How to display the modified axis labels in React Chart?

This article explains how to display the modified axis labels in the React Chart.

Customize the axis labels

Axis labels in the chart are generated based on the provided data points. In cases where you need to customize the UI by replacing the automatically generated labels with your desired text, you can achieve this by modifying the content in the axisLabelRender event at the desired index.

In the following code example, the primary y-axis labels are changed using the event.

Index.js

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

const Line = () => {
 const axisLabelRender = (args) => {
   if (args.axis.orientation === 'Vertical') 
   {
     if (args.value === 1.6) {
       args.text = 'Low';
     } else if (args.value === 2.1000000000000005) {
       args.text = 'Average';
     } else if (args.value === 2.6) {
       args.text = 'High';
     }
   }
 }
 return (
       <ChartComponent
         id="charts"
         primaryXAxis={{
           valueType: 'Category',
           labelPlacement: 'OnTicks',
           interval: 2
         }}
         primaryYAxis={{
           minimum: 1.6,
           maximum: 2.6,
           interval: 0.1
         }}
         title="USA Wheat Production"
         axisLabelRender={axisLabelRender.bind(this)}
       >
         <Inject
           services={[LineSeries, Tooltip, Category]}
         />
         <SeriesCollectionDirective>
           <SeriesDirective
             dataSource={data}
             xName="x"
             yName="y"
             marker={{
               visible: true,
               isFilled: true
             }}
             type="Line"
           ></SeriesDirective>
         </SeriesCollectionDirective>
       </ChartComponent>
   );
};
export default Line;

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