How to Pass a JSON array to a React Chart?

This article explains how to pass a JSON array to the React Chart.

Customize the data using JSON

You can link a chart to your dataset by providing a JSON array through the dataSource property in the SeriesDirective. Then, map the JSON fields to the chart axes by assigning them to the xName and yName properties. This enables the chart to render your JSON data effectively.

Example: Pass JSON Data to React Chart

Below is a complete example of how to bind a JSON array to a Column Chart using Syncfusion’s React Chart component.

Index.js

import { createRoot } from 'react-dom/client';
import * as React from 'react';
import { ChartComponent, SeriesCollectionDirective, SeriesDirective, Inject, ColumnSeries, Category
} from '@syncfusion/ej2-react-charts';
import { data } from './data';

const Column = () => {
return (
      <div className="control-section">
       <ChartComponent
         id="charts"
         style={{ textAlign: 'center' }}
         primaryXAxis={{
           valueType: 'Category',
           interval: 1,
           labelPlacement: 'OnTicks',
         }}
         primaryYAxis={{
           minimum: 0,
           maximum: 65,
           interval: 5,
         }}
         chartArea={{ border: { width: 0 } }}
         load={load.bind(this)}
         width={Browser.isDevice ? '100%' : '75%'}
         loaded={loaded.bind(this)}
       >
         <Inject services={[ColumnSeries, Category]} />
         <SeriesCollectionDirective>
           <SeriesDirective
             dataSource={data}
             xName="x"
             yName="y"
             type="Column"
             fill="#febe17"
           />
         </SeriesCollectionDirective>
       </ChartComponent>
     </div>
   );
};
export default Column;

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

JSON data

exports.data = [
 {
   x: 'USA',
   y: 46
 },
 {
   x: 'China',
   y: 36
 },
 {
   x: 'Japan',
   y: 63.5
 },
 {
   x: 'Australia',
   y: 54
 },
 {
   x: 'France',
   y: 50
 }
];
