Comparative bar in Angular Bullet chart component

20 Sep 20226 minutes to read

The line marker that runs perpendicular to the orientation of the graph is known as the Comparative Measure and it is used as a target marker to compare against the feature measure value. This is also called as the Target Bar in the Bullet Chart. To display the target bar, the targetField should be mapped to the appropriate field from the datasource.

import { Component } from '@angular/core';
import { AnimationModel } from '@syncfusion/ej2-charts';

@Component({
    selector: 'app-container',
    template: `<ejs-bulletchart targetField='target' [minimum]='minimum' [maximum]='maximum'
  [interval]='interval' [dataSource]='data' [animation]='animation' [tooltip]='tooltip'>
  <e-bullet-range-collection>
    <e-bullet-range end='35' color='#ebebeb'></e-bullet-range>
    <e-bullet-range end='70' color='#d8d8d8'></e-bullet-range>
    <e-bullet-range end='100' color='#7f7f7f'></e-bullet-range>
  </e-bullet-range-collection>
</ejs-bulletchart>`
})
export class AppComponent {
  public minimum: number = 0;
  public maximum: number = 100;
  public interval: number = 20;
  public data: Object[] = [
      { value: 55, target: 75 }
    ];
  public animation: AnimationModel = { enable: false };
  public tooltip: Object = { enable: false };
}
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();

Types of Target Bar

The shape of the target bar can be customized using the targetTypes property and it supports Circle, Cross, and Rect shapes. The default type of the target bar is Rect.

import { Component } from '@angular/core';
import { AnimationModel } from '@syncfusion/ej2-charts';

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

  public animation: AnimationModel = { enable: false };
  public tooltip: Object = { enable: false };
}

Target Bar Customization

The following properties can be used to customize the Target Bar.

import { Component } from '@angular/core';
import { AnimationModel } from '@syncfusion/ej2-charts';

@Component({
    selector: 'app-container',
    template: `<ejs-bulletchart targetField='target' [minimum]='minimum' [maximum]='maximum'
  [interval]='interval' [dataSource]='data' [animation]='animation' targetColor='red' targetWidth=15  [tooltip]='tooltip'>
  <e-bullet-range-collection>
