Patient vitals, one reference range

The normal band is declared once and drawn in all twelve panels, so the question "who is outside the range" is answered by looking, and P-07's tachycardia is unmissable. Hover anywhere: one card reads every patient at the same hour.

A trellis-scoped annotation is declared once on the host and projected into every panel through each panel's own scale, so twelve hand-annotated charts collapse into one annotations.yaxis entry. An annotation with scope: 'P-07' draws only in that patient's panel (the medication event). trellis.tooltip: 'grid' composes ONE tooltip card with one row per panel at the hovered hour, honoring the y formatter, and works even on panels a virtualized grid has not mounted. Trellis is a premium feature; without a license it renders with a trial watermark.
