How to set the opacity of the React Chart?

This article explains how to set the opacity of the React Chart.

Customize the opacity of the series

You can easily customize the opacity of the series by using the opacity property. By default, the opacity of the chart series is 1.

In the following code example, the opacity of the series is set to 0.5 and the series fill is set to green.

Index.js

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

const Spline = () => {
return (
    <ChartComponent
      id="charts"
    >
      <Inject services={[SplineAreaSeries, Category, Tooltip]} />
      <SeriesCollectionDirective>
        <SeriesDirective
          dataSource={data1}
          xName="x"
          yName="y"
          type="SplineArea"
          fill="green"
          border={{ width: 2, color: 'black' }}
          opacity={0.5}
        />
      </SeriesCollectionDirective>
    </ChartComponent>
   );
};
export default Spline;

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