import { AreaSeriesService, DateTimeService, RangeTooltipService} from '@syncfusion/ej2-angular-charts'

@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>

})
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';
