Understanding Custom Visuals Installation

You want to add a new custom visual from the Power BI marketplace to your report. What is the correct first step?

A Open the Visualizations pane and click on the 'Get more visuals' icon to browse the marketplace.

B Download the visual from an external website and import it directly without using Power BI interface.

C Create a new visual from scratch using DAX expressions in the report canvas.

D Use the Power Query Editor to add the custom visual as a data source.

💡 Hint

Think about where Power BI provides access to official custom visuals.

DAX Measure Behavior with Custom Visuals

You created a DAX measure that calculates total sales. You use a custom visual from the marketplace that supports drill-down. What happens to your measure when you drill down in the visual?

Power BI

Total Sales = SUM(Sales[Amount])

A The measure always shows the grand total sales regardless of drill-down.

B The measure recalculates to show total sales only for the drilled-down category or level.

C The measure returns an error because custom visuals do not support DAX measures.

D The measure shows the average sales instead of total sales when drilled down.

💡 Hint

Think about how DAX measures respond to filters applied by visuals.

DAX measures recalculate dynamically based on the current filter context, including drill-down selections in visuals, custom or built-in.

Choosing the Best Custom Visual for Time Series Data

You want to visualize monthly sales trends over two years with the ability to highlight specific months. Which custom visual from the marketplace is best suited for this task?

A Use the 'KPI Indicator' visual to show only the current month's sales value.

B Use the 'Chiclet Slicer' visual to filter data by months in a grid layout.

C Use the 'Timeline Storyteller' visual to create an interactive timeline with highlight features.

D Use the 'Card Browser' visual to display sales values as cards without trend lines.

💡 Hint

Look for a visual that supports time-based data and interactive highlighting.

'Timeline Storyteller' is designed for time series data and allows users to highlight and explore specific time periods interactively, making it ideal for monthly sales trends.

Troubleshooting Custom Visual Import Failure

You try to import a custom visual (.pbiviz file) downloaded from the marketplace, but Power BI shows an error: 'Visual import failed due to unsupported version.' What is the most likely cause?

A The .pbiviz file is corrupted and cannot be opened by Power BI.

B The visual requires an internet connection, but your computer is offline.

C You did not enable the 'Allow custom visuals' option in Power BI settings.

D The custom visual was built for a newer Power BI version than your desktop supports.

💡 Hint

Consider compatibility issues between software versions.

Power BI desktop may reject visuals built for newer versions if your software is outdated. Updating Power BI usually resolves this.

Designing a Dashboard with Multiple Custom Visuals

You are designing a sales dashboard using three different custom visuals from the marketplace. You want all visuals to interact with each other so that selecting data in one filters the others. What must you ensure for this to work correctly?

A All custom visuals must support cross-filtering and be configured to allow interactions in the report settings.

B You must write custom DAX code to link the visuals manually for interaction.

C Custom visuals cannot interact with each other; only built-in visuals support interaction.

D You need to import all visuals from the same developer to ensure compatibility.

💡 Hint

Think about how visuals communicate filter changes in Power BI.

Custom visuals that support cross-filtering can interact if report interactions are enabled. No extra code or same developer requirement is needed.

Practice

1. What is the main purpose of using custom visuals from the Power BI marketplace?

easy

A. To create data tables without any visuals

B. To replace all default visuals permanently

C. To export data to Excel automatically

D. To add new and unique ways to display data beyond default charts

Solution

1. Step 1: Understand default visuals in Power BI

   Power BI offers standard charts like bar, line, and pie charts by default.

2. Step 2: Role of custom visuals

   Custom visuals from the marketplace provide additional, unique ways to show data that default visuals don't offer.

3. Final Answer:

   To add new and unique ways to display data beyond default charts -> Option D

4. Quick Check:

   Custom visuals = new display options [OK]

Hint: Custom visuals extend default charts with new display types [OK]

Common Mistakes:

• Thinking custom visuals replace default visuals permanently
• Confusing custom visuals with data export features
• Assuming custom visuals create data tables only

2. Which of the following is the correct way to add a custom visual from the Power BI marketplace?

easy

A. Right-click on a chart and choose 'Convert to custom visual'

B. Download visuals from an external website and import manually without Power BI

C. Click on the 'Get more visuals' icon in the Visualizations pane and select a visual

D. Use the 'Export' option in the File menu

Solution

1. Step 1: Locate the Visualizations pane in Power BI

   The Visualizations pane has an icon to get more visuals from the marketplace.

2. Step 2: Use 'Get more visuals' to browse and add

Hint: Use 'Get more visuals' icon inside Power BI to add custom visuals [OK]

Common Mistakes:

• Trying to convert default charts to custom visuals directly
• Downloading visuals outside Power BI without import
• Looking for export options to add visuals

3. You added a custom visual from the marketplace to your report. What will happen if you share this report with someone who does not have that custom visual installed?

medium

A. The visual will show as a blank or error icon

B. The visual will display correctly without any issue

C. The report will not open at all

D. The visual will convert automatically to a default chart

Solution

1. Step 1: Understand custom visual dependencies

   Custom visuals require the receiving user to have the visual installed or supported in their Power BI environment.

2. Step 2: Behavior when visual is missing

   If the visual is missing, Power BI cannot render it, so it shows a blank or error icon instead.

3. Final Answer:

   The visual will show as a blank or error icon -> Option A

4. Quick Check:

   Missing custom visual = blank/error icon [OK]

Hint: Missing custom visual shows blank or error icon [OK]

Common Mistakes:

• Assuming visuals convert automatically to default charts
• Thinking report won't open at all
• Believing visuals always display correctly without installation

4. You tried to add a custom visual from the marketplace but received an error saying the visual is not certified. What should you do to fix this?

medium

A. Delete all visuals and start a new report

B. Check if the visual is certified and consider using a certified alternative

C. Restart Power BI to clear the error

D. Ignore the error and continue using the visual anyway

Solution

   It's best to check certification status and choose a certified visual to avoid risks and errors.

3. Final Answer:

   Check if the visual is certified and consider using a certified alternative -> Option B

4. Quick Check:

   Certification error = use certified visual [OK]
