shadcn.io is an independent project built on shadcn/ui
Installation
The command adds the example above to components/charts/ and, the first time, the chart kit to components/ui/charts/. Both are source files in your project from then on: read them, change them, delete what you don't use.
Usage
The x axis is time: each row has a Date under date and a number for each Scatter. To plot two measures against each other instead, use the density chart's points.
<script setup lang="ts">
import {
ChartTooltip,
Grid,
Scatter,
ScatterChart,
XAxis,
YAxis,
} from "@/components/ui/charts";
const data = [
{ date: new Date(2026, 9, 5), orders: 132 },
{ date: new Date(2026, 9, 6), orders: 158 },
{ date: new Date(2026, 9, 7), orders: 141 },
{ date: new Date(2026, 9, 8), orders: 176 },
{ date: new Date(2026, 9, 9), orders: 169 },
];
</script>
<template>
<ScatterChart ariaLabel="Orders per day" :data="data">
<Grid horizontal />
<Scatter data-key="orders" fill="var(--chart-2)" label="Orders" />
<XAxis />
<YAxis />
<ChartTooltip />
</ScatterChart>
</template>Anatomy
A Scatter per series, over the same grid, axes and tooltip as the line chart.
<ScatterChart :data="data">
<Grid horizontal />
<Scatter data-key="organic" fill="var(--chart-1)" label="Organic" />
<Scatter data-key="referral" fill="var(--chart-2)" label="Referral" />
<XAxis />
<YAxis />
<ChartTooltip />
</ScatterChart>ScatterChart: Holds the rows and the date axis, and runs the hover.Grid: Guide lines behind the dots.Scatter: One series of dots, read fromdataKey, with optional rings.XAxis: Date labels along the bottom.YAxis: Value labels.ChartTooltip: The hovered date's values, the crosshair and the date pill.
Hover
While a date is hovered, its dots grow and every other dot drops to inactiveOpacity (0.3). inactiveMode="blur" also blurs them, by inactiveBlur pixels. Set :fadeOnHover="false" to leave them alone.
Rings and outlines
Rings are off by default. strokeWidth draws one around each dot, ringGap pixels out (2), and radius sets the dot itself (5).
outlineWidth adds a thin outline outside the ring, in outlineColor.
Strip plots
When many rows share a date, their dots pile into one. jitter spreads them sideways by seeded offsets, so they land in the same place on every render. true spreads them over 35% of the smallest gap between dates, and { x, y, seed } sets that share, a vertical spread in pixels and the pattern.
With jitter on, hover picks the nearest dot rather than a whole date, and the crosshair is hidden unless you set showCrosshair. formatXLabel relabels the axis, for example with month names.
Dense data
Leave the rings off and drop radius to 3 or 4, and two months of daily readings read as one cloud with its outliers clear of it.
Thousands of dots
Each dot is an SVG element, which gets slow past about 2,000 dots. Pass :renderer="canvasRenderer" to each <Scatter> and the dots paint on one canvas, with hover, the crosshair and the tooltip as before.
On a canvas the dots appear with the chart's reveal in one sweep and dim together on hover.
Customization
The kit is in your project, in components/ui/charts/: your framework's components over a shared core/. Change a default there and every chart picks it up.
class goes on the chart's container, so size and spacing are utility classes.
content doesn't have to start from scratch. Return the kit's TooltipContent with your own title and rows and the panel keeps its usual look.
<ChartTooltip>
<template #content="{ point }">
<TooltipContent
:rows="[
{ color: 'var(--chart-3)', label: 'p95', value: `${point.latency} ms` },
]"
:title="String(point.release)"
/>
</template>
</ChartTooltip>Where a part renders content of its own, you pass it in. In Vue:
ChartTooltip:<template #content="{ point, index }">
Loading state
The scatter chart has no loading state. Hold its place with a Skeleton at the same aspect ratio until the rows arrive.
Animation
Dots fade in from a slight blur, left to right, so the series is fully drawn after animationDuration (1100 ms). enterBlur sets the starting blur in pixels (2).
:animate="false" on a Scatter shows its dots at once. Change revealSignature to replay the entrance. Reduced motion skips it.
Theming
Every color in the kit is one of your theme's tokens or a mix of them, except --chart-positive, a fixed green. A preset or the .dark class restyles the chart, and overriding a token in your CSS changes it everywhere.
Give each Scatter a fill. Its ring follows the fill unless you set stroke. A series without either takes the next color from your chart palette.
| Token | Default | Paints |
|---|---|---|
--chart-1 | your theme's | the first series |
--chart-2 | your theme's | the second series |
--chart-3 | your theme's | the third series |
--chart-grid | --border | grid lines |
--chart-label | --muted-foreground | tick labels |
--chart-crosshair | --muted-foreground at 75% | the hover line |
--chart-tooltip-background | --popover | the tooltip panel |
--chart-date-pill-background | --primary | the date pill on hover |
:root {
--chart-grid: var(--muted);
--chart-label: var(--foreground);
}Accessibility
The chart is announced as an image named by ariaLabel ("Scatter chart" by default). If the point is a cluster or an outlier, say so in ariaDescription.
- Tab
- Moves focus to the chart.
- Arrow Right
- Moves to the next date. ArrowDown does the same.
- Arrow Left
- Moves to the previous date. ArrowUp does the same.
- Home
- Jumps to the first date.
- End
- Jumps to the last date.
API reference
Vue takes the same props as React, in camelCase or kebab-case, with class for className. Render props are scoped slots (#content), and callbacks such as onHoverChange can be written as listeners (@hover-change).
ScatterChart
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"
class?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.

"var(--chart-crosshair)"
#content?slot: { point, index }

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 }.
