21 Jul 20267 minutes to read

The tooltip for sliders are supported by the Range Selector. Sliders are used in the Range Selector to select data from a specific range. The tooltip displays the selected start and end values.

Enable tooltip

The tooltip is useful to show the selected data. You can enable the tooltip by setting the enable property as true in the tooltip object and by injecting the RangeTooltipService module into the providers array.

import { Component, OnInit } from '@angular/core';
import { ChartModule, RangeNavigatorModule, AreaSeriesService, DateTimeService, RangeTooltipService } from '@syncfusion/ej2-angular-charts';
import { datasrc } from './data';

@Component({
    imports: [ChartModule, RangeNavigatorModule],
    providers: [AreaSeriesService, DateTimeService, RangeTooltipService],
    standalone: true,
    selector: 'app-root',
    template: `<ejs-rangenavigator id="rn-container" valueType='DateTime' [value]='value' [tooltip]='tooltip'>
        <e-rangenavigator-series-collection>
            <e-rangenavigator-series [dataSource]='chartData' type='Area' xName='x' yName='y' width=2>
            </e-rangenavigator-series>
        </e-rangenavigator-series-collection>
    </ejs-rangenavigator>`
})
export class AppComponent implements OnInit {
    public value?: Object[];
    public chartData?: Object[];
    public tooltip?: Object;

    ngOnInit(): void {
        this.value = [new Date('2017-09-01'), new Date('2018-02-01')];
        this.chartData = datasrc;
        this.tooltip = { enable: true, displayMode: 'Always' };
    }
}
import { bootstrapApplication } from '@angular/platform-browser';
import { AppComponent } from './app.component';
import 'zone.js';
bootstrapApplication(AppComponent).catch((err) => console.error(err));

Label Format

The labelFormat property in the tooltip is used to format and parse the date to all globalize formats.

import { NgModule } from '@angular/core'
import { BrowserModule } from '@angular/platform-browser'
import { ChartModule, RangeNavigatorModule } from '@syncfusion/ej2-angular-charts'
import { AreaSeriesService, DateTimeService, RangeTooltipService} from '@syncfusion/ej2-angular-charts'




import { Component, OnInit } from '@angular/core';
import { datasrc } from './data';

@Component({
imports: [
         ChartModule, RangeNavigatorModule
    ],

providers: [ AreaSeriesService, DateTimeService, RangeTooltipService ],
standalone: true,
    selector: 'app-container',
    template: `<ejs-rangenavigator id="rn-container" valueType='DateTime' [value]='value' [tooltip]='tooltip'>
            <e-rangenavigator-series-collection>
                <e-rangenavigator-series [dataSource]='chartData' type='Area' xName='x' yName='y' width=2>
                </e-rangenavigator-series>
            </e-rangenavigator-series-collection>
        </ejs-rangenavigator>`
})
export class AppComponent implements OnInit {
    public value?: Object[];
    public chartData?: Object[];
    public tooltip?: Object;
    ngOnInit(): void {
        this.value = [new Date('2017-09-01'), new Date('2018-02-01')];
        this.chartData = datasrc;
        this.tooltip = { enable: true, displayMode: 'Always', labelFormat: 'y/M/d' };
    }
}
import { bootstrapApplication } from '@angular/platform-browser';
import { AppComponent } from './app.component';
import 'zone.js';
bootstrapApplication(AppComponent).catch((err) => console.error(err));
