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

What it shows

Decompose profit and loss into supplied contribution streams across periods, including costs.

Live preview

Stacked contributions in basis points, including the cost line: the total is the sum of what you pass in.

<PnlAttributionChart
  periods={["Jan", "Feb", "Mar", "Apr", "May", "Jun"]}
  series={[
    { label: "Trend", values: [42, 18, -12, 51, 34, 22] },
    { label: "Carry", values: [12, 14, 11, 9, 13, 15] },
    { label: "Costs", values: [-11, -9, -13, -10, -12, -14] },
  ]}
  format={{ kind: "number", decimals: 0, suffix: " bps" }}
  height={340}
  ariaLabel="Monthly attribution"
/>

Controls

Height

340px

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.

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

Code

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

<PnlAttributionChart
  periods={["Jan", "Feb", "Mar", "Apr", "May", "Jun"]}
  series={[
    { label: "Trend", values: [42, 18, -12, 51, 34, 22] },
    { label: "Carry", values: [12, 14, 11, 9, 13, 15] },
    { label: "Costs", values: [-11, -9, -13, -10, -12, -14] },
  ]}
  format={{ kind: "number", decimals: 0, suffix: " bps" }}
  height={340}
  ariaLabel="Monthly attribution"
  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 `PnlAttributionChart` 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 { PnlAttributionChart } 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={340}`, `state="ready"`, `ariaLabel="Monthly attribution"`.

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
<PnlAttributionChart
  periods={["Jan", "Feb", "Mar", "Apr", "May", "Jun"]}
  series={[
    { label: "Trend", values: [42, 18, -12, 51, 34, 22] },
    { label: "Carry", values: [12, 14, 11, 9, 13, 15] },
    { label: "Costs", values: [-11, -9, -13, -10, -12, -14] },
  ]}
  format={{ kind: "number", decimals: 0, suffix: " bps" }}
  height={340}
  ariaLabel="Monthly attribution"
  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 { PnlAttributionChart } from "@luc/ui/charts";

<PnlAttributionChart
  periods={["Jan", "Feb", "Mar", "Apr", "May", "Jun"]}
  series={[
    { label: "Trend", values: [42, 18, -12, 51, 34, 22] },
    { label: "Carry", values: [12, 14, 11, 9, 13, 15] },
    { label: "Costs", values: [-11, -9, -13, -10, -12, -14] },
  ]}
  format={{ kind: "number", decimals: 0, suffix: " bps" }}
  height={340}
  ariaLabel="Monthly attribution"
/>

Data contract

`periods` is the shared x axis; each `series[]` has a label and a numeric value per period. Contributions are supplied in basis points or the chosen unit; the chart does not reconcile a missing residual.

Important configuration

Use `format` for basis points or currency, keep the cost stream signed and visible, and state whether the displayed total includes every contribution.

Guidelines

When not to use

Do not let the visual stack imply a total that the supplied rows do not sum to, and do not omit a residual without naming it.
