RADAR

3-6 shared-unit axes from a center; one polygon per series. Needs: 3-6 dimensions ON THE SAME SCALE for at most 2 series.

Use when

  • WARN: only when every axis shares one unit and the audience expects a radar
  • profile shapes across 3-6 same-unit dimensions, 2 series max

Do not use when

  • different units per axis (the polygon area means nothing)
  • more than 2 series (unreadable overlap)
  • any case a paired bar answers (most cases)

See instead

Alternatives

  • CH-MAG-02 (paired bars read better)
  • CH-RNK-01 (single series)

Rules

  • every axis one unit, one shared 0-based scale (validated intent)
  • polygon area is NOT a measure; the shape is the only message
  • 2 series maximum, first is the key

Never do this

  • WARN ENTRY: radars are usually the wrong answer; paired bars read faster and more honestly
  • mixed units across axes
  • 3+ series
  • reading enclosed area as a score

QA before delivering

  • axes share one unit
  • <= 2 series
  • zero-based rings
  • source present
