Interface: BarMeasure ​

Defined in: tools/src/drawings.ts:200

A segment from a to b that reports how many bars lie between them — the pane's nearest bar at each end, counted by index in the data. The x mapping can't answer this: under a continuous mapping its domain is time, and time between two bars is not a bar count.

style? ​

optional style?: Partial<LineStyle>

Defined in: tools/src/drawings.ts:85

Per-drawing override — the third layer of the same resolution the toolbox already does (theme variables → toolbox override → this). The same Partial<LineStyle> shape, deliberately: one leaf vocabulary (width·color·dashArray), not a second one.

The values are literals, not theme tokens — a canvas can't read var(), and this is a saved value. A drawing colored by hand keeps its color across a theme switch; absent means "the theme's".
