"var(--chart-crosshair)"
content?(props: { point: Record<string, unknown>; index: number; pinned?: boolean; dismiss?: () => void }) => ReactNode
Replaces the default tooltip panel body. Receives the hovered data row and its index; with pinnable, also whether the panel is pinned and a dismiss that unpins it (for a close button in a pinned panel's detail).
- Type
(props: { point: Record<string, unknown>; index: number; pinned?: boolean; dismiss?: () => void }) => ReactNode

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

- Type
string | ((point: Record<string, unknown>, line: ChartLineConfig) => string)
children?ReactNode
Extra content rendered below the rows in the default panel, for example marker details. Without it, a chart with ChartMarkers lists the markers on the hovered date there.

damping?number
Spring damping for the floating panel when matchCrosshair is off, on bklit's 0 to 100 scale: lower is bouncier, higher slower, 0 moves the panel instantly. The default, 20, is the snappy hover spring (stiffness 3600, damping 120); every other value is bklit's spring for it played six times faster.
- Default
20
indicatorDasharray?string
Dash pattern of the crosshair. Omit for a solid line.

Spring for the floating panel. Takes priority over matchCrosshair and damping.

Accepted for bklit-ui compatibility. It has no effect in bklit-tanstack-charts. Style the panel with className or the --chart-tooltip-* CSS variables instead.
backgroundColor?string
Accepted for bklit-ui compatibility. It has no effect in bklit-tanstack-charts. Set --chart-tooltip-background instead.
indicatorWidth?IndicatorWidth
Thickness of the crosshair: a width in px, or "line" (1px), "thin" (2px), "medium" (4px) or "thick" (8px).
