Getting started with Angular Bullet Chart component

26 Sep 2022 / 6 minutes to read

This section explains you the steps required to create a simple Bullet Chart and demonstrate the basic usage of the Bullet Chart component in an Angular environment.

Setup Angular Environment

You can use Angular CLI to setup your Angular applications. To install Angular CLI use the following command.

npm install -g @angular/cli

Create an Angular Application

Start a new Angular application using below Angular CLI command.

ng new my-app
cd my-app

Installing Syncfusion BulletChart package

Syncfusion packages are distributed in npm as @syncfusion scoped packages. You can get all the Angular Syncfusion package from npm link.

Currently, Syncfusion provides two types of package structures for Angular components,

Ivy library distribution package format
Angular compatibility compiler(Angular’s legacy compilation and rendering pipeline) package.

Ivy library distribution package

Syncfusion Angular packages(>=20.2.36) has been moved to the Ivy distribution to support the Angular Ivy rendering engine and the package are compatible with Angular version 12 and above. To download the package use the below command.

Add @syncfusion/ej2-angular-charts package to the application.

npm install @syncfusion/ej2-angular-charts --save

Angular compatibility compiled package(ngcc)

For Angular version below 12, you can use the legacy (ngcc) package of the Syncfusion Angular components. To download the ngcc package use the below.

Add @syncfusion/ej2-angular-charts@ngcc package to the application.

npm install @syncfusion/ej2-angular-charts@ngcc --save

To mention the ngcc package in the package.json file, add the suffix -ngcc with the package version as below.

@syncfusion/ej2-angular-charts:"20.2.38-ngcc"

Note: If the ngcc tag is not specified while installing the package, the Ivy Library Package will be installed and this package will throw a warning.

Registering Bullet Chart Module

Import Bullet Chart module into Angular application(app.module.ts) from the package @syncfusion/ej2-angular-charts [src/app/app.module.ts].

import { NgModule } from '@angular/core';
import { BrowserModule } from '@angular/platform-browser';
// import the BulletChartModule for the Chart component
import { BulletChartModule } from '@syncfusion/ej2-angular-charts';
import { AppComponent }  from './app.component';

@NgModule({
  //declaration of ChartModule into NgModule
  imports:      [ BrowserModule, BulletChartModule ],
  declarations: [ AppComponent ],
  bootstrap:    [ AppComponent ]
})
export class AppModule { }

Modify the template in app.component.ts file to render the ej2-angular-charts component [src/app/app.component.ts].

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

@Component({
  selector: 'app-container',
  // specifies the template string for the Bullet Charts component
  template: `<ejs-bulletchart id='container'></ejs-bulletchart>`,
  encapsulation: ViewEncapsulation.None
})
export class AppComponent  { }

Now use the app-container in the index.html instead of default one.

<app-container></app-container>

Now run the application in the browser using the below command.

npm start

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

@Component({
selector: 'app-container',
// specifies the template string for the Chart component
template: `<ejs-chart id="chart-container"></ejs-chart>`
})
export class AppComponent {

}

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

/**

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

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

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

Module Injection

Bullet Chart component are segregated into individual feature-wise modules. In order to use a particular feature, you need to inject its feature service in the AppModule. Please find relevant feature service name and description as follows.

BulletTooltipService - Inject this provider to use tooltip feature.

These modules should be injected to the provider section as follows,

import { NgModule } from '@angular/core';
import { BrowserModule } from '@angular/platform-browser';
import { AppComponent } from './app.component';
import { BulletChartComponent } from '@syncfusion/ej2-angular-charts';
import { BulletTooltipService } from '@syncfusion/ej2-angular-charts';
@NgModule({
    imports: [
        BrowserModule,
    ],
    declarations: [AppComponent, BulletChartComponent],
    bootstrap: [AppComponent],
    providers: [ BulletTooltipService ]
})

Bullet Chart with Data

This section explains how to plot local data to the bullet chart.

export class AppComponent implements OnInit {
public data: Object[];
ngOnInit(): void {
    // Data for bullet chart
    this.data = [
   { value: 100, target: 80 },
   { value: 200, target: 180 },
   { value: 300, target: 280 },
   { value: 400, target: 380 },
   { value: 500, target: 480 },
    ];
}
}

Now assign the local data to dataSource property. value and target values should be mapped with valueField and targetField respectively.

@Component({

template: `<ejs-bulletchart valueName='value' targetName='target'

            </ejs-bulletchart>`
})
export class AppComponent {
  public minimum: number = 0;
  public maximum: number = 300;
  public interval: number = 50;
  public data: Object[] = [
   { value: 100, target: 80 },
   { value: 200, target: 180 },
   { value: 300, target: 280 },
   { value: 400, target: 380 },
   { value: 500, target: 480 },
];
}

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

/**

@NgModule({
    imports: [
        BrowserModule, BulletChartModule
    ],
    declarations: [AppComponent],
    bootstrap: [AppComponent],
    providers: [ ]
})
export class AppModule { }

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

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

Add Bullet Chart Title

You can add a title using title property to the bullet chart to provide quick information to the user about the data plotted in the bullet chart.

export class AppComponent {
  public minimum: number = 0;
  public maximum: number = 300;

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

Ranges

You can add a range using ranges property to the bullet chart.

export class AppComponent {
  public minimum: number = 0;
  public maximum: number = 300;
  public interval: number = 50;
  public data: Object[] = [
  { value: 270, target: 250 }
];
}

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

/**

@NgModule({
    imports: [
        BrowserModule, BulletChartModule
    ],
    declarations: [AppComponent],
    bootstrap: [AppComponent],
    providers: [ ]
})
export class AppModule { }

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

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

The tooltip is useful when you cannot display information by using the data labels due to space constraints. You can enable tooltip by setting the enable property as true in tooltip object and by injecting BulletTooltipService into the @NgModule.providers.
