CH-MAG-07
CH-MAG-07 . family MAG
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.
magnitudecomparison
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
