The left and right thumb of RangeNavigator are used to indicate the selected range in the large collection of data. Following are the ways you can select a range.
Following code example shows how to configure the selected range using value property of RangeNavigator.
import { Component, OnInit } from '@angular/core';
import { datasrc } from 'datasource.ts'
@Component({
selector: 'app-container',
template:
`<ejs-rangenavigator id="rn-container" valueType='DateTime' [value]='value' [tooltip]='tooltip'
[labelFormat]='labelFormat'>
<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[];
public labelFormat: string;
ngOnInit(): void {
this.value = [new Date('2017-09-01'), new Date('2018-02-01')];
this.chartData = datasrc;
this.tooltip = { enable: true, displayMode: 'Always' };
this.labelFormat = 'MMM-yy';
}
}
