Indicator chart

ObservationLeft and Right inspect. Escape clears.

ObservationLeft and Right inspect. Up and Down switch series. Escape clears.

Usage

Import the component and the stylesheet once. See Getting started to install the package.

import { IndicatorChartCard } from '@lilt-ui/charts/finance';
import '@lilt-ui/charts/styles.css';

<IndicatorChartCard
  title="SOL · USDC"
  data={candles}
  x="date"
  close="close"
  open="open"
  high="high"
  low="low"
  overlays={['sma']}
  panes={['rsi', 'macd']}
/>

Omit title to leave out the visible title. Set header={false} to remove the whole header, and use aria-label to name a chart inside your own card. legend={false} removes the legend independently. surface="ghost" controls only the visual frame. See Card composition.

Data

Every indicator derives from close: simple and exponential averages, Bollinger bands (20 periods, two deviations), RSI with Wilder’s smoothing (14 by default), and MACD (12, 26, 9). Each needs a warm-up window, so it starts where enough rows exist rather than inventing early values. Without open, high and low the price draws as a line. The same helpers (sma, ema, rsi, macd, bollinger) are exported for your own panes.

// The same rows as a candlestick card. Indicators are computed from the close.
const candles = [
  { date: new Date('2026-08-20'), open: 243.1, high: 246.4, low: 241.8, close: 245.2, volume: 2410000 },
  // …one row per period
];

<IndicatorChartCard
  title="SOL · USDC"
  data={candles}
  x="date"
  close="close"            // the only field indicators need
  overlays={[{ kind: 'ema', period: 21 }, 'bollinger']}
  panes={['rsi', { kind: 'macd', fast: 12, slow: 26, signal: 9 }]}
/>

Props

Every prop IndicatorChartCard accepts, in the order you are likely to reach for them.

Prop	Type	Description
`title`	`string`	Optional visible title. Omit to render no title. Also supplies the accessible name unless aria-label is set.
`data`	`Row[]`	One row per x position. Omit when using ranges.
`x`	`key of Row`	Text, number, or Date field for the x axis.
`close`	`key of Row`	Numeric field holding each close. Every indicator derives from it.
`open`	`key of Row`	With high and low, draws the price as candles.
`high`	`key of Row`	Each period’s high.
`low`	`key of Row`	Each period’s low.
`volume`	`key of Row`	Traded volume, for a volume pane.
`display`	`'candle' \| 'hollow' \| 'ohlc' \| 'line'`	How the price draws. Candles when open, high and low are set; otherwise a line.
`overlays`	`('sma' \| 'ema' \| 'bollinger' \| { kind, period?, deviations? })[]`	Lines over the price. Periods default to 20.
`panes`	`('rsi' \| 'macd' \| 'volume' \| { kind, … })[]`	Linked panes under the price, top to bottom. Defaults to RSI then MACD.
`paneHeight`	`number`	Height of each pane in pixels. Defaults to 72.
`scale`	`'linear' \| 'log'`	Price axis scale.
`live`	`boolean`	Follow the newest row as it arrives.
`depth`	`boolean`	Draws price and indicator lines as lit tubes. Bands and dashed lines stay flat.
`header`	`boolean`	Defaults to true. False removes the whole header: title, headline, delta and period controls, with no reserved space. Pass data directly when your app owns period selection.
`aria-label`	`string`	Accessible chart name, independent of the visible title. Falls back to title, then a generic chart name.
`delta`	`number`	Fractional change for the chip: 0.082 shows +8.2%.
`deltaTone`	`'default' \| 'inverse' \| 'neutral'`	Use inverse when a decrease is good.
`range`	`string`	Static period label in the header.
`ranges`	`{ id, label, data, delta?, headline? }[]`	Turns the period label into a select. Each range swaps the data.
`valueFormat`	`Intl.NumberFormatOptions`	Formats the headline, tiles, and axis, e.g. currency.
`legend`	`false \| 'tiles' \| 'inline' \| 'list' \| 'pills' \| 'bars'`	False removes the legend without changing the data. How the legend under the plot lays out: value tiles (default), a compact inline key, list rows, tinted pills, or bars that also draw each value against the largest.
`legendSwatch`	`'square' \| 'dot' \| 'line'`	The mark beside each legend label. Defaults to a rounded square.
`height`	`number`	Plot height in pixels. Defaults to 240.
`axis`	`'minimal' \| 'dots' \| 'inline' \| 'ruler' \| 'classic' \| 'segmented' \| { x, y }`	Axis preset. Minimal (default) labels only the x ends and has no grid. Set one per axis with `{ x, y }`; a segmented axis can take a `gradient` to read as a range.
`hover`	`'pills' \| 'tooltip' \| 'strip' \| 'headline'`	The one readout for the hovered point: pills on the axes (default), a tooltip with every series, a strip docked above the plot, or the headline and tiles alone.
`hoverStyle`	`'soft' \| 'solid' \| 'accent'`	How the pills or tooltip look. Soft (default) is surface glass; accent tints it with the hovered series.
`pillPosition`	`'auto' \| 'mark' \| 'axis'`	Where the value pill sits: above the hovered mark, or on the y axis. Auto picks mark when there are no y labels.
`tooltipIndicator`	`'square' \| 'dot' \| 'line'`	Series marker on each tooltip row, with hover="tooltip". Square by default.
`background`	`'dots' \| 'grid' \| 'lines' \| 'none'`	Texture behind the marks. Dots by default, with a hover spotlight.
`surface`	`'elevated' \| 'outline' \| 'ghost'`	Card treatment. Ghost removes the visual frame only; header and legend are independent controls.
`palette`	`'iris' \| 'cobalt' \| 'emerald'`	Series colors. Iris by default; explicit series colors still win.
`axisInset`	`number`	Padding between the plot edges and axis labels or pills.
`loading`	`boolean`	Shows a neutral loading skeleton, not data.
`loadingStyle`	`'shimmer' \| 'draw' \| 'breathe'`	Shimmer sweeps a highlight over still shapes; draw reveals them in order; breathe lets them settle. Follows the selected look, including depth, and respects reduced motion.
`empty`	`'dots' \| 'shape' \| ReactElement \| null`	What the card shows when the period has no data. Dots (default) gathers a quiet dot field around the message; shape lays the chart’s own outline behind it. Pass `<ChartEmpty>` with your own words, any element of your own, or null for nothing. Both looks stay still, so empty never reads as loading, and the headline reads a dash, never zero.
`compare`	`boolean \| 'headline' \| 'badge'`	Drag across the plot to compare two points in time. True or headline reads the change in the headline; badge reads it in the card’s tab and leaves the headline at rest.
`sync`	`string`	Link hover and pins with every card that uses the same name, matched by x value. A click pins them all, with a ghost pin on the others; Alt-click pins one card only.
`numberStyle`	`'count' \| 'pop' \| 'slide' \| 'roll' \| 'flow' \| 'scramble'`	How the headline animates when its value changes. Count (default) counts to the new value.
`motion`	`'auto' \| 'none'`	None turns off decorative motion; reduced motion does this automatically.
`defaultRange`	`string`	Initial range id; defaults to the first supplied range.
`locale`	`string`	Locale used for number formatting. Defaults to en-US.
`formatValue`	`(value: number) => string`	Custom value text, taking precedence over valueFormat.
`formatAxisValue`	`(value: number) => string`	Custom compact axis value text.
`formatX`	`(value: string \| number \| Date) => string`	Custom x label text.
`xType`	`'category' \| 'number' \| 'time'`	Override inferred x type. Use time for numeric Unix timestamps in milliseconds.
`spotlight`	`boolean`	Highlight the inspected position in the plot background. Defaults to true.
`badge`	`ReactNode`	Content in the tab above the card. A comparison badge can replace this while a comparison is active.
`className`	`string`	Additional class on the card frame.
`style`	`CSSProperties \| ChartStyle`	Inline styles and scoped --lilt-* chart variables.
`pillValue`	`'series' \| 'stack'`	Read an individual series value (default) or its stacked height. Has no effect when the card has no stacked series.
`decimate`	`boolean`	Defaults to true. Line and Area marks retain at most four observations per pixel column. Other marks draw every row; inspection and summaries always read the full data.
`headline`	`number`	Override the resting headline; an active range headline takes precedence.
`label`	`string`	Names the price series in the hover readout. Defaults to Price.
