This article explains how to replace the axis labels with image in the React Chart.

Customize the axis labels with image

Annotations are used to mark the specific area of interest in the chart area with texts, shapes or images.

You can replace the axis labels with image by using the annotations option. By using the content option of annotation object, you can specify the class of the element that needs to be displayed in the chart area.

In the following code example, the primary x axis labels are replaced with an image.

Index.js

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

const Column = () => {
return (
     <ChartComponent
       id="charts"
       primaryXAxis={{
         valueType: 'Category',
         interval: 1,
         labelPlacement: 'OnTicks',
         labelPosition: 'Inside'
       }}
       primaryYAxis={{
         minimum: 0,
         maximum: 80,
         interval: 10
       }}
     >
       <Inject services={[ColumnSeries, Category, ChartAnnotation]} />
       <AnnotationsDirective>
         <AnnotationDirective
           content='<div class="fa fa-bicycle" style="font-size:22px;color:blue"></div>'
           x="Sedan"
           y={3}
           coordinateUnits="Point"
         ></AnnotationDirective>
         <AnnotationDirective
           content='<div class="fa fa-car" style="font-size:20px;color:blue"></div>'
           x="MUV"

           y={3}
           coordinateUnits="Point"
         ></AnnotationDirective>
       </AnnotationsDirective>
       <SeriesCollectionDirective>
         <SeriesDirective
           dataSource={data}
           xName="x"
           yName="y"
           fill="#febe17"
