Tool tip in React Accumulation chart component

20 Jan 202320 minutes to read

Tooltip for the accumulation chart can be enabled by using the enable property.

index.jsx

import * as React from "react";
import * as ReactDOM from "react-dom";
import { AccumulationChartComponent, AccumulationSeriesCollectionDirective, AccumulationSeriesDirective, AccumulationTooltip, Inject } from '@syncfusion/ej2-react-charts';
import { accData } from 'datasource.ts';
function App() {
    return <AccumulationChartComponent id='charts' tooltip={{ enable: true }}>
      <Inject services={[AccumulationTooltip]}/>
      <AccumulationSeriesCollectionDirective>
        <AccumulationSeriesDirective dataSource={accData} xName='x' yName='y'>
        </AccumulationSeriesDirective>
      </AccumulationSeriesCollectionDirective>
    </AccumulationChartComponent>;
}
;
export default App;
ReactDOM.render(<App />, document.getElementById("charts"));

index.tsx

import * as React from "react";
import * as ReactDOM from "react-dom";
import { AccumulationChartComponent, AccumulationSeriesCollectionDirective, AccumulationSeriesDirective,
 AccumulationTooltip, Inject,TooltipSettingsModel} from'@syncfusion/ej2-react-charts';
import { accData } from 'datasource.ts';

function App() {
  
    return <AccumulationChartComponent id='charts' tooltip={{ enable: true }}>
      <Inject services={[AccumulationTooltip]} />
      <AccumulationSeriesCollectionDirective>
        <AccumulationSeriesDirective dataSource={accData} xName='x' yName='y'>
        </AccumulationSeriesDirective>
      </AccumulationSeriesCollectionDirective>
    </AccumulationChartComponent>

};
export default App;
ReactDOM.render(<App />, document.getElementById("charts"));

Note:To use tooltip feature , we need to inject AccumulationTooltip module into the services.

Header

We can specify header for the tooltip using header property.

index.jsx

import * as React from "react";
import * as ReactDOM from "react-dom";
import { AccumulationChartComponent, AccumulationSeriesCollectionDirective, AccumulationSeriesDirective, AccumulationTooltip, Inject } from '@syncfusion/ej2-react-charts';
import { accData } from 'datasource.ts';
function App() {
    return <AccumulationChartComponent id='charts' tooltip={{ enable: true, header: "Pie Chart" }}>
      <Inject services={[AccumulationTooltip]}/>
      <AccumulationSeriesCollectionDirective>
        <AccumulationSeriesDirective dataSource={accData} xName='x' yName='y'>
        </AccumulationSeriesDirective>
      </AccumulationSeriesCollectionDirective>
    </AccumulationChartComponent>;
}
;
export default App;
ReactDOM.render(<App />, document.getElementById("charts"));

index.tsx

import * as React from "react";
import * as ReactDOM from "react-dom";
import { AccumulationChartComponent, AccumulationSeriesCollectionDirective, AccumulationSeriesDirective,
 AccumulationTooltip, Inject }
from'@syncfusion/ej2-react-charts';
import { accData } from 'datasource.ts';

function App() {
  
    return <AccumulationChartComponent id='charts' tooltip={{ enable: true, header: "Pie Chart" }}>
      <Inject services={[AccumulationTooltip]} />
      <AccumulationSeriesCollectionDirective>
        <AccumulationSeriesDirective dataSource={accData} xName='x' yName='y'>
        </AccumulationSeriesDirective>
      </AccumulationSeriesCollectionDirective>
    </AccumulationChartComponent>

};
export default App;
ReactDOM.render(<App />, document.getElementById("charts"));

Format

By default, tooltip shows information of x and y value in points. In addition to that, you can show more information in tooltip. For example the format ${series.name} ${point.x} shows series name and point x value.

index.jsx

import * as React from "react";
import * as ReactDOM from "react-dom";
import { AccumulationChartComponent, AccumulationSeriesCollectionDirective, AccumulationSeriesDirective, AccumulationTooltip, Inject, AccumulationLegend } from '@syncfusion/ej2-react-charts';
import { accData } from 'datasource.ts';
function App() {
    return <AccumulationChartComponent id='charts' tooltip={{ enable: true, format: '${point.x} : <b>${point.y}%</b>' }}>
      <Inject services={[AccumulationLegend, AccumulationTooltip]}/>
      <AccumulationSeriesCollectionDirective>
        <AccumulationSeriesDirective dataSource={accData} xName='x' yName='y'>
        </AccumulationSeriesDirective>
      </AccumulationSeriesCollectionDirective>
    </AccumulationChartComponent>;
}
;
export default App;
ReactDOM.render(<App />, document.getElementById("charts"));

index.tsx

import * as React from "react";
import * as ReactDOM from "react-dom";
import { AccumulationChartComponent, AccumulationSeriesCollectionDirective,
 AccumulationSeriesDirective, AccumulationTooltip, Inject, AccumulationLegend} from'@syncfusion/ej2-react-charts';
import { accData } from 'datasource.ts';

function App() {
  
    return <AccumulationChartComponent id='charts' tooltip={{ enable: true, format: '${point.x} : <b>${point.y}%</b>' }}>
      <Inject services={[AccumulationLegend, AccumulationTooltip]} />
      <AccumulationSeriesCollectionDirective>
        <AccumulationSeriesDirective dataSource={accData} xName='x' yName='y'>
        </AccumulationSeriesDirective>
      </AccumulationSeriesCollectionDirective>
    </AccumulationChartComponent>

};
export default App;
ReactDOM.render(<App />, document.getElementById("charts"));

Tooltip Mapping Name

By default, tooltip shows information of x and y value in points. You can show more information from datasource in tooltip by using the tooltipMappingName property of the tooltip. You can use the ${point.tooltip} as place holders to display the specified tooltip content.

index.jsx

import * as React from "react";
import * as ReactDOM from "react-dom";
import { AccumulationChartComponent, AccumulationSeriesCollectionDirective, AccumulationSeriesDirective, AccumulationTooltip, Inject, AccumulationLegend } from '@syncfusion/ej2-react-charts';
import { accData } from 'datasource.ts';
function App() {
    return <AccumulationChartComponent id='charts' tooltip={{ enable: true, format: '${point.tooltip}' }}>
      <Inject services={[AccumulationLegend, AccumulationTooltip]}/>
      <AccumulationSeriesCollectionDirective>
        <AccumulationSeriesDirective dataSource={accData} xName='x' yName='y' tooltipMappingName='text'>
        </AccumulationSeriesDirective>
      </AccumulationSeriesCollectionDirective>
    </AccumulationChartComponent>;
}
;
export default App;
ReactDOM.render(<App />, document.getElementById("charts"));

index.tsx

import * as React from "react";
import * as ReactDOM from "react-dom";
import { AccumulationChartComponent, AccumulationSeriesCollectionDirective,
 AccumulationSeriesDirective, AccumulationTooltip, Inject, AccumulationLegend}
from'@syncfusion/ej2-react-charts';
import { accData } from 'datasource.ts';

function App() {
  
    return <AccumulationChartComponent id='charts' tooltip={{ enable: true, format: '${point.tooltip}' }}>
      <Inject services={[AccumulationLegend, AccumulationTooltip]} />
      <AccumulationSeriesCollectionDirective>
        <AccumulationSeriesDirective dataSource={accData} xName='x' yName='y' tooltipMappingName='text'>
        </AccumulationSeriesDirective>
      </AccumulationSeriesCollectionDirective>
    </AccumulationChartComponent>

};
export default App;
ReactDOM.render(<App />, document.getElementById("charts"));

Tooltip Template

Any HTML element can be displayed in the tooltip by using the template property.

index.jsx

import * as React from "react";
import * as ReactDOM from "react-dom";
import { AccumulationChartComponent, AccumulationSeriesCollectionDirective, AccumulationSeriesDirective, AccumulationTooltip, Inject } from '@syncfusion/ej2-react-charts';
import { accData } from 'datasource.ts';
function App() {
    const template = chartTemplate;
    function chartTemplate(args) {
        return (<div style={{ border: '1px solid black', backgroundColor: 'red', padding: '2px', float: 'right', lineHeight: '20px', textAlign: 'center' }}>
              <img src='sun_annotation.png'/>
              <div style={{ color: 'blue', padding: '2px', fontSize: '14px', fontStyle: 'medium', fontFamily: 'Roboto', float: 'right', lineHeight: '20px', textAlign: 'center', paddingRight: '6px' }}>
                <span>{args.y}</span>
              </div>
            </div>);
    }
    return <AccumulationChartComponent id='charts' tooltip={{ enable: true, template: template }}>
      <Inject services={[AccumulationTooltip]}/>
      <AccumulationSeriesCollectionDirective>
        <AccumulationSeriesDirective dataSource={accData} xName='x' yName='y'>
        </AccumulationSeriesDirective>
      </AccumulationSeriesCollectionDirective>
    </AccumulationChartComponent>;
}
;
export default App;
ReactDOM.render(<App />, document.getElementById("charts"));

index.tsx

import * as React from "react";
import * as ReactDOM from "react-dom";
import { AccumulationChartComponent, AccumulationSeriesCollectionDirective, AccumulationSeriesDirective,
 AccumulationTooltip, Inject} from'@syncfusion/ej2-react-charts';
import { accData } from 'datasource.ts';

function App() {

  const template:any =chartTemplate;
  function chartTemplate(args:any){
    return (<div style={{ border:'1px solid black', backgroundColor:'red', padding:'2px',float:'right', lineHeight:'20px',textAlign:'center'}}>
              <img src='sun_annotation.png' />
              <div style={{ color:'blue', padding:'2px',fontSize:'14px', fontStyle:'medium',fontFamily:'Roboto' ,float:'right',lineHeight:'20px',textAlign:'center',paddingRight:'6px'}}>
                <span>{args.y}</span>
              </div>
            </div>
          );
  }

  return <AccumulationChartComponent id='charts' tooltip={{ enable: true, template: template }}>
      <Inject services={[AccumulationTooltip]} />
      <AccumulationSeriesCollectionDirective>
        <AccumulationSeriesDirective dataSource={accData} xName='x' yName='y'>
        </AccumulationSeriesDirective>
      </AccumulationSeriesCollectionDirective>
    </AccumulationChartComponent>

};
export default App;
ReactDOM.render(<App />, document.getElementById("charts"));

Customization

The fill and border properties are used to customize the background color and border of the tooltip respectively. The textStyle property in the tooltip is used to customize the font of the tooltip text. The highlightColor property can be used to change the color of the data point when hovering.

index.jsx

import * as React from "react";
import * as ReactDOM from "react-dom";
import { AccumulationChartComponent, AccumulationSeriesCollectionDirective, AccumulationSeriesDirective, AccumulationTooltip, Inject } from '@syncfusion/ej2-react-charts';
import { accData } from 'datasource.ts';
function App() {
    return <AccumulationChartComponent id='charts' tooltip={{
            enable: true, format: '${series.name} ${point.x} : ${point.y}',
            //fill for tooltip
            fill: '#7bb4eb',
            //border for tooltip
            border: {
                width: 2,
                color: 'grey'
            }
        }} highlightColor='red'>
      <Inject services={[AccumulationTooltip]}/>
      <AccumulationSeriesCollectionDirective>
        <AccumulationSeriesDirective dataSource={accData} xName='x' yName='y'>
        </AccumulationSeriesDirective>
      </AccumulationSeriesCollectionDirective>
    </AccumulationChartComponent>;
}
;
export default App;
ReactDOM.render(<App />, document.getElementById("charts"));

index.tsx

import * as React from "react";
import * as ReactDOM from "react-dom";
import { AccumulationChartComponent, AccumulationSeriesCollectionDirective, IAccTooltipRenderEventArgs,
 AccumulationSeriesDirective, AccumulationTooltip, Inject} from'@syncfusion/ej2-react-charts';

    enable: true, format: '${series.name} ${point.x} : ${point.y}',
    //fill for tooltip
    fill: '#7bb4eb',
    //border for tooltip
    border: {
      width: 2,
      color: 'grey'
    }
  }}  highlightColor='red'>
      <Inject services={[AccumulationTooltip]} />
      <AccumulationSeriesCollectionDirective>
        <AccumulationSeriesDirective dataSource={accData} xName='x' yName='y'>
        </AccumulationSeriesDirective>
      </AccumulationSeriesCollectionDirective>
    </AccumulationChartComponent>

};
export default App;
ReactDOM.render(<App />, document.getElementById("charts"));

To customize individual tooltip

Using tooltipRender event, you can customize a tooltip for particular point. event, you can customize a tooltip for particular point.

import { accData } from 'datasource.ts';
function App() {
    const tooltipRender = (args) => {
        if (args.point.index === 3) {
            args.text = args.point.x + '' + ':' + args.point.y + '' + ' ' + 'customtext';
            args.textStyle.color = '#f48042';
        }
    };
    return <AccumulationChartComponent id='charts' tooltip={{ enable: true }} tooltipRender={tooltipRender}>
      <Inject services={[AccumulationLegend, AccumulationTooltip]}/>
      <AccumulationSeriesCollectionDirective>
        <AccumulationSeriesDirective dataSource={accData} xName='x' yName='y'>
