How to club data points the React pie charts?

This article explains how to club the React pie data to “Others” category in the React Pie Chart.

How to display the sum of values that are grouped in a React Pie Chart

In the following code example, if the club value is set to 7, points with values less than 7 are grouped together and displayed as a single point with the label Others.

Index.js

import { createRoot } from 'react-dom/client';
import * as React from 'react';
import { Browser } from '@syncfusion/ej2-base';
import { AccumulationChartComponent, AccumulationSeriesCollectionDirective, AccumulationSeriesDirective,
  Inject, PieSeries, AccumulationDataLabel, AccumulationLegend } from '@syncfusion/ej2-react-charts';

const Pie = () => {
  return (
        <AccumulationChartComponent
          id="pie-chart"
          title="Browser Market Share"
          legendSettings={{ visible: true, position: 'Bottom' }}
        >
          <Inject
            services={[PieSeries, AccumulationDataLabel, AccumulationLegend]}
          />
          <AccumulationSeriesCollectionDirective>
            <AccumulationSeriesDirective
              dataSource={data}
              xName="x"
              yName="y"
              explode={true}
              explodeOffset="10%"
              dataLabel={{
                visible: true
              }}
              groupTo="7"
              legendShape="Circle"
            />
          </AccumulationSeriesCollectionDirective>
        </AccumulationChartComponent>
  );
};
export default Pie;

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

How to bind the data labels to the grouped data collection in a React Pie Chart

In the following code example, if the club value is set to 7, points with values less than 7 are grouped together and will display the values present inside the Others group.

Index.js

import { createRoot } from 'react-dom/client';
import * as React from 'react';
import { Browser } from '@syncfusion/ej2-base';
import { AccumulationChartComponent, AccumulationSeriesCollectionDirective, AccumulationSeriesDirective,
Inject, PieSeries, AccumulationDataLabel, AccumulationLegend } from '@syncfusion/ej2-react-charts';

const Pie = () => {
const textRender = (args) => {
 if (args.text.indexOf('Others') != -1) {
   args.text = '';
   for (var i = 0; i < args.series.clubbedPoints.length; i++) {
     args.text = args.text + '<br>' + args.series.clubbedPoints[i].text;
   }
 }
};

return (
     <AccumulationChartComponent
       id="pie-chart"
       title="Browser Market Share"
       legendSettings={{ visible: true, position: 'Bottom' }}
       textRender={textRender.bind(this)}
     >
       <Inject
         services={[PieSeries, AccumulationDataLabel, AccumulationLegend]}
       />
       <AccumulationSeriesCollectionDirective>
         <AccumulationSeriesDirective
           dataSource={data}
           xName="x"
           yName="y"
           explode={true}
           explodeOffset="10%"
           startAngle={Browser.isDevice ? 55 : 35}
           dataLabel={{
             visible: true,
             position: 'Outside',
             name: 'text',
             font: { fontWeight: '600' },
             connectorStyle: { length: '20px', type: 'Curve' }
           }}
           radius={Browser.isDevice ? '40%' : '50%'}
           groupTo="7"
           legendShape="Circle"
         />
       </AccumulationSeriesCollectionDirective>
     </AccumulationChartComponent>
   );
};
export default Pie;

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