Type Alias: ColumnHistogram

ColumnHistogram = Histogram & object | { kind: "categorical"; otherCount: number; values: readonly object[]; }

Defined in: graphty-element/src/session/types.ts:581

How one data column's values are distributed: what session.data.histogram(column) returns.

A column that measures amounts (measurement: "quantitative") is binned like a run's field, with kind: "numeric" beside the Histogram fields. Any other column is counted by value, with kind: "categorical".

OPEN UNION: kinds may be added in a minor release; handle unknown kinds.
