Scrubbing

scrub

<LiveChart data={data} value={value} scrub /> // default true
<LiveChart data={data} value={value} scrub={false} />

When enabled, hovering shows a crosshair with time and value tooltips. The tip lerps toward the scrub target so motion stays soft.

Prop	Default	Role
`tooltipY`	`14`	Vertical offset for the tooltip stack
`tooltipOutline`	`true`	Outline / border on tooltip chrome
`formatTime`	`HH:MM:SS`	Formats unix seconds for the time label
`formatValue`	`v.toFixed(2)`	Formats the value label
`cursor`	`"crosshair"`	CSS cursor on the chart surface
`onHover`	—	`(point: HoverPoint \| null) => void`

type HoverPoint = {
  time: number;
  value: number;
  x: number;
  y: number;
};

onHover(null) fires when the pointer leaves.

With a11y (default on) and scrub, the plot is focusable and Arrow/Home/End/Escape scrub from the keyboard. See Accessibility.

In multi-series mode the crosshair can surface multiple values at the scrub time. Series visibility still respects toggle chips.

Set scrub={false} and optionally cursor="default" when the chart is decorative or covered by another interaction layer.
