Radar Chart

A vendor scorecard with price in dollars, delivery in days and satisfaction as a percentage cannot share one axis scale. Per-axis normalization rescales each dimension before drawing: min-max for a plain 0 to 100 view, percentile rank when you want to know where each entity sits among its peers, or z-score when the spread matters. Percentile mode clamps at the fifth and ninety-fifth percentile so a single outlier does not flatten everyone else.

Axes where lower is better, such as price or error rate, are marked as inverted, so further out always means better. The real values stay in the tooltips and labels, so nobody has to guess what a normalized 72 was in dollars.

Map a Target field and every series is judged against a dashed goal polygon. Red, amber and green zone bands turn the chart into a maturity or risk scorecard, drawn only where the scale makes them honest. A benchmark band shows the envelope or average of the visible series as instant context, and conditional formatting colours whole series by a rule on their average, minimum, maximum or total.

Six overlapping polygons are a spaghetti plot, whatever the colours. Hovering a legend entry isolates one series and dims the rest, which is often enough. When it is not, one dropdown switches the same fields into pizza slices with value chips, the football-scouting look, into radial columns, or into lollipops.

Small multiples draw one mini radar per series on a shared scale, each carrying the dashed average silhouette of the field, so a page of eight profiles reads at a glance and still lets you spot who is above average where.

The free tier renders up to three series on up to 100 axes, every cosmetic option and the shared-scale controls. That covers a single-entity profile and simple comparisons. Comparing many entities, which is the core purpose of a radar chart, needs the premium licence, as do per-axis scaling, normalization, inverted axes, targets, zones, benchmarks, the reference line, conditional formatting, chart modes and small multiples.

An unlicensed viewer still sees the first three series plus the standard Power BI licence banner, never a broken visual, and every premium feature previews free while you edit the report.
