The appearance of the sparkline can be customized using margin, container Area border, and container Area background.

Sparkline border

The containerArea border of the sparkline is used to render border to cover sparkline area.

The following code example shows the sparkline with overall border.

import * as React from 'react';
import * as ReactDOM from "react-dom";
import { SparklineComponent } from '@syncfusion/ej2-react-charts';
export class App extends React.Component {
    render() {
        return (<SparklineComponent id='sparkline' height='200px' width='350px' containerArea={{
                border: { color: '#033e96', width: 2 }
            }} border={{
                color: '#033e96', width: 1
            }} type='Area' fill='#b2cfff' dataSource={[3, 6, 4, 1, 3, 2, 5]}>
        </SparklineComponent>);
    }
}
ReactDOM.render(<App />, document.getElementById('sparkline'));
import * as React from 'react';
import * as ReactDOM from "react-dom";
import { SparklineComponent } from '@syncfusion/ej2-react-charts';

function App() {

  return ( <SparklineComponent id='sparkline'
    height='200px' width='350px'
    containerArea= { {
        border: { color: '#033e96', width: 2 }
    }}
    border= { {
        color: '#033e96', width: 1
    }}
    type= 'Area'
    fill= '#b2cfff'
    dataSource={[ 3, 6, 4, 1, 3, 2, 5]}>
</SparklineComponent> );
 
}
export default App;
ReactDOM.render(<App />, document.getElementById('sparkline'));

Sparkline padding

Padding is used to specify padding value between container and sparkline. By default, padding value of the sparkline is 5. Sparkline padding values are specified by the left, right, top, and bottom.

The following code example shows the sparkline with overall padding is set to 20.

import * as React from 'react';
import * as ReactDOM from "react-dom";
import { SparklineComponent } from '@syncfusion/ej2-react-charts';
export class App extends React.Component {
    render() {
        return (<SparklineComponent id='sparkline' height='200px' width='350px' containerArea={{
                border: { color: '#033e96', width: 2 }
            }} 
        // To render sparkline with padding
        padding={{ left: 20, right: 20, bottom: 20, top: 20 }} border={{
                color: '#033e96', width: 1
            }} type='Area' fill='#b2cfff' dataSource={[3, 6, 4, 1, 3, 2, 5]}>
        </SparklineComponent>);
    }
}
ReactDOM.render(<App />, document.getElementById('sparkline'));
import * as React from 'react';
import * as ReactDOM from "react-dom";
import { SparklineComponent } from '@syncfusion/ej2-react-charts';

function App() {

  return ( <SparklineComponent id='sparkline'
    height='200px' width='350px'
    containerArea= { {
        border: { color: '#033e96', width: 2 }
    }}
    // To render sparkline with padding
    padding= { { left: 20, right: 20, bottom: 20, top: 20} }
    border= { {
        color: '#033e96', width: 1
    }}
    type= 'Area'
    fill= '#b2cfff'
    dataSource={[ 3, 6, 4, 1, 3, 2, 5]}>
</SparklineComponent> );

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

Sparkline area customization

The background color of the sparkline area can be customized using the containerArea background color. By default, the sparkline background color is transparent.

import * as React from 'react';
import * as ReactDOM from "react-dom";
import { SparklineComponent } from '@syncfusion/ej2-react-charts';
export class App extends React.Component {
    render() {
        return (<SparklineComponent id='sparkline' height='200px' width='350px' containerArea={{
                border: { color: '#033e96', width: 2 },
                // To render sparkline with background
                background: '#eff1f4',
            }} padding={{ left: 20, right: 20, bottom: 20, top: 20 }} border={{
                color: '#033e96', width: 1
            }} type='Area' fill='#b2cfff' dataSource={[3, 6, 4, 1, 3, 2, 5]}>
        </SparklineComponent>);
    }
}
ReactDOM.render(<App />, document.getElementById('sparkline'));
import * as React from 'react';
import * as ReactDOM from "react-dom";
import { SparklineComponent } from '@syncfusion/ej2-react-charts';

function App() {

  return ( <SparklineComponent id='sparkline'
    height='200px' width='350px'
    containerArea= { {
        border: { color: '#033e96', width: 2 },
        // To render sparkline with background
        background: '#eff1f4',
    }}
    padding= { { left: 20, right: 20, bottom: 20, top: 20} }
    border= { {
        color: '#033e96', width: 1
    }}
    type= 'Area'
    fill= '#b2cfff'
    dataSource={[ 3, 6, 4, 1, 3, 2, 5]}>
</SparklineComponent> );

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

Sparkline theme

Datalabel and track line colors of the sparkline will be changed based on theme. For example, for dark theme, the color of datalabel and track line should be white; for light theme, their value should be black. The possible values for sparkline theme are Material, Fabric, Bootstrap, and Highcontrast.

The following code example shows the color for datalabel and track line is set to white for dark theme.

import * as React from 'react';
import * as ReactDOM from "react-dom";
import { SparklineComponent, Inject, SparklineTooltip } from '@syncfusion/ej2-react-charts';
export class App extends React.Component {
    render() {
        return (<SparklineComponent id='sparkline' height='200px' width='350px' 
        // To specify theme
        theme='Highcontrast' dataLabelSettings={{ visible: ['All'] }} tooltipSettings={{
                trackLineSettings: { visible: true }
            }} axisSettings={{
                minX: -1, maxX: 7
            }} lineWidth={3} border={{
                color: 'transparent', width: 2
            }} type='Line' fill='#007dd1' dataSource={[3, 6, 4, 1, 3, 2, 5]}>
    <Inject services={[SparklineTooltip]}/>
        </SparklineComponent>);
    }
}
ReactDOM.render(<App />, document.getElementById('sparkline'));
import * as React from 'react';
import * as ReactDOM from "react-dom";
import { SparklineComponent, Inject, SparklineTooltip } from '@syncfusion/ej2-react-charts';

function App() {

  return ( <SparklineComponent id='sparkline'
    height='200px' width='350px'
    // To specify theme
    theme= 'Highcontrast'
    dataLabelSettings= { { visible: ['All'] }}
    tooltipSettings= { {
        trackLineSettings: { visible: true }
    }}
    axisSettings= { {
        minX: -1, maxX: 7
    }}
    lineWidth= { 3 }
    border= { {
        color: 'transparent', width: 2
    }}
    type= 'Line'
    fill= '#007dd1'
    dataSource={[ 3, 6, 4, 1, 3, 2, 5]}>
    <Inject services={[SparklineTooltip]} />
</SparklineComponent> );

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