Params

domain

Array<DomainValue>

Explicit semantic domain. Continuous scales use [min, max]; ordinal uses ordered values.

domainMode

"grow" | "data"

Ordinal domain stability: "grow" (default) preserves assignments across filters; "data" rebuilds from current data.

range

Array<"solid" | "dashed" | "dotted" | "dotdash" | "longdash" | "twodash">

Explicit output range for the mapped aesthetic.

reverse

boolean

Reverse the scale's output direction. Default false.

naValue

"solid" | "dashed" | "dotted" | "dotdash" | "longdash" | "twodash"

Replacement for missing/null source values.

unknownValue

"solid" | "dashed" | "dotted" | "dotdash" | "longdash" | "twodash"

Replacement for invalid, out-of-domain, or unmapped values.

onExhaust

"cycle" | "error"

Ordinal palette exhaustion policy: "cycle" (default) with a warning, or "error".

guide

GuideSpec

Guide presentation override (legend, colorbar, colorsteps, or none).

Guide interaction

Legend guide for the mapped style channel. Set guide: "none" to hide.
