How to display other information in React Chart data label?

This article explains how to display other information in the data label in the React Chart.

Customize the display of additional information in the data label

You can easily display additional information along with the data label by using the name property. By default, the data label shows the y value in the datasource.

In the following code example, the data label is displayed with additional information on the x value using the name property.

Index.js

import { createRoot } from 'react-dom/client';
import * as React from 'react';
import { Browser } from '@syncfusion/ej2-base';
import { AccumulationChartComponent, AccumulationSeriesCollectionDirective, AccumulationSeriesDirective,
 Inject, AccumulationLegend, PieSeries, AccumulationDataLabel } from '@syncfusion/ej2-react-charts';
 
export let data = [
  { x: 'David', y: 180, text: 'David: 180' },
  { x: 'Micheal', y: 170, text: 'Micheal: 170' },
  { x: 'Steve', y: 160, text: 'Steve: 160' },
  { x: 'Joel', y: 182, text: 'Joel: 182' }
];

const Pie = () => {
 return (
       <AccumulationChartComponent
         id="pie-chart"
         legendSettings={{ visible: true, position: 'Bottom' }}
       >
         <Inject
           services={[AccumulationLegend, PieSeries, AccumulationDataLabel]}
         />
         <AccumulationSeriesCollectionDirective>
           <AccumulationSeriesDirective
             dataSource={data}
             xName="x"
             yName="y"
             startAngle={Browser.isDevice ? 55 : 90}
             dataLabel={{
               visible: true,
               position: 'Inside',
               name: 'text',
               font: { fontWeight: '600', color: '#ffffff' },
               connectorStyle: { length: '20px', type: 'Curve' }
             }}
             radius={Browser.isDevice ? '40%' : '80%'}
             legendShape="Circle"
           />
         </AccumulationSeriesCollectionDirective>
       </AccumulationChartComponent>
   );
};
export default Pie;

const root = createRoot(document.getElementById('sample'));
root.render(<Pie />);
