How to show the trackball on load time in React Chart?

This article explains how to display the trackball at load time in the React Chart.

Customize the settings to show the trackball on load time in the chart

To enable the trackball, set the enable property of the crosshair to true, and the shared property in the tooltip to true in the chart. Alternatively, you can show the trackball programmatically during the chart loading time using the loaded event and the showTooltip and showCrosshair methods.

In the following code example, the trackball is shown during chart rendering.

Index.js

import { createRoot } from 'react-dom/client';
import * as React from 'react';
import { ChartComponent, SeriesCollectionDirective, SeriesDirective, Inject, LineSeries, DateTime,
Tooltip, Crosshair } from '@syncfusion/ej2-react-charts';
import { john, andrew, thomas } from './trackball-data';

const TrackballChart = () => {
 const onChartLoad = (args) => {
     args.chart.showTooltip(200, 200, false);
     args.chart.showCrosshair(200, 200);
 };
return (
     <chartcomponent id="charts" primaryxaxis="{{" minimum:="" new="" date(2000,="" 1,="" 1),="" maximum:="" date(2006,="" 2,="" 11),="" valuetype:="" 'datetime',="" skeleton:="" 'y',="" crosshairtooltip:="" {="" enable:="" true="" }="" }}="" primaryyaxis="{{" title:="" 'revenue="" (in="" million)',="" labelformat:="" '{value}m',="" 10,="" 80="" title="Average Sales per Person" loaded="{onChartLoad.bind(this)}" tooltip="{{" true,="" shared:="" format:="" '${point.y}',="" enablemarker:="" false,="" header:="" ''="" crosshair="{{" linetype:="" 'vertical'="">

       </seriesdirective></seriesdirective></seriesdirective></seriescollectiondirective>
     </inject></chartcomponent>
  );
};
export default TrackballChart;

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