content?(props: { point: Record<string, unknown>; index: number; pinned?: boolean; dismiss?: () => void }) => ReactNode

- Type
(props: { point: Record<string, unknown>; index: number; pinned?: boolean; dismiss?: () => void }) => ReactNode
pinnable?boolean
A click (or Enter, or Space) on the chart pins the tooltip where it is: the panel takes the pointer, so its content can grow into detail and hold controls, until another click, Escape or dismiss lets it go.

Replaces the default rows (one per series) with your own list of { color, label, value }.
