Weekly bars — usage

A metric by week where the bar length is honest (from zero) against a recommended band. React WeeklyBars (apps/web/src/components/sales-reports/charts/WeeklyBars.tsx), CSS coach-report.css.

When to use

• Weekly values of one coaching metric with a band and an optional team line.

When not to use

• A continuous course within one meeting — use conversation-timeline. One number against a band over weeks without bars — trend-band.

Anatomy

• Props: labels, values (null = week without data), team, band, statusOf(v), format, bandLabel, summary.
• Band zone is-max / is-min / is-both, a gradient from the recommendation edge. In band --goal-in, out --ic-amber, no goal --accent.
• First and last week labelled permanently, others on hover. A week without data is an empty slot, never 0; the team line breaks on it, a lone week is a short tick. A gap is never bridged and never drawn as a false zero.
• No data at all: do not draw an empty chart — show one quiet line („zatím bez dat“) instead.
