Line consumes context provided by these components:
activeDotFunction | Partial<ActiveDotProps> | ReactNode | false | trueoptional
The active dot is rendered on the closest data point when user interacts with the chart. Options:
false: dots do not change on user activity; both active and inactive dots follow thedotprop (see below)true: renders the active dot with default settingsobject: the props of the active dot. This will be merged with the internal calculated props of the active dotReactElement: the custom active dot elementfunction: a render function of the custom active dot
DEFAULT:
trueFORMAT:
<Line dataKey="value" activeDot={false} /> <Line dataKey="value" activeDot={{ stroke: 'red', strokeWidth: 2, r: 10 }} /> <Line dataKey="value" activeDot={CustomizedActiveDot} />animateNewValuesbooleanoptional
DEFAULT:
trueanimationBeginnumberoptional
Specifies when the animation should begin, the unit of this option is ms.
DEFAULT:
0animationDurationnumberoptional
Specifies the duration of animation, the unit of this option is ms.

1500animationEasing"ease" | "ease-in" | "ease-in-out" | "ease-out" | "linear" | "spring" | EasingFunction | `cubic-bezier(${number},${number},${number},${number})`optional
The type of easing function.
DEFAULT:
"ease"animationInterpolateFnAnimationInterpolateFn<LinePointItem, CartesianLayout>optional
Custom animation function for interpolating data items. When provided, this replaces the default animation interpolation.
Available since Recharts 3.9
Examples:
animationMatchBy"append" | "index" | AnimationMatchBy<LinePointItem>optional
Strategy for matching previous items to next items during animation. Determines how Recharts pairs old data points with new data points to create smooth transitions.
matchByIndex(default): match by array position with proportional stretchingmatchAppend: match sequentially by index and treat newly appended items as newmatchByDataKey('someKey'): match by a data key from the payload- Custom function
(item, index) => key: match by the returned key
Available since Recharts 3.9

"index"Examples:
childrenReactNodeoptional
Examples:
classNamestringoptional
connectNullsbooleanoptional
Whether to connect the curve across null points.
DEFAULT:
falsedangerouslySetInnerHTMLObjectoptional
dataReadonlyArray<DataPointType>optional
The source data. Each element should be an object. The properties of each object represent the values of different data dimensions.
Use the
dataKeyprop to specify which properties to use.FORMAT:
data={[{ name: 'a', value: 12 }]} data={[{ label: 'foo', measurements: [5, 12] }]}dataKeyTypedDataKey<DataPointType, DataValueType>optional
The data that you provide via the
dataprop is an array of objects. Each object can have multiple properties, each representing a different data dimension. Use thedataKeyprop to specify which property (or dimension) to use for this component.Typically, you will want to have one dataKey on the X axis, and different dataKey on the Y axis, where they extract different values from the same data objects.
Decides how to extract the value from the data:
string: the name of the field in the data object;number: the index of the field in the data;function: a function that receives the data object and returns the value.
dotFunction | Partial<Props> | ReactNode | false | trueoptional
Renders a circle element at each data point. Options:
false: no dots are drawn;true: renders the dots with default settings;object: the props of the dot. This will be merged with the internal calculated props of each dot;ReactElement: the custom dot element;function: a render function of the custom dot.
DEFAULT:
trueFORMAT:
<Line dataKey="value" dot={false} /> <Line dataKey="value" dot={{ stroke: 'red', strokeWidth: 2 }} /> <Line dataKey="value" dot={CustomizedDot} />formatterFormatteroptional
Formats the value displayed in the tooltip for this Line. When set, takes precedence over the
formatterprop on the Tooltip component.hidebooleanoptional
Hides the whole graphical element when true.
Hiding an element is different from removing it from the chart: Hidden graphical elements are still visible in Legend, and can be included in axis domain calculations, depending on
includeHiddenprops of your XAxis/YAxis.DEFAULT:
falseidstringoptional
Unique identifier of this component. Used as an HTML attribute
id, and also to identify this element internally.If undefined, Recharts will generate a unique ID automatically.
isAnimationActive"auto" | false | trueoptional
If set false, animation of line will be disabled. If set "auto", the animation will be disabled in SSR and will respect the user's prefers-reduced-motion system preference for accessibility.
DEFAULT:
"auto"labelFunction | Props | ReactNode | false | trueoptional
Renders one label for each data point. Options:
true: renders default labels;false: no labels are rendered;object: the props of LabelList component;ReactElement: a custom SVG label element, such as<text>or<g>. HTML elements such as<div>are not valid inside the chart SVG and may trigger React DOM warnings.function: a render function of custom label.
DEFAULT:
falseFORMAT:
<Line dataKey="value" label /> <Line dataKey="value" label={{ fill: 'red', fontSize: 20 }} /> <Line dataKey="value" label={CustomizedLabel} />Examples:
legendType"circle" | "cross" | "diamond" | "line" | "none" | "plainline" | "rect" | "square" | "star" | "triangle" | "wye"optional
The type of icon in legend. If set to 'none', no legend item will be rendered.
DEFAULT:
"line"Examples:
namestringoptional
The name of data. This option will be used in tooltip and legend to represent this graphical item. If no value was set to this option, the value of dataKey will be used alternatively.
pathstringoptional
shape(union of 5 variants)optional
If set a ReactElement, the shape of line can be customized. If set a function, the function will be called to render customized shape.
During animations the shape receives additional props:
animationElapsedTime,isAnimating, andisEntrance. When a custom shape is provided, the built-in stroke-dasharray entrance animation is skipped.FORMAT:
<Line dataKey="value" shape={CustomizedShapeComponent} /> <Line dataKey="value" shape={renderShapeFunction} />Examples:
strokestringoptional
The stroke color. If
"none", no line will be drawn.DEFAULT:
"#3182bd"strokeDasharraynumber | stringoptional
The pattern of dashes and gaps used to paint the line.
FORMAT:
strokeDasharray="5 5" strokeDasharray={10} <Line strokeDasharray="4" /> <Line strokeDasharray="4 1" /> <Line strokeDasharray="4 1 2" />strokeWidthnumber | stringoptional
The width of the stroke

The id of YAxis which is corresponding to the data. Required when there are multiple YAxes.
DEFAULT:
0zIndexnumberoptional
Z-Index of this component and its children. The higher the value, the more on top it will be rendered. Components with higher zIndex will appear in front of components with lower zIndex. If undefined or 0, the content is rendered in the default layer without portals.
