PL-300 Visualize and analyze the data Practice Question
You are building a report to analyze sales performance by region. You need to allow users to dynamically switch between viewing data as a bar chart and a line chart without modifying the report page. Which feature should you use?

Correct answer & explanation
✓
Use bookmarks with buttons to toggle between charts.
The correct option is A: use bookmarks with buttons to toggle between charts. In Power BI, bookmarks capture the current state of a report page—including visual visibility and chart type—so pairing two bookmarks (one showing the bar chart, one showing the line chart) with buttons lets users switch views dynamically without editing the report page. Slicers (B) filter data and cannot change a visual's chart type, and no standard slicer offers chart-type switching. A custom visual (C) is not required and would not provide the native toggle behavior described. Drillthrough pages (D) navigate to a filtered detail page rather than toggling the chart type in place.
Answer analysis
Option-by-option breakdown
For each option: why learners choose it and why it is or isn't the right answer here.
- ✓
Use bookmarks with buttons to toggle between charts.
Why this is correct
Bookmarks capture the current state of a report page, including which visual is visible. Assigning bookmarks to buttons lets users toggle between the bar chart and line chart views without editing the page, satisfying the dynamic switching requirement within a single report page.
- ✗
Add a slicer that changes the chart type.
Why it's wrong here
A slicer filters data by field values; it cannot alter a visual's chart type. Switching between bar and line rendering requires a bookmark or the field parameter feature, which swaps the visual's configuration. Slicers are the right choice when users must filter rows by category, date or region.
- ✗
Use a custom visual with built-in toggle.
Why it's wrong here
A custom visual with a toggle depends on third-party code and still requires the visual to be authored or imported; it is not the native mechanism for switching chart types. Bookmarks or field parameters switch rendering using built-in report features. Custom visuals suit bespoke visualisations unavailable in the standard gallery.
- ✗
Create a drillthrough page for each chart type.
Why it's wrong here
Drillthrough navigates to a separate page filtered to a selected data point; it does not toggle a visual's chart type in place. The requirement is switching rendering without leaving or editing the page, which bookmarks or field parameters accomplish. Drillthrough suits detailed per-item breakdowns, not chart-type switching.
