Tooltip

Tooltip is used to display details about the items in tree map when the mouse hovers over the item.

Default tooltip

By default, tooltip is not visible. You can enable the tooltip by setting the enable property to true and injecting the TreeMapTooltip module using the TreeMap.Inject(TreeMapTooltip).

The following example shows the default tooltip.

App.jsx
import * as React from "react";
import { TreeMapComponent, Inject, TreeMapTooltip } from '@syncfusion/ej2-react-treemap';

export class App extends React.Component {
render() {
  return ( <TreeMapComponent id='treemap'
        dataSource={[
            { fruit:'Apple', count:5000 },
            { fruit:'Mango', count:3000 },
            { fruit:'Orange', count:2300 },
            { fruit:'Banana', count:500 },
            { fruit:'Grape', count:4300 },
            { fruit:'Papaya', count:1200 },
            { fruit:'Melon', count:4500 }
        ]}
        weightValuePath= 'count'
        leafItemSettings= {{
            labelPath: 'fruit'
        }}
        tooltipSettings= {{
            visible: true
        }}>
        <Inject services={[TreeMapTooltip]} />
    </TreeMapComponent> );
 }
}
import * as React from "react";
import { TreeMapComponent, Inject, TreeMapTooltip } from '@syncfusion/ej2-react-treemap';
export class App extends React.Component {
    render() {
        return (<TreeMapComponent id='treemap' dataSource={[
            { fruit: 'Apple', count: 5000 },
            { fruit: 'Mango', count: 3000 },
            { fruit: 'Orange', count: 2300 },
            { fruit: 'Banana', count: 500 },
            { fruit: 'Grape', count: 4300 },
            { fruit: 'Papaya', count: 1200 },
            { fruit: 'Melon', count: 4500 }
        ]} weightValuePath='count' leafItemSettings={{
            labelPath: 'fruit'
        }} tooltipSettings={{
            visible: true
        }}>
        <Inject services={[TreeMapTooltip]}/>
    </TreeMapComponent>);
    }
}

Format tooltip

By default, tooltip shows information about weight value of current item. In addition, to show more information in tooltip, format the tooltip as ${datafield} from data source.

The following example shows formatting the tooltip.

            { fruit:'Mango', count:3000 },
            { fruit:'Orange', count:2300 },
            { fruit:'Banana', count:500 },
            { fruit:'Grape', count:4300 },
            { fruit:'Papaya', count:1200 },
            { fruit:'Melon', count:4500 }
        ]}
        weightValuePath= 'count'
        leafItemSettings= {{
            labelPath: 'fruit'
        }}
        tooltipSettings= {{
            visible: true,
            format:'Name:${fruit} - TotalCount:${count}'
        }}>
        <Inject services={[TreeMapTooltip]} />
    </TreeMapComponent> );
 }
}
import * as React from "react";

export class App extends React.Component {
    render() {
        return (<TreeMapComponent id='treemap' dataSource={[
            { fruit: 'Apple', count: 5000 },
            { fruit: 'Mango', count: 3000 },
            { fruit: 'Orange', count: 2300 },
            { fruit: 'Banana', count: 500 },
            { fruit: 'Grape', count: 4300 },
            { fruit: 'Papaya', count: 1200 },
            { fruit: 'Melon', count: 4500 }
        ]} weightValuePath='count' leafItemSettings={{
            labelPath: 'fruit'
        }} tooltipSettings={{
            visible: true,
            format: 'Name:${fruit} - TotalCount:${count}'
        }}>
        <Inject services={[TreeMapTooltip]}/>
    </TreeMapComponent>);
    }
}

Tooltip template

Any HTML element can be displayed in tooltip using the ‘template’ property. You can use ${datafield} as placeholder in HTML element to display the values from data source.

The following example shows tootip template.
