HistoricalPositionChart

Read a market, a risk or a return, with the axis and the tooltip wired for the job.

@luc/ui/charts

What it shows

Place one current reading on a supplied historical quantile band.

Live preview

One served percentile on a quantile band: the reading is yours, the band is the chart's.

+4.1 %78th percentile

<HistoricalPositionChart
  percentile={78}
  value="+4.1 %"
  percentileLabel="78th percentile"
  height={56}
  ariaLabel="Position in history"
/>

Controls

Modified

Height

200px

A chart measures its container, so it always needs a definite height.

State

The surface the chart is in — loading, empty and error are drawn by the component.

Accessible name

A drawing is not readable by a screen reader, so it needs a name that states what it shows.

+4.1 %78th percentile

The same fixture as the live preview above; the controls change how it is drawn, not what it measures.

Code

import { HistoricalPositionChart } from "@luc/ui/charts";

<HistoricalPositionChart
  percentile={78}
  value="+4.1 %"
  percentileLabel="78th percentile"
  height={200}
  ariaLabel="Position in history"
  state="ready"
/>

Copy for an AI agentA specification an agent can act on: the import, the setup, the chosen props, the data contract and the accessibility expectation.

Implement `HistoricalPositionChart` from Luc UI. It is: Read a market, a risk or a return, with the axis and the tooltip wired for the job.

Import it with: import { HistoricalPositionChart } from "@luc/ui/charts";
Requires: react ^19.0.0; react-dom ^19.0.0; react-hook-form ^7.0.0 (optional, for @luc/ui/forms/react-hook-form); tailwindcss ^4.0.0; node >= 22 (repository tools). Import the stylesheet once at the app root and wrap the tree in `LucProvider`. Both come from the package that publishes @luc.

Chosen configuration: `height={200}`, `state="ready"`, `ariaLabel="Position in history"`.

Accessibility: keep the component's own semantics. Do not re-implement its ARIA wiring, do not add roles it does not declare, and make sure every interactive element is reachable and operable from the keyboard with a visible focus state.
Styling: use Luc UI design tokens and the component's own props. Do not restyle with raw colour literals and do not override the component's internal structure with page CSS.
Motion: respect `prefers-reduced-motion`. The component already does, so do not disable it.

Reproduce this state:
```tsx
<HistoricalPositionChart
  percentile={78}
  value="+4.1 %"
  percentileLabel="78th percentile"
  height={200}
  ariaLabel="Position in history"
  state="ready"
/>
```

Usage

The values are prepared by the caller: this component draws the points it is given and computes no statistic of its own, so units, scaling and any summary have to be settled before the data reaches it.

It is drawn by the ECharts engine.

Worked examples with real data are on the family overview: Financial & quantitative

import { HistoricalPositionChart } from "@luc/ui/charts";

<HistoricalPositionChart
  percentile={78}
  value="+4.1 %"
  percentileLabel="78th percentile"
  height={56}
  ariaLabel="Position in history"
/>

Data contract

`percentile` and `value` describe the reading; the component draws the band and the marker, not a historical time series. The percentile is the caller's classification.

Important configuration

Use `percentileLabel` to name the band, format the value in its measurement unit, and state the lookback window in the caption.

Guidelines

When not to use

Do not call the reading expensive or cheap from position alone; the percentile is descriptive and the threshold belongs to the analysis.
