tcviz VISUALS TO POWER BI

Radar & Spider Chart by TCViz

A radar chart for Power BI that reads honestly: a fixed scale from zero, axes that stay put, gaps for empty values.
From “who is better?” to better at what, and against which target in three fields.

Use cases
Supplier evaluation
Team skills
Product comparison
Surveys
Maturity models
KPIs vs target

Player profiles
Shift your mindset: A radar that rescales with every filter makes 57 look like 100. Fix the scale and the shapes start telling the truth.

Three fields

Axis (the criteria), Values (the score, as Average) and Series (what you compare).

  • Setup guide in the corner
  • Hierarchy in Axis: drilldown
  • Measures as axes, no unpivot
  • The measure's own number format

1–2 min

A scale that does not move

From zero by default, or fixed: 1 to 5, 0 to 100. Axes keep their order when you filter.

blank = gap in the outline  |  never drawn as zero
  • Note on a dominant axis
  • Values outside a fixed scale

Measure against a target

A Target field draws a dashed shape and the gap on every axis, green or red.

Different units, one radar

Scale per axis: each axis its own range and rings. Lower is better: price, days, ppm reversed.

  • Bands and a reference ring
  • Axis groups as named arcs
  • Annotations from a measure
  • Value table under the chart

Templates Clean, Classic, Minimal, Contrast, Compact, IBCS style — then adjust anything; your settings win.

  • Curved lines that stay honest
  • Marker shape per series
  • Polygon or circle, rotation
  • Format on the canvas

Avoid common mistakes

  • Score summed instead of averaged
  • Reading the area as a total
  • Eight shapes on one radar
  • Average, fixed scale, small multiples
  • One radar per series (Pro) for many items

Not only “who scores higher” — where each one falls short, and by how much.
Key benefits
A scale you can trust
Power BI has no built-in radar; this one starts at zero and does not move.
Gaps you can act on
The difference to target on every axis, in green or red.
Native Power BI interactions
Click a point, an axis or a series to filter; bookmarks keep the selection.
Private by design
No network requests: everything is computed inside your report.
Key takeaways
Scores go in Values as Average, never Sum.
Survey questions in columns: leave Axis empty, each measure is an axis.
Conditional formatting (fx) on markers works without a Series field.
Pro features are drawn on your data under a “Pro preview” watermark while you edit.
Keyboard: arrows move point to point, Enter selects.
Pro from 0.99 USD a month.More series, targets, scale per axis, small multiples.
