# getGroupMeta

Exported by `@workspace/active-charts`. Generated from the package source; part of [the index of every export](/packages/active-charts/all-exports).

## Functions, hooks and constants

**getGroupMeta**: `(point: ChartDatum) => GroupMeta \| undefined`

Type-guard accessor for the `GroupMeta` payload attached by
`aggregateByGroup`. Returns `undefined` for ungrouped points so callers
never need to read the sentinel key directly.
