Visualize and Analyze the Data
Match the visual to the question
Bar and column charts compare categories, line charts show trend over time, scatter shows correlation between two measures, cards and KPIs show a single value, matrices give a cross-tab with drill-down, slicers act as filter controls. Questions often reward the boring correct answer over the showy one: many categories belong in a bar chart, not a pie; time belongs on an X axis, not a category axis.
Filter hierarchy and interactions
Filters apply at visual, page and report level, plus slicer selections and the filter cards on drill-through and tooltip pages. Edit interactions decides whether a selection cross-highlights, filters or is ignored. Sync slicers use a group and can be pushed across pages, with the visible slicer on the target page refreshed automatically.
Drill down versus drill through
Drill down needs a hierarchy or several fields on the axis and moves within one visual. Drill through needs a separate destination page containing the drill-through field, optionally with Keep all filters, so the destination keeps the source page's filters. These two are swapped constantly in exam items.
Reports, dashboards and interactivity
A report is multi-page and lives in a workspace; a dashboard is a single page of tiles pinned from one or more reports and cannot host slicers. Bookmarks capture filter, slicer and visibility state, which is how buttons build navigation and how you build a toggle. Report page tooltips replace default hover tooltips when you set them.
Worked example
A user must click a country in a bar chart and land on a detail page already filtered to that country. Build a drill-through page, put Country in the drill-through well, enable Keep all filters. Rule of thumb: within one visual, drill down; across pages, drill through.
