Documentation / @finchart/tools / ParallelChannel

Interface: ParallelChannel

Defined in: tools/src/drawings.ts:214

Two parallel lines: a–b, and a second line through c with the same price-per-x slope, over the same x span. "Parallel" is a price-space statement — on a log axis the two are not parallel on screen, deliberately, so the saved bytes mean the same thing under every scale. c is an absolute anchor (its distance from the first line is derived, never stored).

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".
