TermStructureChart

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

What it shows

Compare rate or price curves across an ordered set of tenors.

Live preview

Rates already in percent units, two curves on a shared ordered tenor axis.

<TermStructureChart
  tenors={["1M", "3M", "6M", "1Y", "2Y", "5Y"]}
  curves={[
    {
      name: "Latest",
      values: [4.35, 4.42, 4.51, 4.58, 4.62, 4.66],
      tone: "accent",
      emphasis: true,
    },
    {
      name: "One week ago",
      values: [4.72, 4.68, 4.63, 4.59, 4.55, 4.52],
      tone: "neutral",
      lineType: "dashed",
    },
  ]}
  yLabel="Rate"
  format={{ kind: "percent", decimals: 2 }}
  height={320}
  ariaLabel="Rate curve"
/>

Controls

Height

320px

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

<TermStructureChart
  tenors={["1M", "3M", "6M", "1Y", "2Y", "5Y"]}
  curves={[
    {
      name: "Latest",
      values: [4.35, 4.42, 4.51, 4.58, 4.62, 4.66],
      tone: "accent",
      emphasis: true,
    },
    {
      name: "One week ago",
      values: [4.72, 4.68, 4.63, 4.59, 4.55, 4.52],
      tone: "neutral",
      lineType: "dashed",
    },
  ]}
  yLabel="Rate"
  format={{ kind: "percent", decimals: 2 }}
  height={320}
  ariaLabel="Rate curve"
  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 `TermStructureChart` 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 { TermStructureChart } 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={320}`, `state="ready"`, `ariaLabel="Rate curve"`.

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
<TermStructureChart
  tenors={["1M", "3M", "6M", "1Y", "2Y", "5Y"]}
  curves={[
    {
      name: "Latest",
      values: [4.35, 4.42, 4.51, 4.58, 4.62, 4.66],
      tone: "accent",
      emphasis: true,
    },
    {
      name: "One week ago",
      values: [4.72, 4.68, 4.63, 4.59, 4.55, 4.52],
      tone: "neutral",
      lineType: "dashed",
    },
  ]}
  yLabel="Rate"
  format={{ kind: "percent", decimals: 2 }}
  height={320}
  ariaLabel="Rate curve"
  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 { TermStructureChart } from "@luc/ui/charts";

<TermStructureChart
  tenors={["1M", "3M", "6M", "1Y", "2Y", "5Y"]}
  curves={[
    {
      name: "Latest",
      values: [4.35, 4.42, 4.51, 4.58, 4.62, 4.66],
      tone: "accent",
      emphasis: true,
    },
    {
      name: "One week ago",
      values: [4.72, 4.68, 4.63, 4.59, 4.55, 4.52],
      tone: "neutral",
      lineType: "dashed",
    },
  ]}
  yLabel="Rate"
  format={{ kind: "percent", decimals: 2 }}
  height={320}
  ariaLabel="Rate curve"
/>

Data contract

`tenors` is the ordered shared x axis; every `curves[]` entry has a name and a `values` array of the same length. Values are already expressed in the chosen unit.

Important configuration

Use `yLabel` and `format` to state percent versus basis points, and distinguish curves with `emphasis` and line style rather than arbitrary colour.

Guidelines

When not to use

Do not reorder tenors for visual convenience or put curves with different quotation conventions on the same axis.
