Inputs
Section titled “Inputs”| Input | Type | Default | Description |
|---|---|---|---|
label |
string |
Required. Chart title: visible text and the accessible name of the plot (aria-labelledby). | |
hideLabel |
boolean |
false |
Visually hide the title; it stays the accessible name. |
description |
string |
Visible description below the title, also referenced by aria-describedby (text only). | |
summary |
string |
Replaces the generated accessible summary (aria-describedby). | |
valueFormat |
NumberFormatOptions |
Number format for values in tooltips, labels, the data table, the summary, and axis ticks (ticks use fixed fraction digits). | |
formatValue |
(value: number) => string |
Custom value text; overrides valueFormat everywhere except axis ticks. | |
x |
readonly LineChartXValue[] |
Required. Shared x values, one per point: strings (category axis), numbers (linear axis), or instants (time axis). Numbers and instants must be ascending. | |
series |
readonly ChartSeries[] |
Required. Series: { id, label, values: (number | null)[], color?: 1-8 }. values has exactly one entry per x value; null, NaN, and infinities are gaps. | |
area |
boolean |
false |
Fill the area between each line and the zero baseline (includes zero in the domain). |
xType |
LineChartXType |
Axis type. Default: inferred from the first x value. | |
xAxis |
LineChartAxis |
X axis title and approximate tick count (2-20). | |
yAxis |
LineChartYAxis |
Y axis title, tick count, fixed domain, and zero inclusion (default true with area). | |
formatX |
(value: LineChartXValue, index: number) => string |
Custom x text for tooltips, labels, the table, and the summary. | |
timeFormat |
Omit<DateTimeFormatOptions, "timeZone"> |
Date format of time x values. Default: chosen from the data resolution (year, month, day, minute, second). | |
zoom |
boolean |
false |
Zoom and pan along x: a Zoom toolbar (Zoom in, Zoom out, Reset zoom), +/= and - and 0 keys on a focused point, arrow keys past the window edge pan, Ctrl/Cmd + wheel, drag to pan a zoomed chart, Shift + drag to select a range. Turning it off resets the window. |
legend |
ChartLegendMode |
'auto' |
auto: legend when there is more than one series (pie charts: always). |
dataTable |
ChartTableMode |
'toggle' |
Data table fallback with the exact data: behind a Show data table button (built on first open), always visible, visually hidden (screen readers only), or none. |
tooltip |
boolean |
true |
Tooltip on pointer hover and keyboard focus. |
patterns |
boolean |
false |
Dash patterns and texture fills so series never differ by color alone. Off by default (plain colors); always on in forced colors. Turn it on when series are told apart by color alone (grouped or stacked series, multi-slice pies) and no labels carry the distinction (WCAG 1.4.1). |
height |
number |
'300' |
Plot height in CSS px (integer 120-2000); the width follows the container. |
