Radar Chart for Power BI
AI-generated radar chart for Power BI. Describe what you need in plain English; download a ready-to-import .pbiviz file. Full TypeScript source included.
A radar chart (also called a spider or web chart) plots multiple axes radiating from a shared center and connects each entity's values into a closed polygon. It's the right tool when you need to compare a handful of entities across many dimensions at once — a product against its competitors on 8 feature scores, a job candidate's skills profile, a balanced-scorecard KPI vs. target across quarters.
Power BI has no native radar. AppSource has several, but they usually cap at a small number of axes, lock color schemes, and can't handle overlaid comparison polygons cleanly.
VizForge generates a Power BI radar custom visual from a plain-English prompt. Specify the axes (your measurements), the entities (the polygons), whether to fill polygons or show outlines only, and the scale (0-100, 0-5, or raw values). Our AI writes the .pbiviz with cross-filter support, legend, and a formatting pane that controls grid rings, label angles, and fill opacity.
When to use a radar chart in Power BI
- Product scorecard vs. competitors across 8+ feature axes
- Balanced scorecard per quarter (overlay 4 polygons)
- Candidate skills profile across technical and soft dimensions
- Employee performance review on a standardized rubric
- Sports / fitness analytics — player vs. positional average
Example prompt
Example VizForge prompt
Radar chart comparing 3 products across 8 feature scores (price, reliability, support, UX, integrations, security, docs, performance). Outline only, distinct colors per product, 0-10 scale with 5-ring grid.
Data shape required
Long format: Entity (text), Axis (text), Value (numeric). Each row is one point on one polygon.
Typical DAX measures
Score Normalized =
VAR Raw = SUM( Scores[Value] )
VAR Max = CALCULATE( MAX( Scores[Value] ), ALL( Scores[Axis] ) )
RETURN DIVIDE( Raw, Max ) * 10 -- 0-10 scale
Entity Average =
CALCULATE( AVERAGE( Scores[Value] ), ALLEXCEPT( Scores, Scores[Entity] ) )Free plan: 3 visuals per month. No credit card required.
FAQ
How many axes before a radar chart becomes unreadable?
5-10 axes read clearly. Above 12, crowding starts; above 20, use parallel coordinates instead.
Can I overlay multiple entities?
Yes — each distinct Entity value draws its own polygon with a distinct color. Legend toggles visibility.
Fill or outline?
Either. Outline reads cleaner with many overlapping polygons; fill is better for showing one vs. benchmark.
Does the scale start at zero?
By default yes, which is the honest choice. Override to a minimum > 0 only if the data genuinely lives in a narrow band.
