Quick Start

Installation

bash

npm install @syncfusion/ej2-react-charts --save

Basic Sparkline

javascript

import { SparklineComponent } from '@syncfusion/ej2-react-charts';
import * as React from 'react';
import * as ReactDOM from 'react-dom';

function App() {
  const data = [0, 6, 4, 1, 3, 2, 5];
  
  return (
    <SparklineComponent
      dataSource={data}
      type="Line"
      height="150px"
      width="300px"
    />
  );
}

export default App;
ReactDOM.render(<App />, document.getElementById('charts'));

Sparkline with Tooltip

javascript

import { SparklineComponent, Inject, SparklineTooltip } from '@syncfusion/ej2-react-charts';
import * as React from 'react';
import * as ReactDOM from 'react-dom';

function App() {
  const data = [0, 6, 4, 1, 3, 2, 5];
  
  return (
    <SparklineComponent
      dataSource={data}
      type="Area"
      height="150px"
      width="300px"
      tooltipSettings={{ visible: true, format: '${x} : ${y}' }}
    >
      <Inject services={[SparklineTooltip]} />
    </SparklineComponent>

    <SparklineComponent
      dataSource={data}
      type="Area"
      height="150px"
      width="300px"
      rangeBandSettings={[
        { startRange: 1, endRange: 3, color: '#bfd4fc', opacity: 0.4 }
      ]}
    />
  );
}

export default SparklineWithRangeBand;
ReactDOM.render(<SparklineWithRangeBand />, document.getElementById('charts'));
