How to change the data marker symbol type in React Chart?

This article explains how to change the data marker symbol type in the React Chart.

Customize the data marker shape

You can easily change the marker shapes by using the shape property. Available shapes are Circle, Rectangle, Triangle, Diamond, Cross, Plus, HorizontalLine, VerticalLine, Pentagon, InvertedTriangle, and Image.

In the following code example, the diamond shape is used for marker.

Index.js

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

const Line = () => {
return (
    <ChartComponent id="charts">
      <Inject services={[LineSeries, Category, Tooltip, Highlight]} />
      <SeriesCollectionDirective>
        <SeriesDirective
          dataSource={data}
          xName="x"
          yName="y"
          width={2}
          marker={{
            visible: true,
            width: 12,
            height: 12,
            shape: 'Diamond',
            isFilled: true,
            fill: 'red',
            border: { width: 0 }
          }}
          type="Line"
          fill="orange"
        ></SeriesDirective>
      </SeriesCollectionDirective>
    </ChartComponent>
   );
};
export default Line;
