How Do You Use a Radar Chart in Power BI?

How Do You Use a Radar Chart in Power BI?

You open the Visualizations pane in Power BI Desktop looking for the radar chart, the one shaped like a spider web, and it is not there. Every tutorial you find says Power BI does it. Microsoft's own documentation never mentions it.

Both are telling the truth, and the gap between them is the whole answer.

Is There a Radar Chart in Power BI?

Not as a built-in visual. Microsoft publishes a canonical list of the visualization types Power BI offers, and the words radar, spider, polar and star chart do not appear anywhere on it.

What the list does contain is organised by job: bar and column, line, area, combo and ribbon charts for comparison and trends; pie, donut, treemap and funnel for part-to-whole; scatter, bubble and dot plot for distribution; tables and matrices; cards, KPIs, gauges and goals; the AI visuals, including decomposition tree and key influencers; slicers; and a set of utility visuals from image and text box through to Q&A.

No radar. But the same page closes the door and opens another one, stating that beyond built-in visuals you can download additional visuals from Microsoft AppSource or create your own custom visuals.

That is where the radar chart lives. And Microsoft publishes one itself.

Microsoft Publishes a Radar Chart It Does Not Document

The Radar Chart on AppSource is Microsoft's. Its package manifest names the author as Microsoft, with a Microsoft support address, and the visual currently ships as version 3.1.3.0 built against visuals API 5.8.0.

The source repository is public and active, not archived, and carries no deprecation notice of any kind.

The AppSource listing describes it in one line: multiple measures plotted over a categorical axis, useful to compare attributes. That is the only description of the chart type you will find on a Microsoft property.

The listing also states that the visual is certified by Power BI. Hold onto that word.

The deprecation story you may have found is about something else

Search for a Power BI radar chart and you will eventually land on a GitHub repository of old .pbiviz files with "sunset" in its name, containing a radar chart at version 0.5.6. It looks like evidence that Microsoft killed the visual.

It is not. That repository belongs to a personal account, not to the Microsoft organization, and it describes itself as a collection of Power BI custom visuals from before the move to the Office Store.

A 0.5.6 package from the pre-marketplace era sitting next to a live 3.1.3.0 release is an archive, not a tombstone.

There is a real deprecation in this area, and it is narrower.

Microsoft announced the end of support for custom visual API version 1.1 and older, after which report authors saw a warning in Power BI Desktop reading that the visual is using an old and unsupported version of interface and will be deprecated soon, and telling them to replace it with an alternative from the in-house or marketplace visuals.

Worth saying plainly: there is no Microsoft announcement anywhere that deprecates or withdraws its own community visuals as a batch. If you have read that somewhere, nobody has sourced it.

How Do You Add the Radar Chart to a Report?

Microsoft documents one procedure, and it covers Power BI Desktop and the Power BI service together.

Open your report in Power BI Desktop or the Power BI service. Select the ellipsis from the Visualizations pane. Choose Get more visuals from the menu. Select AppSource visuals and pick the visual you want to import. Select Add, then OK once the import succeeds.

The visual then appears as a new icon at the bottom of the Visualizations pane, for the current report only. To keep it, right-click the icon and select Pin to visualization pane, which ties it to your signed-in account so new reports include it automatically.

One detail worth knowing before you go hunting in the ribbon: Microsoft documents only the Visualizations-pane route. The Insert > More visuals path that several tutorials state confidently does not appear in Microsoft's import documentation at all.

If you import from a file instead

Downloading a .pbiviz and loading it directly is a different procedure with an extra step most write-ups omit.

You must first enable developer mode for Power BI Desktop, and Microsoft is explicit that this setting stays enabled for the current session only and must be repeated every time you import a visual from a file.

You then use Import a visual from a file from the same ellipsis menu, accept the caution about importing custom files, and open the package.

Microsoft's own warning is worth quoting: custom visuals that come from sources other than official Microsoft sources should be imported only if you trust the source.

What Certification Actually Changes

Certification is not a quality badge and it is not a safety rating. Microsoft defines certified visuals as those in AppSource that meet the Power BI team's code requirements and testing, with the tests designed to check that the visual does not access external services or resources.

In the same breath Microsoft adds that it is not the author of third-party custom visuals and advises customers to contact the author directly to verify functionality.

What certification buys you is capability. Microsoft states that certified visuals offer more features than non-certified ones, giving export to PowerPoint and display in subscription emails as the examples.

Read the export documentation and the consequence sharpens considerably. Power BI custom visuals are not supported for export to PowerPoint, with the exception of those that are certified, and the export option is either greyed out or absent.

The same exclusion applies to PDF export, and for report subscriptions the unsupported visuals display an error symbol.

That is the practical punchline. Pick an uncertified radar chart and you have not just chosen a chart, you have quietly disabled PowerPoint export, PDF export and clean subscriptions for the whole page.

Microsoft is also careful about the inverse: visuals that are not certified are not necessarily unsafe. Some simply cannot be certified, because a map visual has to call an external service or because the visual uses commercial libraries.

Verifying certification is harder than it should be

Microsoft's certification page explains the concept and the requirements in detail, and maintains no list. It names no certified visual and no publisher.

The only way it offers to check is a filter inside the product, selecting the Power BI Certified option, plus the badges: yellow on an AppSource card, blue when the visual is imported from within Power BI.

So a reader cannot verify any given visual's certification status from Microsoft's documentation. You confirm it on the marketplace card or in the product, and nowhere else.

When Is a Radar Chart the Right Choice?

The honest answer is narrower than its popularity suggests, and the AppSource one-liner is the best guide available: comparing several measures across one categorical axis, where the shape of the whole profile is the point.

It earns its place for scorecard comparisons on a fixed, small set of axes: vendor evaluations across five or six weighted criteria, or skill and maturity assessments. Cases where a reader should see "strong here, weak there" as one silhouette rather than reading six numbers in sequence.

It is the wrong tool when the axes are not comparable, when there are many categories, when you need precise value reading, or when the underlying question is about change over time.

A radar chart makes differences look dramatic or trivial depending on axis order, and axis order is usually arbitrary.

Limitations Worth Knowing Before You Commit

Three constraints apply to any custom visual, and they bite later rather than at design time.

Your tenant may forbid it. Microsoft documents an admin setting to allow visuals created using the Power BI SDK, and a second setting to add and use certified visuals only, which blocks uncertified ones outright.

A third setting governs whether custom visuals may download information available to them.

Deploying through your organization's repository costs you features rather than gaining them. Microsoft states that organizational visuals cannot be exported to PowerPoint or displayed in subscription emails, and that only certified visuals imported directly from the marketplace support those features.

Organizational visuals are also not supported in Power BI Report Server. And deleting one from the repository is not reversible: reports using it stop rendering.

Report Server has a floor and a network dependency. Custom visuals only work with Power BI Report Server versions released after May 2021, and Power BI Desktop for Report Server needs to reach pbivisuals.powerbi.com on port 443 to load the current copy of a visual, which is why an offline or firewalled machine shows a visual that loads forever and never appears.

Two further gaps are worth naming rather than guessing at. Microsoft's developer guidance for mobile states that a visual must render on all supported mobile devices, but no Microsoft page says whether custom visuals are supported in the Power BI mobile apps.

And Microsoft's own troubleshooting page for visualizations does not cover custom or AppSource visuals at all, so a radar chart that will not render sends you nowhere useful.

On licensing, Microsoft confirms that AppSource visuals carry several business models, with some offering free trials and others a free basic version plus paid functionality.

The failure mode matters: open a report using a visual you are not licensed for and the visual does not render, showing a button to get a license or contact the report owner.

What Are the Native Alternatives?

If a marketplace dependency is unwelcome, Microsoft documents built-in visuals that serve the same underlying job.

The closest native match is the combo chart, which Microsoft describes as combining a column chart and a line chart to let you compare multiple measures with different value ranges, with one or two Y axes. That is the radar chart's actual problem stated in Microsoft's own words.

A line chart on a categorical axis is the substitute most often recommended elsewhere. It works, and Microsoft never endorses it: the visualization-types page says line charts work best with continuous data along the X axis, and the line chart page defines the Categorical and Continuous axis Type option without ever saying when categorical is preferable for a non-date field.

Multiple measures are supported as a static series by adding each to the Y-axis well, but Microsoft notes that charts with multiple measures in the Y-axis do not support adding a field to the Legend.

Small multiples is the other common suggestion, and it is simply unavailable here. Microsoft states that small multiples can currently be created on bar, column, line and area charts, which excludes every custom visual.

Final Thoughts

Power BI's radar chart is real, current, published by Microsoft and certified.

It is also absent from Microsoft's own list of visualization types, documented only by a one-line marketplace tagline, and reachable only through a procedure that lives in the developer section of the documentation rather than next to the screenshot that promises it.

Treat the chart choice as secondary. The decision that will actually surface in a stakeholder's inbox is certification, because that is what determines whether the page exports to PowerPoint, exports to PDF, and arrives in a subscription without an error symbol.

Check the badge before you build the report, not after someone asks for the deck.

And if you are enabling visual types in Power BI more broadly, the same admin and tenant settings govern other visuals too, as our guide to how to enable map visuals in Power BI walks through.
