About

Use it for a short list of distinct things (browsers, plans, teams) where each keeps its color across the page, such as a pie of the same data nearby. For one series over time, a single color reads calmer.

Five bars run to the right with 5px corners, Chrome down to Other, each in one of the five chart colors and named beside it. There's no value axis or grid; the tooltip gives the visitor count.

Usage

import { ChartBarMixed } from "@/components/charts/chart-bar-mixed";
<ChartBarMixed />

Customize

  • The rows are { browser, fill, visitors }. barX puts visitors on a linear x scale with axis: false and browser on a band y scale.
  • Each row's fill points at its browser's chartConfig color, read by fill: (datum) => datum.fill: chrome is var(--chart-1), safari var(--chart-2), through other at var(--chart-5).
  • chartConfig.visitors only has a label, for the value's name; the five browser entries hold the colors.
  • The y axis tick format turns each browser key into its display name, and radius: 5 rounds the bars.

FAQ

How does each bar get its own color?

Each browser has an entry in chartConfig with a --chart-N color, each row a fill that points at it (var(--color-chrome)), and the mark paints with fill: (datum) => datum.fill. Change a browser's color to recolor its bar.

What if I have more than five categories?

The theme has five chart colors, --chart-1 to --chart-5. Add tokens of your own, or give the extra entries any CSS color. Past seven or eight, one color with sorted bars reads better.

Can a pie chart use the same colors?

Yes. The pie charts use the same browsers with the same chartConfig colors. Share one config object between both charts and each browser keeps its color.

Where do the browser names come from?

From the y axis: its tick format looks each browser key up in chartConfig and prints its label. Change the labels to rename them.

Do I need a legend?

Not here: each bar has its name beside it, so a legend would repeat the axis. Add one when the axis is hidden or a color shows up in more than one place.

API Reference

children?ReactNode

What sits under the chart inside the container: a ChartLegend.

tooltip?ChartTooltipContentProps | false

ChartTooltipContent's props (indicator, hideLabel, formatter…) for the default body, or false for TanStack's own tooltip body.

Type
ChartTooltipContentProps | false
renderTooltip?(context: ChartTooltipBodyRenderContext) => ReactNode

A whole tooltip body of your own, in place of ChartTooltipContent: it gets the focused points (each with its datum, group and color).

Type
(context: ChartTooltipBodyRenderContext) => ReactNode
defaultIndex?number

The category whose tooltip shows before any pointer, as Recharts' defaultIndex.

height?number

A fixed height in pixels for the chart, in place of the container's.

aspectRatio?number

A width-to-height ratio for the chart, in place of the container's height.

initialWidth?number

The width the chart renders at before it's measured.

onFocusChange?(point: ChartPoint | null) => void

Called as the focused point changes: a pointer, a key or a tap.

Type
(point: ChartPoint | null) => void
onFocusGroupChange?(points: readonly ChartPoint[]) => void

Called with every point at the focused category (a stacked or grouped chart's).

Type
(points: readonly ChartPoint[]) => void
onSelect?(point: ChartPoint | null) => void

Called when a point is clicked or picked with Enter.

Type
(point: ChartPoint | null) => void
CSS variableType

Each config key's color (its theme color in light and dark), set on the container: the marks paint with var(--color-<key>).

ChartTooltipContent

<div>

labelKey?string

The datum field (or config key) the label is read from, looked up in config.

nameKey?string

The datum field (or config key) each row's series is read from: a pie's browser.

valueKey?string

color?string

One indicator color for every row, in place of each series' own.

labelFormatter?(label: string, points: readonly ChartPoint[]) => string

Formats the label (the config's label or the category), with the rows' points: a date written out, a unit.

(label: string, points: readonly ChartPoint[]) => string
formatter?(value: number | string, name: string, item: ChartTooltipItem, index: number) => ReactNode

(value: number | string, name: string, item: ChartTooltipItem, index: number) => ReactNode
className?string

Classes for the tooltip's card.

ChartLegend

<div>

PropType
config?ChartConfig

The series to list: the container's config by default.

keys?readonly string[]

A color for each theme, in place of color.

Helpers

ExportType
chartTooltip?(settings?: ChartTooltipSettings) => ChartDefinitionOptions

defineChart's second argument for a chart with a tooltip: what a pointer or a key focuses (group-x, each category's series, by default), the focus ring, and the host ChartContainer draws its body in.

Type
(settings?: ChartTooltipSettings) => ChartDefinitionOptions
chartTheme?ChartTheme

defineChart's theme in the site's tokens: the text, the grid and the palette (--chart-1 to --chart-5).

chartColors?(config: ChartConfig, keys?: readonly string[]) => { domain: string[]; range: string[] }

defineChart's color: each series key (in config order, or keys') painted var(--color-<key>), for marks with a color channel.

Type
(config: ChartConfig, keys?: readonly string[]) => { domain: string[]; range: string[] }
chartLinearScale?() => LinearScale

A value axis drawn as Recharts draws its default one: zero in the domain, five nice ticks. Pass it as a factory: y: { scale: chartLinearScale }.

Type

curveNatural?CurveFactory

curveStep?CurveFactory

D3's step curve, for a line or area that holds each value: curve: d3Curve(curveStep).

curveMonotoneX?CurveFactory

D3's monotone curve, smooth without overshooting a point: curve: d3Curve(curveMonotoneX).
