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
One row per category, with its name under xDataKey (name by default) and its value under the dataKey you give <Lollipop>. The chart keeps your order, so sort the rows yourself when rank matters.
import {
BarXAxis,
BarYAxis,
ChartTooltip,
Grid,
Lollipop,
LollipopChart,
} from "@/components/ui/charts";
const data = [
{ name: "Search", signups: 412 },
{ name: "Referral", signups: 318 },
{ name: "Social", signups: 196 },
{ name: "Email", signups: 154 },
{ name: "Ads", signups: 88 },
];
export const SignupsBySourceChart = () => (
<LollipopChart ariaLabel="Signups by source, October" data={data}>
<Grid horizontal />
<Lollipop dataKey="signups" label="Signups" />
<BarXAxis />
<BarYAxis />
<ChartTooltip />
</LollipopChart>
);Anatomy
<Lollipop> draws the stems, the heads and their labels. The axes, grid and tooltip are the bar chart's.
<LollipopChart data={data} xDataKey="day">
<Grid horizontal />
<Lollipop dataKey="users" label="Active users" />
<BarXAxis />
<BarYAxis />
<ChartTooltip />
</LollipopChart>LollipopChart: Gives each row a band, in the order you pass them.Grid: Guide lines across the value axis.Lollipop: The stems, the heads and, withshowValues, a label on each head.BarXAxis: The categories, or the values on a horizontal chart.BarYAxis: The values, or the categories on a horizontal chart.ChartTooltip: The hovered value. Upright charts add a crosshair, a dot and the category's label.
Horizontal, with labels
Set orientation="horizontal" and the stems run from the left, with the categories down the side. Widen margin.left to fit long names.
showValues writes each value beside its head.
Values below zero
The value axis always includes zero, so a negative value grows down from it, or left on a horizontal chart. There's nothing to configure.
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.
className goes on the chart's container, so size and spacing are utility classes.
<Lollipop> takes color, radius for the heads (6 px), strokeWidth for the stems (2 px) and stemOpacity. The stems sit at 0.45 so the heads carry the value, and the hovered stem is drawn stronger.
formatValue formats the labels, the tooltip and the value axis together. On an upright chart, give <BarYAxis> its own formatValue when the axis needs something shorter.
<Lollipop
color="var(--chart-2)"
dataKey="signups"
radius={4}
showValues
stemOpacity={0.3}
strokeWidth={1}
/>Where a part renders content of its own, you pass it in. In React:
ChartTooltip:content={({ point, index }) => …}
Loading state
With status="loading" the chart draws skeleton stems and heads on its own bands and ignores the pointer. Switch to "ready" and the real lollipops grow in.
Before there's data to pass, render <LollipopChartLoading /> in the chart's place.
Animation
Stems grow out of zero one after another over animationDuration (1100 ms), and each head pops in as its stem arrives. Value labels fade in toward the end.
Pass animate={false} to skip 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.
Stems and heads use --chart-1 unless you set color. Each head has a ring in --chart-background that keeps it clear of the grid lines.
| Token | Default | Paints |
|---|---|---|
--chart-1 | your theme's | the first series |
--chart-background | --card | dot halos, the gaps between stacked marks |
--chart-grid | --border | grid lines |
--chart-label | --muted-foreground | tick labels |
--chart-crosshair | --muted-foreground at 75% | the hover line |
--chart-date-pill-background | --primary | the date pill on hover |
--chart-tooltip-background | --popover | the tooltip panel |
:root {
--chart-background: var(--background);
--chart-grid: var(--muted);
}Accessibility
The chart is an image named by ariaLabel ("Lollipop chart" by default). Name the measure and the period there, and add ariaDescription for the takeaway.

(props: { point: Record<string, unknown>; index: number; pinned?: boolean; dismiss?: () => void }) => ReactNode
