Line Chart in React Charts

3 Feb 202624 minutes to read

Line

To render a line series in your chart, you need to follow a few steps to configure it correctly. Here’s a concise guide on how to do this:

  1. Set the series type: Define the series type as Line in your chart configuration. This indicates that the data should be represented as a line chart, which is ideal for visualizing trends over time or across categories.

  2. Inject the LineSeries module: Inject LineSeries module into the services. This step is essential, as it ensures that the necessary functionalities for rendering line series are available in your chart.

import * as React from "react";
import * as ReactDOM from "react-dom";
import { ChartComponent, SeriesCollectionDirective, SeriesDirective, Inject, Legend, Category, Tooltip, DataLabel, LineSeries } from '@syncfusion/ej2-react-charts';
import { data } from './datasource';
function App() {
    return <ChartComponent id='charts'>
      <Inject services={[LineSeries, Legend, Tooltip, DataLabel, Category]}/>
      <SeriesCollectionDirective>
        <SeriesDirective dataSource={data} xName='x' yName='y' width={2} name='India' type='Line'>
        </SeriesDirective>
      </SeriesCollectionDirective>
    </ChartComponent>;
}
;
export default App;
ReactDOM.render(<App />, document.getElementById("charts"));
import * as React from "react";
import * as ReactDOM from "react-dom";
import { ChartComponent, SeriesCollectionDirective, SeriesDirective, Inject,
         Legend, Category, Tooltip, DataLabel, Zoom, Crosshair, LineSeries, Selection}
from'@syncfusion/ej2-react-charts';
import { data } from './datasource';

function App() {

  
    return <ChartComponent id='charts'>
      <Inject services={[LineSeries, Legend, Tooltip, DataLabel, Category]} />
      <SeriesCollectionDirective>
        <SeriesDirective dataSource={data} xName='x' yName='y' width={2} name='India' type='Line'>
        </SeriesDirective>
      </SeriesCollectionDirective>
    </ChartComponent>

};
export default App;
ReactDOM.render(<App />, document.getElementById("charts"));
export let data = [
    { x: 2005, y: 28 }, 
    { x: 2006, y: 25 }, 
    { x: 2007, y: 26 }, 
    { x: 2008, y: 27 },
    { x: 2009, y: 32 }, 
    { x: 2010, y: 35 }, 
    { x: 2011, y: 30 }
];
export let data: Object[] = [
    { x: 2005, y: 28 }, 
    { x: 2006, y: 25 }, 
    { x: 2007, y: 26 }, 
    { x: 2008, y: 27 },
    { x: 2009, y: 32 }, 
    { x: 2010, y: 35 }, 
    { x: 2011, y: 30 }
];

Binding data with series

You can bind data to the chart using the dataSource property within the series configuration. This allows you to connect a JSON dataset or remote data to your chart. To display the data correctly, map the fields from the data to the chart series xName and yName properties.

import * as React from "react";
import * as ReactDOM from "react-dom";
import { ChartComponent, SeriesCollectionDirective, SeriesDirective, Inject, Legend, Category, Tooltip, DataLabel, LineSeries } from '@syncfusion/ej2-react-charts';
import { data } from './datasource';
function App() {
    return <ChartComponent id='charts'>
      <Inject services={[LineSeries, Legend, Tooltip, DataLabel, Category]}/>
      <SeriesCollectionDirective>
        <SeriesDirective dataSource={data} xName='x' yName='y' width={2} name='India' type='Line'>
        </SeriesDirective>
      </SeriesCollectionDirective>
    </ChartComponent>;
}
;
export default App;
ReactDOM.render(<App />, document.getElementById("charts"));
import * as React from "react";
import * as ReactDOM from "react-dom";
import { ChartComponent, SeriesCollectionDirective, SeriesDirective, Inject,
         Legend, Category, Tooltip, DataLabel, Zoom, Crosshair, LineSeries, Selection}
from'@syncfusion/ej2-react-charts';
import { data } from './datasource';

function App() {

  
    return <ChartComponent id='charts'>
      <Inject services={[LineSeries, Legend, Tooltip, DataLabel, Category]} />
      <SeriesCollectionDirective>
        <SeriesDirective dataSource={data} xName='x' yName='y' width={2} name='India' type='Line'>
        </SeriesDirective>
      </SeriesCollectionDirective>
    </ChartComponent>

};
export default App;
ReactDOM.render(<App />, document.getElementById("charts"));
export let data = [
    { x: 2005, y: 28 }, 
    { x: 2006, y: 25 }, 
    { x: 2007, y: 26 }, 
    { x: 2008, y: 27 },
    { x: 2009, y: 32 }, 
    { x: 2010, y: 35 }, 
    { x: 2011, y: 30 }
];
export let data: Object[] = [
    { x: 2005, y: 28 }, 
    { x: 2006, y: 25 }, 
    { x: 2007, y: 26 }, 
    { x: 2008, y: 27 },
    { x: 2009, y: 32 }, 
    { x: 2010, y: 35 }, 
    { x: 2011, y: 30 }
];

Series customization

The following properties can be used to customize the line series.

Fill

The fill property determines the color applied to the series.

import * as React from "react";
import * as ReactDOM from "react-dom";
import { ChartComponent, SeriesCollectionDirective, SeriesDirective, Inject, Legend, Category, Tooltip, DataLabel, LineSeries } from '@syncfusion/ej2-react-charts';
import { data } from './datasource';
function App() {
    
    return <ChartComponent id='charts'>
      <Inject services={[LineSeries, Legend, Tooltip, DataLabel, Category]}/>
      <SeriesCollectionDirective>
        <SeriesDirective dataSource={data} xName='x' yName='y' fill='green' name='India' type='Line'>
        </SeriesDirective>
      </SeriesCollectionDirective>
    </ChartComponent>;
}
;
export default App;
ReactDOM.render(<App />, document.getElementById("charts"));
import * as React from "react";
import * as ReactDOM from "react-dom";
import { ChartComponent, SeriesCollectionDirective, SeriesDirective, Inject,
         Legend, Category, Tooltip, DataLabel, Zoom, Crosshair, LineSeries, Selection}
from'@syncfusion/ej2-react-charts';
import { data } from './datasource';

function App() {


  return <ChartComponent id='charts'>
      <Inject services={[LineSeries, Legend, Tooltip, DataLabel, Category]} />
      <SeriesCollectionDirective>
        <SeriesDirective dataSource={data} xName='x' yName='y' fill='green' type='Line'>
        </SeriesDirective>
      </SeriesCollectionDirective>
    </ChartComponent>
  
};
export default App;
ReactDOM.render(<App />, document.getElementById("charts"));
export let data = [
    { x: 2005, y: 28 }, 
    { x: 2006, y: 25 },
    { x: 2007, y: 26 }, 
    { x: 2008, y: 27 },
    { x: 2009, y: 32 }, 
    { x: 2010, y: 35 }, 
    { x: 2011, y: 30 }
];
export let data: Object[] = [
    { x: 2005, y: 28 }, 
    { x: 2006, y: 25 },
    { x: 2007, y: 26 }, 
    { x: 2008, y: 27 },
    { x: 2009, y: 32 }, 
    { x: 2010, y: 35 }, 
    { x: 2011, y: 30 }
];

The fill property can be used to apply a gradient color to the line series. By configuring this property with gradient values, you can create a visually appealing effect in which the color transitions smoothly from one shade to another.

import * as React from "react";
import * as ReactDOM from "react-dom";
import { ChartComponent, SeriesCollectionDirective, SeriesDirective, Inject, Legend, Category, Tooltip, DataLabel, LineSeries } from '@syncfusion/ej2-react-charts';
import { data } from './datasource';
function App() {
    return <ChartComponent id='charts'>
      <Inject services={[LineSeries, Legend, Tooltip, DataLabel, Category]}/>
      <SeriesCollectionDirective>
        <SeriesDirective dataSource={data} xName='x' yName='y' fill='url(#gradient)' type='Line'>
        </SeriesDirective>
      </SeriesCollectionDirective>
    </ChartComponent>;
}
;
export default App;
ReactDOM.render(<App />, document.getElementById("charts"));
import * as React from "react";
import * as ReactDOM from "react-dom";
import { ChartComponent, SeriesCollectionDirective, SeriesDirective, Inject,
         Legend, Category, Tooltip, DataLabel, Zoom, Crosshair, LineSeries, Selection}
from'@syncfusion/ej2-react-charts';
import { data } from './datasource';

function App() {
  return <ChartComponent id='charts'>
      <Inject services={[LineSeries, Legend, Tooltip, DataLabel, Category]} />
      <SeriesCollectionDirective>
        <SeriesDirective dataSource={data} xName='x' yName='y' fill='url(#gradient)' type='Line'>
        </SeriesDirective>
      </SeriesCollectionDirective>
    </ChartComponent>
  
};
export default App;
ReactDOM.render(<App />, document.getElementById("charts"));
export let data = [
    { x: 2005, y: 28 }, 
    { x: 2006, y: 25 },
    { x: 2007, y: 26 }, 
    { x: 2008, y: 27 },
    { x: 2009, y: 32 }, 
    { x: 2010, y: 35 }, 
    { x: 2011, y: 30 }
];
export let data: Object[] = [
    { x: 2005, y: 28 }, 
    { x: 2006, y: 25 },
    { x: 2007, y: 26 }, 
    { x: 2008, y: 27 },
    { x: 2009, y: 32 }, 
    { x: 2010, y: 35 }, 
    { x: 2011, y: 30 }
];

Multicolored Line

To render a multicolored line series in your chart, you need to follow a few steps to configure it correctly. Here’s a concise guide on how to do this:

  1. Set the series type: Define the series type as MultiColoredLine in your chart configuration. This specifies that the series should be rendered as a multicolored line chart, with different segments of the line having distinct colors.

  2. Inject the MultiColoredLineSeries module: Inject LineSeries module into the services. This step is essential, as it ensures that the necessary functionalities for rendering line series are available in your chart.

  3. Map individual colors: Utilize the pointColorMapping property to assign individual colors to each data point. This allows you to customize the color of each segment of the line based on your data.

Events

Series render

The seriesRender event enables modification of series properties (for example, data, fill, or name) immediately before rendering. Use this event to adjust series appearance or to dynamically swap data sources.

import * as React from "react";
import * as ReactDOM from "react-dom";
import { ChartComponent, SeriesCollectionDirective, SeriesDirective, Inject, Legend, Category, Tooltip, DataLabel, LineSeries } from '@syncfusion/ej2-react-charts';
import { data } from './datasource';
function App() {
  const seriesRender = (args) => {
    args.fill = '#ff6347';
  };
  const marker = {
    visible: true,
    width: 10,
    height: 10,
    border: { width: 2, color: '#F8AB1D' },
  };

    return <ChartComponent id='charts' seriesRender={seriesRender}>
      <Inject services={[LineSeries, Legend, Tooltip, DataLabel, Category]}/>
      <SeriesCollectionDirective>
        <SeriesDirective dataSource={data} xName='x' yName='y' type='Line' marker={marker}>
        </SeriesDirective>
      </SeriesCollectionDirective>
    </ChartComponent>;

Point render

The pointRender event provides a hook to customize each data point (for example, marker shape, border, or fill) before it is drawn. Use this to apply per-point styling rules or conditional formatting.

import * as React from "react";
import * as ReactDOM from "react-dom";
import { ChartComponent, SeriesCollectionDirective, SeriesDirective, Inject, Legend, Category, Tooltip, DataLabel, LineSeries } from '@syncfusion/ej2-react-charts';

function App() {
  const pointRender = (args) => {
    if (args.point.index % 2 !== 0) {
      args.fill = '#ff6347';
  }
  else {
      args.fill = '#009cb8';
  }
  };
  const marker = {
    visible: true,
    width: 10,
    height: 10,
    border: { width: 2, color: '#F8AB1D' },
  };

    return <ChartComponent id='charts' pointRender={pointRender}>
      <Inject services={[LineSeries, Legend, Tooltip, DataLabel, Category]}/>
      <SeriesCollectionDirective>
        <SeriesDirective dataSource={data} xName='x' yName='y' type='Line' marker={marker}>
