23 Sep 20235 minutes to read

This section explains how to customize the sparkline with multiple range bands.

Range band customization

The range band feature is used to highlight a particular range along with the y-axis using the [startRange] and [endRange] properties. You can also customize the [color] and [opacity] of the range band.

[app.component.ts]

app.component.ts

import { Component } from '@angular/core';

@Component({
    selector: 'app-container',
    template: `<ejs-sparkline id='container' width='150px' height='150px' lineWidth= 2 fill = '#0d3c9b' [rangeBandSettings] = 'rangeBandSettings' [dataSource]="data">
    </ejs-sparkline>`
})
export class AppComponent {
    public data: object[] = [ 0, 6, 4, 1, 3, 2, 5 ] as any;
    public rangeBandSettings: object[] = [{
        startRange: 1,
        endRange: 3,
        color: '#bfd4fc',
        opacity:0.4
        }];
};

app.module.ts

import { NgModule } from '@angular/core';
import { BrowserModule } from '@angular/platform-browser';
import { AppComponent } from './app.component';
import { SparklineModule, SparklineTooltipService } from '@syncfusion/ej2-angular-charts';

/**
 * Module
 */
@NgModule({
    imports: [
        BrowserModule, SparklineModule
    ],
    declarations: [AppComponent],
    bootstrap: [AppComponent],
	providers: [SparklineTooltipService]
})
export class AppModule { }

main.ts

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

import 'zone.js';
enableProdMode();
platformBrowserDynamic().bootstrapModule(AppModule);

Multiple range band customization

You can define multiple range bands to a sparkline as shown in the following code sample.

[app.component.ts]

app.component.ts

import { Component } from '@angular/core';

@Component({
    selector: 'app-container',
    template: `<ejs-sparkline id='container' width='150px' height='150px' lineWidth= 2 fill= '#0d3c9b' [rangeBandSettings] ='rangeBandSettings' [dataSource]="data" >
    </ejs-sparkline>`
})
export class AppComponent {
    public data: object[] = [0, 6, 4, 1, 3, 2, 5] as any;
    public rangeBandSettings: object[] = [
            {
                startRange: 1,
                endRange: 2,
                color: '#bfd4fc',
                opacity:0.4
            },
            {
                startRange: 4,
                endRange: 5,
                color: 'red',
                opacity:0.4
            }
        ]
};

app.module.ts

import { NgModule } from '@angular/core';
import { BrowserModule } from '@angular/platform-browser';
import { AppComponent } from './app.component';
import { SparklineModule, SparklineTooltipService } from '@syncfusion/ej2-angular-charts';

/**
 * Module
 */
@NgModule({
    imports: [
        BrowserModule, SparklineModule
    ],
    declarations: [AppComponent],
    bootstrap: [AppComponent],
	providers: [SparklineTooltipService]
})
export class AppModule { }

main.ts

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

import 'zone.js';
enableProdMode();
platformBrowserDynamic().bootstrapModule(AppModule);
