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.
You can use Angular CLI
to setup your Angular applications. To install Angular CLI use the following command.
npm install -g @angular/cli
Start a new Angular application using below Angular CLI command.
ng new my-app
cd my-app
All the available Essential JS 2 packages are published in npmjs.com
registry.
To install Bullet Chart component, use the following command.
npm install @syncfusion/ej2-angular-charts --save
The —save will instruct NPM to include the bullet chart package inside of the dependencies
section of the package.json
.
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 { }
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';
/**
* Module
*/
@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);
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 ]
})
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.
import { Component } from '@angular/core';
@Component({
selector: 'app-container',
template: `<ejs-bulletchart valueName='value' targetName='target'
[minimum]='minimum' [maximum]='maximum' [interval]='interval' [dataSource]='data'>
</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';
/**
* Module
*/
@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);
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.
import { Component } from '@angular/core';
@Component({
selector: 'app-container',
template: `<ejs-bulletchart valueName='value' targetName='target' title='Revenue'
[minimum]='minimum' [maximum]='maximum' [interval]='interval' [dataSource]='data'>
</ejs-bulletchart>`
})
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';
/**
* Module
*/
@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);
You can add a range using ranges
property to the bullet chart.
import { Component } from '@angular/core';
@Component({
selector: 'app-container',
template: `<ejs-bulletchart valueName='value' targetName='target' title='Revenue'
[minimum]='minimum' [maximum]='maximum' [interval]='interval' [dataSource]='data'>
<e-bullet-range-collection>
<e-bullet-range end='100' color='#ebebeb'></e-bullet-range>
<e-bullet-range end='200' color='#d8d8d8'></e-bullet-range>
<e-bullet-range end='300' color='#7f7f7f'></e-bullet-range>
</e-bullet-range-collection>
</ejs-bulletchart>`
})
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';
/**
* Module
*/
@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
.
import { Component } from '@angular/core';
@Component({
selector: 'app-container',
template: `<ejs-bulletchart valueName='value' targetName='target' title='Revenue'
[minimum]='minimum' [maximum]='maximum' [interval]='interval' [dataSource]='data'
[tooltip]='tooltip'>
<e-bullet-range-collection>
<e-bullet-range end='100' color='#ebebeb'></e-bullet-range>
<e-bullet-range end='200' color='#d8d8d8'></e-bullet-range>
<e-bullet-range end='300' color='#7f7f7f'></e-bullet-range>
</e-bullet-range-collection>
</ejs-bulletchart>`
})
export class AppComponent {
public minimum: number = 0;
public maximum: number = 300;
public interval: number = 50;
public tooltip: Object = {enable: true};
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';
import { BulletTooltipService} from '@syncfusion/ej2-angular-charts';
/**
* Module
*/
@NgModule({
imports: [
BrowserModule, BulletChartModule
],
declarations: [AppComponent],
bootstrap: [AppComponent],
providers: [ BulletTooltipService ]
})
export class AppModule { }
import { platformBrowserDynamic } from '@angular/platform-browser-dynamic';
import { enableProdMode } from '@angular/core';
import { AppModule } from './app.module';
enableProdMode();
platformBrowserDynamic().bootstrapModule(AppModule);
