This article explains how to create a dotted forecast line chart in the React Chart.

Customize to create a dotted forecast line chart

You can easily create a dotted forecast line chart by using the dashArray property. The dash array defines the pattern of dashes and gaps to stroke the lines in line type series. By default, it’s an empty string ’ '.

In the following code example, the dash array is set to 5 for the chart series.

Index.js

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

const DashedLine = () => {
 return (
       <ChartComponent
         id="charts"
         primaryXAxis={{
           valueType: 'Category',
           interval: 1,
           labelRotation: -45
         }}
         primaryYAxis={{
           labelFormat: '{value}k',
           minimum: 0,
           maximum: 300,
           interval: 50
         }}
         title="Fruits Production Statistics"
       >
         <Inject
           services={[SplineSeries, Category, Tooltip, Legend, Highlight]}
         />
         <SeriesCollectionDirective>
           <SeriesDirective
             dataSource={data1}
             xName="x"
             yName="y"
             type="Spline"
             name="Actual"
           ></SeriesDirective>
           <SeriesDirective
             dataSource={data2}
             xName="x"
             yName="y"
             dashArray="5"
             type="Spline"
             name="Forecast"
           ></SeriesDirective>
         </SeriesCollectionDirective>
       </ChartComponent>
 );
};
export default DashedLine;

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