How to select the series through legend?

This article explains how to select the series through the legend in the React Chart.

Select the series through legend

The series visibility collapses based on the legend visibility. By default, legend click enables you to collapse the series visibility. On other hand, if you need to select a series through legend click, disable the toggleVisibility. By using the selection, you need to specify the selectionMode.

In the following code example, the toggle visibility is disabled.

Index.js

import { createRoot } from 'react-dom/client';
import * as React from 'react';
import { ChartComponent, SeriesCollectionDirective, Highlight, SeriesDirective, Inject, Legend, Category, LineSeries,
 Tooltip, Selection } from '@syncfusion/ej2-react-charts';
 
const Line = () => {
 return (
       <ChartComponent
         id="charts"
         primaryXAxis={{
           interval: 1,
           valueType: 'Category'
         }}
         primaryYAxis={{
           minimum: 0,
           maximum: 400,
           interval: 100,
           labelFormat: '${value}'
         }}
         legendSettings={{
           visible: true,
           enableHighlight: true,
           toggleVisibility: false
         }}
         title="Family Expenses for Year"
         tooltip={{ enable: true }}
         selectionMode="Series"
       >
         <Inject
           services={[ LineSeries, Category, Legend, Tooltip, Highlight, Selection ]}
         />
         <SeriesCollectionDirective>
           <SeriesDirective
             dataSource={chartData}
             xName="x"
             yName="y"
             name="John"
             type="Line"
           />
           <SeriesDirective
             dataSource={chartData}
             xName="x"
             yName="y1"
             name="Peter"
             type="Line"
           />
         </SeriesCollectionDirective>
       </ChartComponent>
   );
};
export default Line;

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