Bar Charts in React Chart component

14 Oct 202424 minutes to read

Bar

To render a bar 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 Bar in your chart configuration. This indicates that the data should be represented as a bar chart, which makes it easy to compare values across categories.

  2. Inject the BarSeries module: Inject the BarSeries module into the services. This step is essential, as it ensures that the necessary functionalities for rendering bar 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, BarSeries } from '@syncfusion/ej2-react-charts';
import { data } from './datasource';
function App() {
    const primaryxAxis = { minimum: 2005, maximum: 2012, interval: 1, title: 'Year' };
    const primaryyAxis = {
        title: 'Percentage',
        labelFormat: '{value}%'
    };
    return <ChartComponent id='charts' primaryXAxis={primaryxAxis} primaryYAxis={primaryyAxis} title='Unemployment rate (%)'>
      <Inject services={[BarSeries, Legend, Tooltip, DataLabel, Category]}/>
      <SeriesCollectionDirective>
        <SeriesDirective dataSource={data} xName='x' yName='y' name='India' type='Bar'>
        </SeriesDirective>
      </SeriesCollectionDirective>
    </ChartComponent>;
}
;
export default App;
ReactDOM.render(<App />, document.getElementById("charts"));
import * as React from "react";
import * as ReactDOM from "react-dom";
import { AxisModel, ChartComponent, SeriesCollectionDirective, SeriesDirective, Inject,
         Legend, Category, Tooltip, DataLabel, Zoom, Crosshair, BarSeries,  Selection}
from'@syncfusion/ej2-react-charts';
import { data } from './datasource';

function App() {

  const primaryxAxis: AxisModel = { minimum: 2005, maximum: 2012, interval: 1, title: 'Year' };
  const primaryyAxis: AxisModel = {
    title: 'Percentage',
    labelFormat: '{value}%'
  };

  return <ChartComponent id='charts'
      primaryXAxis={primaryxAxis}
      primaryYAxis={primaryyAxis}
      title='Unemployment rate (%)'>
      <Inject services={[BarSeries, Legend, Tooltip, DataLabel, Category]} />
      <SeriesCollectionDirective>
        <SeriesDirective dataSource={data} xName='x' yName='y' name='India' type='Bar'>
        </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, BarSeries } from '@syncfusion/ej2-react-charts';
import { data } from './datasource';
function App() {
    const primaryxAxis = { minimum: 2005, maximum: 2012, interval: 1, title: 'Year' };
    const primaryyAxis = {
        title: 'Percentage',
        labelFormat: '{value}%'
    };
    return <ChartComponent id='charts' primaryXAxis={primaryxAxis} primaryYAxis={primaryyAxis} title='Unemployment rate (%)'>
      <Inject services={[BarSeries, Legend, Tooltip, DataLabel, Category]}/>
      <SeriesCollectionDirective>
        <SeriesDirective dataSource={data} xName='x' yName='y' name='India' type='Bar'>
        </SeriesDirective>
      </SeriesCollectionDirective>
    </ChartComponent>;
}
;
export default App;
ReactDOM.render(<App />, document.getElementById("charts"));
import * as React from "react";
import * as ReactDOM from "react-dom";
import { AxisModel, ChartComponent, SeriesCollectionDirective, SeriesDirective, Inject,
         Legend, Category, Tooltip, DataLabel, Zoom, Crosshair, BarSeries,  Selection}
from'@syncfusion/ej2-react-charts';
import { data } from './datasource';

function App() {

  const primaryxAxis: AxisModel = { minimum: 2005, maximum: 2012, interval: 1, title: 'Year' };
  const primaryyAxis: AxisModel = {
    title: 'Percentage',
    labelFormat: '{value}%'
  };

  return <ChartComponent id='charts'
      primaryXAxis={primaryxAxis}
      primaryYAxis={primaryyAxis}
      title='Unemployment rate (%)'>
      <Inject services={[BarSeries, Legend, Tooltip, DataLabel, Category]} />
      <SeriesCollectionDirective>
        <SeriesDirective dataSource={data} xName='x' yName='y' name='India' type='Bar'>
        </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 bar 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, BarSeries } from '@syncfusion/ej2-react-charts';

function App() {
    const primaryxAxis = { minimum: 2005, maximum: 2012, interval: 1, title: 'Year' };
    const primaryyAxis = {
        minimum: 3, maximum: 12, interval: 1, title: 'Percentage',
        labelFormat: '{value}%'
    };
    return <ChartComponent id='charts' primaryXAxis={primaryxAxis} primaryYAxis={primaryyAxis} title='Unemployment rate (%)'>
      <Inject services={[BarSeries, Legend, Tooltip, DataLabel, Category]}/>
      <SeriesCollectionDirective>
        <SeriesDirective dataSource={customData} xName='x' yName='y' type='Bar' fill='red'>
        </SeriesDirective>
      </SeriesCollectionDirective>
    </ChartComponent>;
}
;
export default App;
ReactDOM.render(<App />, document.getElementById("charts"));
import * as React from "react";
import * as ReactDOM from "react-dom";

         Legend, Category, Tooltip, DataLabel, Zoom, Crosshair, BarSeries,  Selection}
from'@syncfusion/ej2-react-charts';
import { customData } from './datasource';

function App() {

  const primaryxAxis: AxisModel = { minimum: 2005, maximum: 2012, interval: 1, title: 'Year' };
  const primaryyAxis: AxisModel = {
    minimum: 3, maximum: 12, interval: 1, title: 'Percentage',
    labelFormat: '{value}%'
  };

  return <ChartComponent id='charts'
      primaryXAxis={primaryxAxis}
      primaryYAxis={primaryyAxis}
      title='Unemployment rate (%)'>
      <Inject services={[BarSeries, Legend, Tooltip, DataLabel, Category]} />
      <SeriesCollectionDirective>
        <SeriesDirective dataSource={customData} xName='x' yName='y' type='Bar' fill='red'>
        </SeriesDirective>
      </SeriesCollectionDirective>
    </ChartComponent>

};
export default App;
ReactDOM.render(<App />, document.getElementById("charts"));
export let customData = [
    { x: 2006, y: 7.8,  point: 'red' },
    { x: 2007, y: 7.2,  point: 'green' },
    { x: 2008, y: 6.8,  point: 'orange' },
    { x: 2009, y: 10.7, point: 'yellow' },
    { x: 2010, y: 10.8, point: 'grey' },
    { x: 2011, y: 9.8,  point: 'blue' }
];
export let customData: Object[] = [

    { x: 2010, y: 10.8, point: 'grey' },
    { x: 2011, y: 9.8,  point: 'blue' }
];

The fill property can be used to apply a gradient color to the bar 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.

Opacity

The opacity property specifies the transparency level of the fill. Adjusting this property allows you to control how opaque or transparent the fill color of the series appears.

Empty points

Data points with null or undefined values are considered empty. Empty data points are ignored and not plotted on the chart.

Mode

Use the mode property to define how empty or missing data points are handled in the series. The default mode for empty points is Gap.
