How to show tooltip when clicking the axis label of React Chart?

This article explains how to display a tooltip when clicking the axis label in a React Chart.

Customize the chart to display a tooltip when clicking the axis label

You can programmatically show the tooltip image by clicking the axis label using the axisLabelClick event and the showTooltip method. Also, set the enable property to true in the tooltip.

You can also utilize the template property to customize the appearance of the tooltip, including showing an image.

In the following code example, the tooltip image is displayed when clicking the axis label.

Index.js

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

const Column = () => {
let template =
'<div id="chart_cloud"><img src="https://ej2.syncfusion.com/react/demos/src/chart/images/cloud.png" style="width: 41px; height: 41px"/></div>';

const axisLabelClick = (args) => {
  let x = args.chart.series[0].points[args.index].x;
  let y = args.chart.series[0].points[args.index].y;
  args.chart.showTooltip(x, y, true);
};
return (
  <ChartComponent
    id="charts"
    legendSettings={{ enableHighlight: true }}
    primaryXAxis={{
      valueType: 'Category',
      interval: 1
    }}
    primaryYAxis={{
      maximum: 10,
      interval: 2,
      labelFormat: '{value}°C'
    }}
    tooltip={{
      enable: true,
      template: template
    }}
    title="Weather Report"
    axisLabelClick={axisLabelClick.bind(this)}
  >
    <Inject services={[ColumnSeries, Tooltip, Category]} />
    <SeriesCollectionDirective>
      <SeriesDirective
        dataSource={data}
        xName="x"
        columnSpacing={0.1}
        yName="y"
        type="Column"
      />
    </SeriesCollectionDirective>
  </ChartComponent>
);
};
export default Column;

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