resolveGroupValues

resolveGroupValues(spec, result?, name?): any[]

Defined in: ds/src/plot/utils.js:26

Normalize a colorBy (or labels) specification into a plain array of per-observation values.

Accepted forms:

• an array (used as-is)
• any iterable, e.g. an Arquero column or a typed array (converted)
• a { data, column } descriptor (column extracted from table-like data)
• a column-name string, resolved against the source rows the model kept from a declarative fit (e.g. pca.fit({ data, columns }) stores the naOmit-filtered rows so values stay aligned with the scores)

Parameters

spec

any

colorBy specification

result?

any = null

Fitted model (for string column lookup)

name?

string = 'colorBy'

Option name used in error messages

Returns

any[]

Array of values, or null when spec is null
