Installation

pnpm dlx shadcn@latest add @kibo-ui/contribution-graph

Requires @kibo-ui in the registries of your components.json (shadcn adds official directory namespaces automatically).

Usage

usage.tsx
import { ContributionGraph, ContributionGraphBlock, ContributionGraphCalendar, ContributionGraphFooter, ContributionGraphLegend, ContributionGraphTotalCount, type Activity } from "@/components/kibo-ui/contribution-graph";const data: Activity[] = [  { date: "2024-01-01", count: 2, level: 1 },  { date: "2024-01-02", count: 8, level: 3 },  { date: "2024-01-03", count: 0, level: 0 },];export function Example() {  return (    <ContributionGraph data={data}>      <ContributionGraphCalendar>        {(props) => <ContributionGraphBlock {...props} activity={props.activity} />}      </ContributionGraphCalendar>      <ContributionGraphFooter>        <ContributionGraphTotalCount />        <ContributionGraphLegend />      </ContributionGraphFooter>    </ContributionGraph>  );}
  • 展示 GitHub 风格的年度活动、提交、签到或使用量历史。
  • 需要按周和星期几组织的离散活动热力图。
  • 需要自定义块大小、间距、圆角、标签文本或周起始日的仪表板。
  • 需要通过 render-prop 子组件定制单元格、总数文本或图例。

Examples

Custom week start and sizing

Use Monday as the first day of the week and adjust the visual density for a dashboard card.

custom-week-start-and-sizing.tsx
import { ContributionGraph, ContributionGraphBlock, ContributionGraphCalendar } from "@/components/kibo-ui/contribution-graph";export function WeeklyActivity({ data }: { data: { date: string; count: number; level: number }[] }) {  return (    <ContributionGraph data={data} blockSize={10} blockMargin={3} weekStart={1}>      <ContributionGraphCalendar>        {({ activity, dayIndex, weekIndex }) => (          <ContributionGraphBlock            activity={activity}            dayIndex={dayIndex}            weekIndex={weekIndex}          />        )}      </ContributionGraphCalendar>    </ContributionGraph>  );}

Localized labels and total count

Provide custom month, weekday, total-count, and legend labels for a localized interface.

localized-labels-and-total-count.tsx
import { ContributionGraph, ContributionGraphBlock, ContributionGraphCalendar, ContributionGraphFooter, ContributionGraphLegend, ContributionGraphTotalCount } from "@/components/kibo-ui/contribution-graph";export function LocalizedGraph({ data }: { data: { date: string; count: number; level: number }[] }) {  return (    <ContributionGraph      data={data}      labels={{        months: ["1月", "2月", "3月", "4月", "5月", "6月", "7月", "8月", "9月", "10月", "11月", "12月"],        weekdays: ["日", "月", "火", "水", "木", "金", "土"],        totalCount: "{{year}}年の活動数: {{count}}",        legend: { less: "少ない", more: "多い" },      }}    >      <ContributionGraphCalendar>        {(props) => <ContributionGraphBlock {...props} activity={props.activity} />}      </ContributionGraphCalendar>      <ContributionGraphFooter>        <ContributionGraphTotalCount />        <ContributionGraphLegend />      </ContributionGraphFooter>    </ContributionGraph>  );}

Custom block rendering

Use the calendar render prop to add SVG attributes or custom classes to individual activity blocks.

custom-block-rendering.tsx
import { ContributionGraph, ContributionGraphBlock, ContributionGraphCalendar } from "@/components/kibo-ui/contribution-graph";export function AccessibleActivityGraph({ data }: { data: { date: string; count: number; level: number }[] }) {  return (    <ContributionGraph data={data} maxLevel={4}>      <ContributionGraphCalendar>        {({ activity, dayIndex, weekIndex }) => (          <ContributionGraphBlock            activity={activity}            dayIndex={dayIndex}            weekIndex={weekIndex}            aria-label={`${activity.count} activities on ${activity.date}`}            className="transition-opacity hover:opacity-80"          />        )}      </ContributionGraphCalendar>    </ContributionGraph>  );}

API reference

PropTypeDefaultDescription
ContributionGraph.dataActivity[]nullActivity records to render. Each record requires date, count, and level; an empty array causes the graph to render null.

ContributionGraph.blockRadiusnumber2SVG corner radius for activity blocks.
ContributionGraph.blockSizenumber12Width and height of each activity block in pixels.
ContributionGraph.fontSizenumber14Font size used by the graph and its calculated labels.
ContributionGraph.labelsLabelsundefinedOptional label configuration. Supports months, weekdays, totalCount, and legend.less/more.
ContributionGraph.maxLevelnumber4Maximum valid activity level and number of legend levels. The effective value is at least 1.
ContributionGraph.styleCSSProperties{}Inline styles applied to the root div; the component's fontSize is set first and can be overridden by this object.
ContributionGraph.totalCountnumberundefinedExplicit total used by ContributionGraphTotalCount. When omitted, counts are summed from data.
ContributionGraph.weekStartdate-fns Day0First weekday used to group the calendar, where 0 is Sunday and 1 is Monday.

ContributionGraph.classNamestringundefinedAdditional classes for the root div.
ContributionGraph HTML attributesHTMLAttributes<HTMLDivElement>nullOther standard div attributes are accepted and forwarded to the root element.
ContributionGraphBlock.activityActivitynullActivity record represented by this SVG rect. Its level must be between 0 and maxLevel or a RangeError is thrown.

Labels.monthsstring[]DEFAULT_MONTH_LABELSMonth labels indexed from January through December.
Labels.weekdaysstring[]["Sun", "Mon", "Tue", "Wed", "Thu", "Fri", "Sat"]Configured weekday labels. The current source stores these labels but does not render them.
Labels.totalCountstring"{{count}} activities in {{year}}"Template for the default total-count text; the first {{count}} and {{year}} tokens are replaced.
Labels.legend.lessstring"Less"Text shown before the legend levels.
Labels.legend.morestring"More"Text shown after the legend levels.

Accessibility

  • The calendar renders an SVG title of “Contribution Graph,” but individual blocks do not receive accessible names by default.
  • Use the calendar render prop to add aria-label or other SVG attributes to each ContributionGraphBlock, such as the activity count and date.
  • The legend includes native SVG titles such as “0 contributions” for its default swatches.
  • The component is client-only and provides horizontal scrolling for wide calendars; ensure surrounding content communicates the graph's purpose and time range.
  • Color intensity is the primary activity encoding, so provide textual totals or custom labels for users who cannot distinguish the muted color levels.
  • Empty data returns null rather than an empty graph, so provide an external fallback or surrounding context when no activity exists.
