Customization in Angular Range navigator component

20 Sep 202217 minutes to read

Navigator appearance

The Range Selector can be customized by using the navigatorStyleSettings. The selectedRegionColor property is used to specify the color for the selected region, whereas the unselectedRegionColor property is used to specify the color for the unselected region.

app.component.ts
app.module.ts
main.ts
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' [navigatorStyleSettings]='navigatorStyle' labelFormat='MMM-yy'>
            <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 navigatorStyle: Object;
    ngOnInit(): void {
        this.value = [new Date('2017-09-01'), new Date('2018-02-01')];
        this.chartData = datasrc;
        this.navigatorStyle = {  unselectedRegionColor: 'skyblue', selectedRegionColor: 'pink' };
    }
}
import { NgModule } from '@angular/core';
import { BrowserModule } from '@angular/platform-browser';
import { AppComponent } from './app.component';
import { ChartModule, RangeNavigatorModule } from '@syncfusion/ej2-angular-charts';
import { AreaSeriesService, DateTimeService} from '@syncfusion/ej2-angular-charts';

/**
 * Module
 */
@NgModule({
    imports: [
        BrowserModule, ChartModule, RangeNavigatorModule
    ],
    declarations: [AppComponent],
    bootstrap: [AppComponent],
    providers: [ AreaSeriesService, DateTimeService ]
})
export class AppModule { }
import { platformBrowserDynamic } from '@angular/platform-browser-dynamic';
import { enableProdMode } from '@angular/core';
import { AppModule } from './app.module';

enableProdMode();
platformBrowserDynamic().bootstrapModule(AppModule);

Thumb

The thumb property allows to customize the border, fill color, size, and type of thumb. Thumbs can be of two shapes: Circle and Rectangle.

app.component.ts
app.module.ts
main.ts
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' [navigatorStyleSettings]='navigatorStyle' labelFormat='MMM-yy'>
            <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 navigatorStyle: Object;
    ngOnInit(): void {
        this.value = [new Date('2017-09-01'), new Date('2018-02-01')];
        this.chartData = datasrc;
        this.navigatorStyle = { thumb:{ type: 'Rectangle', border: { width: 2, color: 'red'}, fill: 'pink' }};

    }
}
import { NgModule } from '@angular/core';
import { BrowserModule } from '@angular/platform-browser';
import { AppComponent } from './app.component';
import { ChartModule, RangeNavigatorModule } from '@syncfusion/ej2-angular-charts';
import { AreaSeriesService, DateTimeService} from '@syncfusion/ej2-angular-charts';

/**

@NgModule({
    imports: [
        BrowserModule, ChartModule, RangeNavigatorModule
    ],
    declarations: [AppComponent],
    bootstrap: [AppComponent],
    providers: [ AreaSeriesService, DateTimeService ]
})
export class AppModule { }
import { platformBrowserDynamic } from '@angular/platform-browser-dynamic';
import { enableProdMode } from '@angular/core';
import { AppModule } from './app.module';

enableProdMode();
platformBrowserDynamic().bootstrapModule(AppModule);

Border customization

Using the navigatorBorder, the width and color of the Range Selector border can be customized.

app.component.ts
app.module.ts
main.ts
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' [navigatorBorder]='navigatorBorder' labelFormat='MMM-yy'>
            <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 navigatorBorder: Object;
    ngOnInit(): void {
        this.value = [new Date('2017-09-01'), new Date('2018-02-01')];
        this.chartData = datasrc;
        this.navigatorBorder = {  width: 4, color: 'green'};

    }
}
import { NgModule } from '@angular/core';
import { BrowserModule } from '@angular/platform-browser';
import { AppComponent } from './app.component';
import { ChartModule, RangeNavigatorModule } from '@syncfusion/ej2-angular-charts';
import { AreaSeriesService, DateTimeService} from '@syncfusion/ej2-angular-charts';

/**

@NgModule({
    imports: [
        BrowserModule, ChartModule, RangeNavigatorModule
    ],
    declarations: [AppComponent],
    bootstrap: [AppComponent],
    providers: [ AreaSeriesService, DateTimeService ]
})
export class AppModule { }
import { platformBrowserDynamic } from '@angular/platform-browser-dynamic';
import { enableProdMode } from '@angular/core';
import { AppModule } from './app.module';

enableProdMode();
platformBrowserDynamic().bootstrapModule(AppModule);

Deferred update

If the enableDeferredUpdate property is set to true, then the changed event will be triggered after dragging the slider. If the enableDeferredUpdate is false, then the changed event will be triggered when dragging the slider. By default, the enableDeferredUpdate is set to false.

app.component.ts
app.module.ts
main.ts
import { Component, OnInit, ViewChild } from '@angular/core';
import { datasrc } from 'datasource.ts';
import { IChangedEventArgs }  from "@syncfusion/ej2-charts";

     @ViewChild('chart')
    public chart: Chart;
    public periodsValue: Object[];
    public chartData: Object[];
    public value: Object[];
    public tooltip: Object;
    public enableDeferredUpdate: booloean;
    public changed: IChangedEventArgs;
    public primaryXAxis: object;
    public legendSettings: object;
    ngOnInit(): void {
        this.primaryXAxis = {
            valueType: 'DateTime',
            edgeLabelPlacement: 'Shift'
        };
        this.legendSettings= { visible: false };
        this.chartData = datasrc;
        this.value=[new Date('2017-09-01'), new Date('2018-02-01')];

            this.chart.primaryXAxis.zoomPosition = args.zoomPosition;
            this.chart.dataBind();

        }
    }

Allow snapping

The allowSnapping property toggles the placement of the slider exactly to the left or on the nearest interval.

app.component.ts
app.module.ts
main.ts
import { Component, OnInit } from '@angular/core';
import { datasrc } from 'datasource.ts'

@Component({
    selector: 'app-container',

import { platformBrowserDynamic } from '@angular/platform-browser-dynamic';
import { enableProdMode } from '@angular/core';
import { AppModule } from './app.module';

enableProdMode();
platformBrowserDynamic().bootstrapModule(AppModule);

Animation

The speed of the animation can be controlled using the animationDuration property. The default value of the animationDuration property is 500 milliseconds.

app.component.ts
app.module.ts
main.ts
import { Component, OnInit } from '@angular/core';
