LiveLineChart
dataLiveLinePoint[]

The latest value. The chart eases its display toward it.
dataKey?string
Key used for the value field.

"value"
window?number
Visible time window in seconds.
- Default
30
numXTicks?number
Number of x axis labels; also sizes the leading offset.

5
nowOffsetUnits?number
Leading offset in x tick units. 0 puts "now" at the right edge.

0
exaggerate?boolean
Use a tight y range around the data instead of the default padded one.
- Default
false
lerpSpeed?number
How fast the displayed value and y range ease toward their targets (0 to 1).
- Default
0.08
margin?Partial<ChartMargin>
Space around the plot area in pixels. Missing sides use the default.

{ top: 24, right: 16, bottom: 32, left: 16 }
paused?boolean
Freeze the scrolling.
- Default
false
childrenReactNode
The layers to draw: LiveLine, Grid (its horizontal rows; vertical columns are not drawn), LiveXAxis, LiveYAxis, ChartTooltip.
className?string
Extra CSS class name for the chart container.
style?CSSProperties
Inline styles for the chart container. Set height to size the chart.
ariaLabel?string

- Default
2
curve?CurveFactory
Accepted for bklit-ui compatibility and ignored: the line is always bklit's default curveMonotoneX. Native rolling refuses a custom curve path (custom-path, dist/motion-path.js:16), so the curve is sampled into rows (smoothRows in definition.ts) and another factory cannot be swapped in.
fill?boolean
Show the gradient fill under the line.
- Default
true

Show the pulsing live dot at the right edge.
- Default
true
dotSize?number
Radius of the live dot in px.

Show a dot on every series at the hovered position.

"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.

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).

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

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.

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