How to add benchmark line in React Chart?

This article explains how to add a benchmark line in the React Chart.

Customize to include a benchmark line

The React chart supports strip lines in both horizontal and vertical orientations, and it allows for customization of the strip line in both directions.

To create a horizontal stripline, add it to the vertical axis and set the visible option to true. For a vertical stripline, add it to the horizontal axis and also set the visible option to true. Striplines are rendered within the specified start to end range, and multiple striplines can be added to an axis.

You can easily represent a benchmark line in a chart using the annotation and stripline and set the target value to the stripline start range.

In the following code example, the chart includes a benchmark line annotated at 62%.

Index.js

import { createRoot } from 'react-dom/client';
import * as React from 'react';
import { ChartComponent, SeriesCollectionDirective, SeriesDirective, Inject, Category, ColumnSeries, StripLine, ChartAnnotation,
AnnotationsDirective, AnnotationDirective, DataLabel } from '@syncfusion/ej2-react-charts';

let content =
'<div style="font-weight: bold; color: #24748b; font-size: 12px;">Benchmark</div>';

const Column = () => {
return (
  <ChartComponent
    id="charts"
    primaryXAxis={{
      valueType: 'Category',
      interval: 1
    }}
    primaryYAxis={{
      maximum: 80,
      interval: 10,
      labelFormat: '{value}%',
      stripLines: [
        {
          start: 62,
          size: 1,
          color: '#f8a509',
          visible: true,
          horizontalAlignment: 'Start',
          zIndex: 'Over'
        }
      ]
    }}
  >
    <Inject
      services={[ ColumnSeries, Category, StripLine, ChartAnnotation, DataLabel ]}
    />
    <AnnotationsDirective>
      <AnnotationDirective
        content={content}
        region="Series"
        x="12%"
        y="25%"
      ></AnnotationDirective>
    </AnnotationsDirective>
    <SeriesCollectionDirective>
      <SeriesDirective
        dataSource={data}
        xName="x"
        yName="y"
        type="Column"
        marker={{
          dataLabel: {
            visible: true,
            position: 'Top',
            font: { fontWeight: '600', color: '#ffffff' }
          },
        }}
      />
    </SeriesCollectionDirective>
  </ChartComponent>
);
};
export default Column;

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