API Reference

ScatterChart

PropType
datareadonly Row[]

The rows to plot. Each row holds the x value under xDataKey and one number per Scatter series under that series' dataKey.

xDataKey?string

Key of the x value in each row. The value must be a Date (or something new Date() accepts, such as a timestamp).

Default
"date"
animationDuration?number

Duration of the entrance reveal in milliseconds. 0 skips the animation. enterTransition.duration overrides it.

Default
1100
margin?Partial<ChartMargin>

Space around the plot area in pixels. Missing sides use the default.

Type
Partial<ChartMargin>
Default
{ top: 40, right: 40, bottom: 40, left: 40 }
aspectRatio?string

CSS aspect ratio of the chart ("width / height" or a number), applied to the container width.

Default
"2 / 1"
className?string

Extra CSS class name for the chart container.

style?CSSProperties

Inline styles for the chart container.

onPhaseChange?(phase: ScatterChartPhase) => void

Called with "revealing" when the entrance starts and "ready" when the chart becomes interactive.

Type
(phase: ScatterChartPhase) => void
animationEasing?string

CSS easing for the per-point entrance, for example "cubic-bezier(0.85, 0, 0.15, 1)". When unset, enterTransition.ease or the default reveal easing is used.

enterTransition?{ readonly duration?: number; readonly ease?: unknown }

Entrance timing: duration (in seconds) sets the length of the reveal and ease (a four-number cubic bezier) the easing.

Type
{ readonly duration?: number; readonly ease?: unknown }
revealSignature?string

Changing this string replays the entrance animation.

jitter?ScatterJitter

Spreads points that share an x value into a strip plot, by seeded offsets that never move between renders. Hover then snaps to the nearest point, the tooltip shows its real values, and ChartTooltip hides its crosshair unless showCrosshair is set. true spreads 0.35 of the band step; see ScatterJitter for the other forms.

formatXLabel?(date: Date) => string

Formats the x-axis ticks and the date pill, for example short month names for monthly data (the tooltip keeps its weekday date). XAxis's formatValue still wins on the axis. Defaults to "Jan 1" style labels.

Type
(date: Date) => string
childrenReactNode

labels?readonly string[]

The tick text of each data row, in row order: it replaces the date formatting (pair it with ChartTooltip dateLabels).

tickerHalfWidth?number

Half-width in px of the zone around the date pill inside which tick labels are hidden. Line, area and composed charts widen it to the pill's half-width plus the widest tick label's, so no label sits half under the pill.

Default
true

Type
(value: number) => string

ChartTooltip

PropType
showDatePill?boolean

Show the date pill that rides along the bottom of the plot.

dotVariant?"dot" | "ring"

Dot style: a filled "dot" or a transparent "ring" square. Read by BarChart only.

Type
"dot" | "ring"
Default
"dot"

indicatorColor?string | ((point: Record<string, unknown>) => string)

Color of the crosshair. Only a string is applied; the function form that bklit-ui accepts is ignored and the default is used.

Type
string | ((point: Record<string, unknown>) => string)
Default
"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
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.

Default
false
rows?(point: Record<string, unknown>) => { readonly color: string; readonly label: string; readonly value: string | number }[]

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

(point: Record<string, unknown>) => { readonly color: string; readonly label: string; readonly value: string | number }[]
dotColor?string | ((point: Record<string, unknown>, line: ChartLineConfig) => string)

Fill of the tooltip dots. A function receives the hovered row and the series config, and is called again each time the hovered row changes. Defaults to each series' color; a ProfitLossLine's dot takes the color of the hovered value's sign.

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.

className?string

Extra class name for the tooltip panel.

springConfig?SpringConfig

Spring for the floating panel when matchCrosshair is on. Defaults to the chart's tooltip spring.

matchCrosshair?boolean

Make the floating panel follow the pointer with the same spring as the crosshair instead of damping.

Default
false
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.

indicatorFadeEdges?IndicatorFadeEdges

Vertical fade of the crosshair: both ends, the top, the bottom, or none (solid).

Default
"both"
indicatorFadeLength?number

Size of the crosshair's fade, as a percentage of its height (2 to 40).

Default
10
indicatorEndColor?string

Bottom colour of the crosshair: it ramps from indicatorColor at the top to this at the bottom (composes with the fade).

indicatorEnd?"plot" | "point"

How far down the crosshair reaches: the whole plot, or down to the hovered point of the first series.

Type
"plot" | "point"
Default
"plot"
dotHaloBlur?number

Blur in px on the dots' halo, for a soft glow.

Default
0
topOffset?number

Extra gap in px between the top of the plot and the tooltip panel.

Default
0
dateLabels?readonly string[]

The date pill's text for each data row, in row order (pair it with XAxis labels).

boxSpringConfig?SpringConfig

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

panelStyle?CSSProperties

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).

Default
"line"
columnWidth?number

Accepted for bklit-ui compatibility. It has no effect in bklit-tanstack-charts.
