Params

domain

Array<DomainValue>

Explicit semantic domain. Manual/ordinal scales use ordered values; sequential/binned scales use [min, max].

breaks

Array<number | string>

Explicit semantic reference ticks for sequential colorbars or ordered boundaries for binned colorsteps.

reverse

boolean

Reverse the output color range. Default false.

transform

"identity" | "log10" | "sqrt"

Pre-training quantitative transform for sequential/binned color values. log10/sqrt require non-temporal values; ordinal, manual, and identity families do not accept a transform.

oob

"censor" | "squish"

Out-of-bounds policy for an explicit continuous/binned domain: "censor" (default) or "squish".

naValue

string

Color for null/missing values. Default9.

unknownValue

string

Color for invalid, out-of-domain, or unmapped values. Default9.

labels

string

Guide label format: numeric (".1f", ",d", ".0%") or temporal strftime-style text.

guide

GuideSpec

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

low

string

Low-end #rgb/#rrggbb color.

high

string

High-end #rgb/#rrggbb color.

Guide interaction

Colorsteps guide by default for binned color. Use guide helpers or guide: "none" to suppress.
