories without opening the backend filter pane
  • Power BI tooltips let you show additional contextual metrics when hovering over a data point
  • Using a tooltip keeps the main visual clean and readable while still offering deep context on demand
  • Power Query records every cleaning action as a sequential step in the Applied Steps pane
  • Clicking 'Refresh' in Power BI automatically re-runs that entire sequence on the updated source data
  • Transformations are saved as a permanent recipe rather than one-off manual edits
  • Power BI visuals and slicers need values to sit in a single column to filter or aggregate over time
