radar

Use for named spokes with a non-negative score (y ≥ 0). Keep spoke order. Optional series draws one polygon per series on one scale (max if it is at least the data max, otherwise max(y) or 1). A max below the data expands the scale so a spoke is not clipped. A missing spoke is a gap. A grouped bar is clearer when the reader needs the exact number. Negatives fail with E_NEGATIVE_VALUE.

Do not use for a single linear comparison (bar) or a time series (line).

x spoke · y number ≥ 0 · series optional

Rules. Keep order. One scale for every series: max if set and at least the data max, otherwise max(y) or 1. A missing spoke is a gap. Negatives → E_NEGATIVE_VALUE. A grouped bar is clearer when the reader needs the exact number.
