Usage

Use the AreaChart component without the type prop to render a regular area chart. In a regular area chart, each data series is plotted independently and does not interact with other series.

<Demo data={AreaChartDemos.usage} />

Stacked area chart

Set type="stacked" to render a stacked area chart. In this type of area chart, stacking is applied along the vertical axis, allowing you to see the overall trend as well as the contribution of each individual series to the total.

<Demo data={AreaChartDemos.stacked} />

Percent area chart

Set type="percent" to render a percent area chart. In this type of area chart, the y-axis scale is always normalized to 100%, making it easier to compare the contribution of each series in terms of percentages.

<Demo data={AreaChartDemos.percent} />

Split area chart

Set type="split" to render a split area chart. In this type of area chart, the fill color is split into two colors: one for positive values and one for negative values. Split area charts support only one data series.

<Demo data={AreaChartDemos.split} />

Split colors

Set the splitColors prop to an array of two colors to customize the fill color of a split area chart. The first color is used for positive values and the second color is used for negative values. The splitColors prop is ignored in other types of area charts.

<Demo data={AreaChartDemos.splitColors} />

Legend

To display the chart legend, set the withLegend prop. When one of the items in the legend is hovered, the corresponding data series is highlighted in the chart.

<Demo data={AreaChartDemos.legend} />

Legend position

You can pass props down to the recharts Legend component with the legendProps prop. For example, setting legendProps={{ verticalAlign: 'bottom', height: 50 }} will render the legend at the bottom of the chart and set its height to 50px.

<Demo data={AreaChartDemos.legendPosition} />

Series labels

By default, the series name is used as a label. To change it, set the label property in the series object:

<Demo data={AreaChartDemos.seriesLabels} />

Set curve type per line

You can set individual curve types for each line in the series array. If you do not set a curve type for a line, the series will fall back to curveType prop, or monotone if curveType is not set.

<Demo data={AreaChartDemos.curveType} />

Connect nulls

Use the connectNulls prop to specify whether to connect a data point across null points. By default, connectNulls is true.

<Demo data={AreaChartDemos.connectNulls} />

Points labels

To display labels on data points, set withPointLabels:

<Demo data={AreaChartDemos.pointLabels} />

X and Y axis props

Use xAxisProps and yAxisProps to pass props down to the recharts XAxis and YAxis components. For example, these props can be used to change the orientation of the axis:

<Demo data={AreaChartDemos.axisProps} />

Axis labels

Use xAxisLabel and yAxisLabel props to display axis labels:

<Demo data={AreaChartDemos.axisLabels} />

X axis offset

Use xAxisProps to set padding between the chart ends and the x-axis:

<Demo data={AreaChartDemos.xAxisOffset} />

Y axis scale

Use yAxisProps to change the domain of the Y axis. For example, if you know that your data will always be in the range of 0 to 100, you can set the domain to [0, 100]:

<Demo data={AreaChartDemos.yScale} />

Right Y axis

To display an additional Y axis on the right side of the chart, set the withRightYAxis prop. You can pass props down to the recharts YAxis component with the rightYAxisProps prop and assign a label to the right Y axis with the rightYAxisLabel prop. Note that you need to bind data series to the right Y axis by setting yAxisId in the series object.

<Demo data={AreaChartDemos.rightYAxis} />

Rotate x-axis labels

To rotate x-axis labels, set xAxisProps.angle to the number of degrees to rotate:

<Demo data={AreaChartDemos.rotateLabels} />

Value formatter

To format values in the tooltip and axis ticks, use the valueFormat prop. It accepts a function that takes a number value as an argument and returns a formatted value:

<Demo data={AreaChartDemos.valueFormatter} />

Area color

You can reference colors from theme the same way as in other components, for example, blue, red.5, orange.7, etc. Any valid CSS color value is also accepted.

<Demo data={AreaChartDemos.color} />

Change area color depending on color scheme

You can use CSS variables in the color property. To define a CSS variable that changes depending on the color scheme, use light/dark mixins or the light-dark function. Example of an area that is dark orange in light mode and lime in dark mode:

<Demo data={AreaChartDemos.colorSchemeColor} />

Stroke dash array

Set the strokeDasharray prop to control the stroke dash array of the grid and cursor lines. The value represents the lengths of alternating dashes and gaps. For example, strokeDasharray="10 5" will render a dashed line with 10px dashes and 5px gaps.

<Demo data={AreaChartDemos.strokeDasharray} />

Grid and text colors

Use --chart-grid-color and --chart-text-color to change colors of grid lines and text within the chart. With CSS modules, you can change colors depending on color scheme:

<Demo data={AreaChartDemos.gridColor} />

If your application has only one color scheme, you can use the gridColor and textColor props instead of CSS variables:

tsx
import { AreaChart } from '@mantine/charts';
import { data } from './data';

function Demo() {
  return (
    <AreaChart
      h={300}
      data={data}
      dataKey="date"
      type="stacked"
      gridColor="gray.5"
      textColor="gray.9"
      series={[
        { name: 'Apples', color: 'indigo.6' },
        { name: 'Oranges', color: 'blue.6' },
        { name: 'Tomatoes', color: 'teal.6' },
      ]}
    />
  );
}

Tooltip animation

By default, tooltip animation is disabled. To enable it, set the tooltipAnimationDuration prop to a number of milliseconds to animate the tooltip position change.

<Demo data={AreaChartDemos.tooltipAnimation} />

Units

Set the unit prop to render a unit label next to the y-axis ticks and tooltip values:

<Demo data={AreaChartDemos.unit} />

Custom tooltip

Use tooltipProps.content to pass a custom tooltip renderer to the recharts Tooltip component. Note that it is required to filter the recharts payload with the getFilteredChartTooltipPayload function to remove empty values that are used for styling purposes only.

<Demo data={AreaChartDemos.customTooltip} />

Remove tooltip

To remove the tooltip, set withTooltip={false}. This also removes the cursor line and disables interactions with the chart.

<Demo data={AreaChartDemos.noTooltip} />

Customize dots

Use dotProps to pass props down to the recharts dot in regular state and activeDotProps to pass props down to the recharts dot in active state (when the cursor is over the current series).

<Demo data={AreaChartDemos.dotProps} />

Stroke width

Use the strokeWidth prop to control the stroke width of all areas:

<Demo data={AreaChartDemos.strokeWidth} />

Fill opacity

Use the fillOpacity prop to control the fill opacity of all areas:

<Demo data={AreaChartDemos.fillOpacity} />

Sync multiple AreaCharts

You can pass props down to the recharts AreaChart component with the areaChartProps prop. For example, setting areaChartProps={{ syncId: 'any-id' }} will sync the tooltip of multiple AreaChart components with the same syncId prop.

<Demo data={AreaChartDemos.sync} />

Vertical orientation

Set orientation="vertical" to render a vertical area chart:

<Demo data={AreaChartDemos.vertical} />

Dashed area line

Set the strokeDasharray property in series to change the line style to dashed:

<Demo data={AreaChartDemos.lineDasharray} />

Reference lines

Use the referenceLines prop to render reference lines. Reference lines are always rendered behind the chart.

<Demo data={AreaChartDemos.referenceLines} />

Reference area

Use the ReferenceArea component from recharts to display a reference area:

<Demo data={AreaChartDemos.referenceArea} />
