Properties

Property	Modifier	Type	Description
accepts?	readonly	(value) => boolean	Experimental enumerated only: also accept values this predicate approves, e.g. marker symbols registered at runtime (plan E8.11). Not serialized (plot-schema.json lists values only).
arrayOk?	readonly	boolean	Experimental Accept per-point arrays in addition to a scalar value.
clamp?	readonly	boolean	Experimental Clamp out-of-range numbers instead of falling back to dflt.
dflt?	readonly	unknown	Experimental Default value (undefined means the attribute is absent from the full output when unset).
extras?	readonly	readonly PrimitiveValue[]	Experimental Special values accepted verbatim: flaglist extras ('none'), numeric extras ('auto'), subplot-id extras ('paper', 'free').
flags?	readonly	readonly string[]	Experimental Flags for flaglist, joined with + (e.g. lines+markers).
freeLength?	readonly	boolean	Experimental Allow info_array to be shorter/longer than items.
items?	readonly	| AttrSpec<unknown, unknown> | readonly AttrSpec<unknown, unknown>[]	Experimental Item specs for info_array: one spec for every item, or one per position.
max?	readonly	number	Experimental
min?	readonly	number	Experimental Inclusive bounds for number, integer and info_array items.
noBlank?	readonly	boolean	Experimental Reject empty strings (string).
strict?	readonly	boolean	Experimental Reject non-string values instead of stringifying numbers (string).
values?	readonly	readonly PrimitiveValue[]	Experimental Allowed values for enumerated.
