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
Each row is one period: a Date under date and its open, high, low and close. A candle that closed at or above its open counts as up.

);Anatomy
One Candlestick draws every row. The grid, the axes and the tooltip are the same parts the line chart uses.
<CandlestickChart data={data}>
<Grid horizontal />
<Candlestick />
<XAxis />
<YAxis />
<ChartTooltip />
</CandlestickChart>CandlestickChart: Holds the rows, spaces the candles and fits the price axis to the wicks.Grid: Guide lines behind the candles.Candlestick: The candles: a body from open to close and a wick from low to high.XAxis: Date labels along the bottom.YAxis: Price labels.ChartTooltip: The crosshair, the date pill and the hovered candle's prices.
Up and down colors
Rising candles use --chart-positive and falling ones --chart-negative. Pass positiveFill and negativeFill for your own, a token or a url(#id) gradient defined inside the chart.
Candles size themselves to the spacing, leaving a candleGap of 20% of each slot. candleWidth={18} fixes them at 18 px instead.
Zooming to a range
Pass xDomain as a start and end date and the chart plots only the candles inside it, with the price axis refitted to them. Buttons or a select that set it make a range picker.
The example also passes xDomainSlotCount, the number of days in view, so the first and last candles keep half a slot of room at the edges.
Hover
While a candle is hovered the others fade to fadedOpacity (0.3). Set showHoverFade={false} to keep them at full strength.
showDots={false} on the tooltip drops the dot on the close, leaving the crosshair and the date pill.
Patterned bodies
bodyPatternPositive and bodyPatternNegative lay a pattern over the bodies. Define a pattern inside the chart with an id, as the example does with PatternLines, and pass url(#id). insideStrokeWidth frames each body in its own color so the stripes keep an edge.
Candles only
Leave out the Grid and the YAxis for a chart that's only candles and dates. A style height, such as style={{ height: 320 }}, replaces the 2:1 aspect ratio when the chart sits in a fixed slot.
With volume
For volume under the price, or a moving average over it, put a Candlestick in a ComposedChart. There it draws on its own scale, which fits the wicks while the volume bars keep a zero baseline.
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.
Without rows, the panel shows the close alone. Pass rows to list all four prices, formatted the way your market quotes them.
On this chart indicatorColor can also be a function of the hovered row, which is how the crosshair turns green or red with the candle under it.
<ChartTooltip
indicatorColor={(point) =>
Number(point.close) >= Number(point.open)
? "var(--chart-positive)"
: "var(--chart-negative)"}
rows={(point) => [
{ color: "var(--chart-1)", label: "Open", value: Number(point.open).toFixed(2) },
{ color: "var(--chart-1)", label: "High", value: Number(point.high).toFixed(2) },
{ color: "var(--chart-1)", label: "Low", value: Number(point.low).toFixed(2) },
{ color: "var(--chart-1)", label: "Close", value: Number(point.close).toFixed(2) },
]}
/>Where a part renders content of its own, you pass it in. In Solid:
ChartTooltip:content={({ point, index }) => …}
Loading state
The candlestick chart has no loading state. While the prices load, a <BarChartLoading /> with the same aspectRatio holds the space and reads close enough to a row of candles.
Animation
Candles grow out from their middle, body and wick together, one after another from the left, within animationDuration (1100 ms). enterTransition takes a spring or a tween with its duration in seconds.
animate={false} on the Candlestick draws them in place. Reduced motion skips the entrance.
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.
--chart-positive is a fixed green and --chart-negative follows your --destructive. Override either in your CSS to recolor every candlestick, or set the fills per chart.
| Token | Default | Paints |
|---|---|---|
--chart-positive | a fixed green | values above the baseline in profit and loss |
--chart-negative | --destructive | values below the baseline in profit and loss |
--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 ("Candlestick chart" by default). Name the symbol and the period there.
The tooltip is a polite live region. Here its text is the candle's date and four prices, so a screen reader hears them as the focus moves.
- Tab
- Moves focus to the chart.
- Arrow Right
- Moves to the next candle. ArrowDown does the same.
- Arrow Left
- Moves to the previous candle. ArrowUp does the same.
- Home
- Jumps to the first candle.
- End
- Jumps to the last candle.
API reference
Solid takes the same props as React, with class for className. A render prop is a function, called again when its arguments change, so destructured parameters stay current.

"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 }.

- 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.
class?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

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).

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

- Default
"line"
