ParallelCoordinatesChart

Read a field, a geometry or a spectrum, with the scale handled for you.

@luc/ui/charts

What it shows

Compare several normalized or individually scaled dimensions across rows, revealing trade-offs that a 2D scatter cannot show.

Live preview

Four metrics on one polyline per portfolio: crossings show trade-offs a scatter cannot.

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 { ParallelCoordinatesChart } from "@luc/ui/charts";

<ParallelCoordinatesChart
  axes={[
    { key: "ret", label: "Return", format: { kind: "number", decimals: 1, suffix: "%" } },
    {
      key: "vol",
      label: "Volatility",
      format: { kind: "number", decimals: 1, suffix: "%" },
    },
    { key: "sharpe", label: "Sharpe", format: { kind: "number", decimals: 2 } },
    {
      key: "drawdown",
      label: "Max DD",
      format: { kind: "number", decimals: 1, suffix: "%" },
    },
  ]}
  rows={[
    { ret: 0.9, vol: 14.2, sharpe: 1.24, drawdown: -6.1 },
    { ret: 1.4, vol: 18.6, sharpe: 1.02, drawdown: -9.4 },
    { ret: -0.4, vol: 11.1, sharpe: -0.36, drawdown: -4.2 },
    { ret: 2.1, vol: 22.4, sharpe: 0.94, drawdown: -12.8 },
    { ret: 0.6, vol: 9.8, sharpe: 0.88, drawdown: -3.1 },
    { ret: 1.8, vol: 19.3, sharpe: 1.11, drawdown: -8.6 },

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 `ParallelCoordinatesChart` from Luc UI. It is: Read a field, a geometry or a spectrum, with the scale handled for you.

Import it with: import { ParallelCoordinatesChart } 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="Portfolios across four axes"`.

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
<ParallelCoordinatesChart
  axes={[
    { key: "ret", label: "Return", format: { kind: "number", decimals: 1, suffix: "%" } },
    {
      key: "vol",
      label: "Volatility",
      format: { kind: "number", decimals: 1, suffix: "%" },
    },
    { key: "sharpe", label: "Sharpe", format: { kind: "number", decimals: 2 } },
    {
      key: "drawdown",
      label: "Max DD",
      format: { kind: "number", decimals: 1, suffix: "%" },
    },
  ]}
  rows={[
    { ret: 0.9, vol: 14.2, sharpe: 1.24, drawdown: -6.1 },
    { ret: 1.4, vol: 18.6, sharpe: 1.02, drawdown: -9.4 },
    { ret: -0.4, vol: 11.1, sharpe: -0.36, drawdown: -4.2 },
    { ret: 2.1, vol: 22.4, sharpe: 0.94, drawdown: -12.8 },
    { ret: 0.6, vol: 9.8, sharpe: 0.88, drawdown: -3.1 },
    { ret: 1.8, vol: 19.3, sharpe: 1.11, drawdown: -8.6 },
  ]}
  opacity={0.5}
  height={340}
  ariaLabel="Portfolios across four axes"
  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: Scientific & mathematical

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

<ParallelCoordinatesChart
  axes={[
    { key: "ret", label: "Return", format: { kind: "number", decimals: 1, suffix: "%" } },
    {
      key: "vol",
      label: "Volatility",
      format: { kind: "number", decimals: 1, suffix: "%" },
    },
    { key: "sharpe", label: "Sharpe", format: { kind: "number", decimals: 2 } },
    {
      key: "drawdown",
      label: "Max DD",
      format: { kind: "number", decimals: 1, suffix: "%" },
    },
  ]}
  rows={[
    { ret: 0.9, vol: 14.2, sharpe: 1.24, drawdown: -6.1 },
    { ret: 1.4, vol: 18.6, sharpe: 1.02, drawdown: -9.4 },
    { ret: -0.4, vol: 11.1, sharpe: -0.36, drawdown: -4.2 },
    { ret: 2.1, vol: 22.4, sharpe: 0.94, drawdown: -12.8 },
    { ret: 0.6, vol: 9.8, sharpe: 0.88, drawdown: -3.1 },
    { ret: 1.8, vol: 19.3, sharpe: 1.11, drawdown: -8.6 },
  ]}
  opacity={0.5}
  height={340}
  ariaLabel="Portfolios across four axes"
/>

Data contract

`axes` defines each dimension's key and range; each `rows[]` entry supplies one value per axis. The caller owns normalisation and must not compare mismatched scales without saying so.

Important configuration

Set axis ranges explicitly, use `opacity` to manage overplotting, and highlight one row with a semantic tone when one comparison is the subject.

Guidelines

When not to use

Do not make raw variables with incomparable units look interchangeable by leaving every axis on the same visual height without a documented scale.
