Usage

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

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

function Demo() {
  return (
    <AreaChart
      h={300}
      data={data}
      dataKey="date"
      series={[
        { name: 'Apples', color: 'indigo.6' },
        { name: 'Oranges', color: 'blue.6' },
        { name: 'Tomatoes', color: 'teal.6' },
      ]}
      curveType="linear"
    />
  );
}

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.

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

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

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.

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

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

Split area chart

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

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

function Demo() {
  return (
    <AreaChart
      h={300}
      data={data}
      dataKey="date"
      type="split"
      strokeWidth={1}
      dotProps={{ r: 2, strokeWidth: 1 }}
      activeDotProps={{ r: 3, strokeWidth: 1 }}
      series={[{ name: 'Apples', color: 'bright' }]}
    />
  );
}

Split colors

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

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

function Demo() {
  return (
    <AreaChart
      h={300}
      data={data}
      dataKey="date"
      type="split"
      strokeWidth={1}
      dotProps={{ r: 2, strokeWidth: 1 }}
      activeDotProps={{ r: 3, strokeWidth: 1 }}
      series={[{ name: 'Apples', color: 'bright' }]}
      splitColors={['violet', 'orange']}
    />
  );
}

Legend

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

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

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

Legend position

You can pass props down to recharts Legend component with 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.

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

function Demo() {
  return (
    <AreaChart
      h={300}
      data={data}
      dataKey="date"
      type="stacked"
      withLegend
      legendProps={{ verticalAlign: 'bottom', height: 50 }}
      series={[
        { name: 'Apples', color: 'indigo.6' },
        { name: 'Oranges', color: 'blue.6' },
        { name: 'Tomatoes', color: 'teal.6' },
      ]}
    />
  );
}

Series labels

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

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

function Demo() {
  return (
    <AreaChart
      h={300}
      data={data}
      dataKey="date"
      type="stacked"
      withLegend
      legendProps={{ verticalAlign: 'bottom' }}
      series={[
        { name: 'Apples', label: 'Apples sales', color: 'indigo.6' },
        { name: 'Oranges', label: 'Oranges sales', color: 'blue.6' },
        { name: 'Tomatoes', label: 'Tomatoes sales', color: 'teal.6' },
      ]}
    />
  );
}

Connect nulls

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

Curve type

Connect nulls

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

function Demo() {
  return (
    <AreaChart
      h={300}
      data={data}
      dataKey="date"
      series={[{ name: 'Apples', color: 'indigo.6' }]}
      curveType="linear"
      connectNulls
    />
  );
}

X and Y axis props

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

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

function Demo() {
  return (
    <AreaChart
      h={300}
      data={data}
      dataKey="date"
      type="stacked"
      tickLine="xy"
      yAxisProps={{ tickMargin: 15, orientation: 'right' }}
      xAxisProps={{ tickMargin: 15, orientation: 'top' }}
      series={[
        { name: 'Apples', color: 'indigo.6' },
        { name: 'Oranges', color: 'blue.6' },
        { name: 'Tomatoes', color: 'teal.6' },
      ]}
    />
  );
}

Axis labels

Use xAxisLabel and yAxisLabel props to display axis labels:

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

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

X axis offset

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

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

function Demo() {
  return (
    <AreaChart
      h={300}
      data={data}
      dataKey="date"
      type="stacked"
      xAxisProps={{ padding: { left: 30, right: 30 } }}
      series={[
        { name: 'Apples', color: 'indigo.6' },
        { name: 'Oranges', color: 'blue.6' },
        { name: 'Tomatoes', color: 'teal.6' },
      ]}
    />
  );
}

Y axis scale

Use yAxisProps to change 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 domain to [0, 100]:

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

function Demo() {
  return (
    <AreaChart
      h={300}
      data={data}
      dataKey="date"
      yAxisProps={{ domain: [0, 100] }}
      series={[{ name: 'Apples', color: 'indigo.6' }]}
    />
  );
}

Rotate x-axis labels

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

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

function Demo() {
  return (
    <AreaChart
      h={300}
      data={data}
      dataKey="date"
      type="stacked"
      tickLine="xy"
      xAxisProps={{ angle: -20 }}
      series={[
        { name: 'Apples', color: 'indigo.6' },
        { name: 'Oranges', color: 'blue.6' },
        { name: 'Tomatoes', color: 'teal.6' },
      ]}
    />
  );
}

Value formatter

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

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

function Demo() {
  return (
    <AreaChart
      h={300}
      data={data}
      dataKey="date"
      type="stacked"
      valueFormatter={(value) => new Intl.NumberFormat('en-US').format(value)}
      series={[
        { name: 'Apples', color: 'indigo.6' },
        { name: 'Oranges', color: 'blue.6' },
        { name: 'Tomatoes', color: 'teal.6' },
      ]}
    />
  );
}

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.

Color

With gradient

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

function Demo() {
  return (
    <AreaChart
      h={300}
      data={data}
      dataKey="date"
      withGradient
      series={[{ name: 'Apples', color: 'blue' }]}
    />
  );
}

Change area color depending on color scheme

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

import { AreaChart } from '@mantine/charts';
import { data } from './data';
import classes from './Demo.module.css';

function Demo() {
  return (
    <AreaChart
      h={300}
      data={data}
      dataKey="date"
      className={classes.root}
      series={[{ name: 'Apples', color: 'var(--area-color)' }]}
    />
  );
}

Stroke dash array

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

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

function Demo() {
  return (
    <AreaChart
      h={300}
      data={data}
      dataKey="date"
      type="stacked"
      strokeDasharray="15 15"
      series={[
        { name: 'Apples', color: 'indigo.6' },
        { name: 'Oranges', color: 'blue.6' },
        { name: 'Tomatoes', color: 'teal.6' },
      ]}
    />
  );
}

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:

.root {
  @mixin light {
    --chart-grid-color: alpha(var(--mantine-color-black), 0.15);
    --chart-text-color: var(--mantine-color-gray-7);
  }

  @mixin dark {
    --chart-grid-color: alpha(var(--mantine-color-white), 0.15);
    --chart-text-color: var(--mantine-color-dark-0);
  }
}

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

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 tooltipAnimationDuration prop to a number of milliseconds to animate the tooltip position change.

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

function Demo() {
  return (
    <AreaChart
      h={300}
      data={data}
      dataKey="date"
      type="stacked"
      tooltipAnimationDuration={200}
      series={[
        { name: 'Apples', color: 'indigo.6' },
        { name: 'Oranges', color: 'blue.6' },
        { name: 'Tomatoes', color: 'teal.6' },
      ]}
    />
  );
}

Units

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

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

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

Custom tooltip

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

import { AreaChart, getFilteredChartTooltipPayload } from '@mantine/charts';
import { Paper, Text } from '@mantine/core';
import { data } from './data';

interface ChartTooltipProps {
  label: string;
  payload: Record<string, any>[] | undefined;
}

function ChartTooltip({ label, payload }: ChartTooltipProps) {
  if (!payload) return null;

  return (
    <Paper px="md" py="sm" withBorder shadow="md" radius="md">
      <Text fw={500} mb={5}>
        {label}
      </Text>
      {getFilteredChartTooltipPayload(payload).map((item: any) => (
        <Text key={item.name} c={item.color} fz="sm">
          {item.name}: {item.value}
        </Text>
      ))}
    </Paper>
  );
}

function Demo() {
  return (
    <AreaChart
      h={300}
      data={data}
      dataKey="date"
      type="stacked"
      tooltipProps={{
        content: ({ label, payload }) => <ChartTooltip label={label} payload={payload} />,
      }}
      series={[
        { name: 'Apples', color: 'indigo.6' },
        { name: 'Oranges', color: 'blue.6' },
        { name: 'Tomatoes', color: 'teal.6' },
      ]}
    />
  );
}

Remove tooltip

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

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

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

Customize dots

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

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

function Demo() {
  return (
    <AreaChart
      h={300}
      data={data}
      dataKey="date"
      type="stacked"
      dotProps={{ r: 6, strokeWidth: 2, stroke: '#fff' }}
      activeDotProps={{ r: 8, strokeWidth: 1, fill: '#fff' }}
      series={[
        { name: 'Apples', color: 'indigo.6' },
        { name: 'Oranges', color: 'blue.6' },
        { name: 'Tomatoes', color: 'teal.6' },
      ]}
    />
  );
}

Stroke width

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

Stroke width

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

function Demo() {
  return (
    <AreaChart
      h={300}
      data={data}
      dataKey="date"
      series={[
        { name: 'Apples', color: 'indigo.6' },
        { name: 'Oranges', color: 'blue.6' },
        { name: 'Tomatoes', color: 'teal.6' },
      ]}
      strokeWidth={2}
    />
  );
}

Fill opacity

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

Type

default

stacked

Fill opacity

With gradient

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

function Demo() {
  return (
    <AreaChart
      h={300}
      data={data}
      dataKey="date"
      series={[
        { name: 'Apples', color: 'indigo.6' },
        { name: 'Tomatoes', color: 'teal.6' },
        { name: 'Oranges', color: 'blue.6' },
      ]}
      fillOpacity={0.2}
    />
  );
}

Sync multiple AreaCharts

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

Apples sales:

Tomatoes sales:

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

function Demo() {
  return (
    <>
      <Text mb="md" pl="md">
        Apples sales:
      </Text>

      <AreaChart
        h={180}
        data={data}
        dataKey="date"
        series={[{ name: 'Apples', color: 'indigo.6' }]}
        areaChartProps={{ syncId: 'groceries' }}
      />

      <Text mb="md" pl="md" mt="xl">
        Tomatoes sales:
      </Text>

      <AreaChart
        h={180}
        data={data}
        dataKey="date"
        areaChartProps={{ syncId: 'groceries' }}
        series={[{ name: 'Tomatoes', color: 'teal.6' }]}
      />
    </>
  );
}

Vertical orientation

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

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

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

Dashed area line

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

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

function Demo() {
  return (
    <AreaChart
      h={300}
      data={data}
      dataKey="date"
      type="stacked"
      strokeWidth={1}
      dotProps={{ r: 2 }}
      activeDotProps={{ r: 3, strokeWidth: 1 }}
      series={[
        { name: 'Apples', color: 'indigo.6' },
        { name: 'Oranges', color: 'blue.6' },
        { name: 'Tomatoes', color: 'teal.6', strokeDasharray: '5 5' },
      ]}
    />
  );
}

Reference lines

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

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

function Demo() {
  return (
    <AreaChart
      h={300}
      data={data}
      dataKey="date"
      yAxisProps={{ domain: [0, 100] }}
      referenceLines={[
        { y: 40, label: 'Average sales', color: 'red.6' },
        { x: 'Mar 25', label: 'Report out' },
      ]}
      series={[{ name: 'Apples', color: 'indigo.6' }]}
    />
  );
}
