Getting started with Angular Accumulation Chart component

18 Feb 20268 minutes to read

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

Note: This guide supports Angular 21 and other recent Angular versions. For detailed compatibility with other Angular versions, please refer to the Angular version support matrix. Starting from Angular 19, standalone components are the default, and this guide reflects that architecture.

Prerequisites

Ensure your development environment meets the System Requirements for Syncfusion^® Angular UI Components.

Setup Angular environment

A straightforward approach to begin with Angular is to create a new application using the Angular CLI. Install Angular CLI globally with the following command:

npm install -g @angular/cli

Angular 21 Standalone Architecture: Standalone components are the default in Angular 21. This guide uses the modern standalone architecture. If you need more information about the standalone architecture, refer to the Standalone Guide.

Installing a specific version

To install a particular version of Angular CLI, use:

npm install -g @angular/[email protected]

Create an Angular application

With Angular CLI installed, execute this command to generate a new application:

ng new syncfusion-angular-app

• This command will prompt you to configure settings like enabling Angular routing and choosing a stylesheet format.

? Which stylesheet format would you like to use? (Use arrow keys)
> CSS             [ https://developer.mozilla.org/docs/Web/CSS                     ]
  Sass (SCSS)     [ https://sass-lang.com/documentation/syntax#scss                ]
  Sass (Indented) [ https://sass-lang.com/documentation/syntax#the-indented-syntax ]
  Less            [ http://lesscss.org                                             ]

• By default, a CSS-based application is created. Use SCSS if required:

ng new syncfusion-angular-app --style=scss

• During project setup, when prompted for the Server-side rendering (SSR) option, choose the appropriate configuration.

• Select the required AI tool or ‘none’ if you do not need any AI tool.

• Navigate to your newly created application directory:

cd syncfusion-angular-app

Note: In Angular 19 and below, the CLI generates files like app.component.ts, app.component.html, app.component.css, etc. In Angular 20+, the CLI generates a simpler structure with src/app/app.ts, app.html, and app.css (no .component. suffixes).

Installing Syncfusion^® AccumulationChart package

Syncfusion^®’s Angular component packages are available on npmjs.com. To use Syncfusion^® Angular components, install the necessary package.

This guide uses the Angular Accumulation Chart component for demonstration. Add the Angular Accumulation Chart component with:

ng add @syncfusion/ej2-angular-charts

The above command will perform the following configurations:

• Add the @syncfusion/ej2-angular-charts package and peer dependencies to your package.json.
• Import the Accumulation Chart component in your application.

For more details on version compatibility, refer to the Version Compatibility section.

Syncfusion^® offers two package structures for Angular components:

1. Ivy library distribution package format
2. Angular compatibility compiler (ngcc), which is Angular’s legacy compilation pipeline.

Ivy library distribution package

Syncfusion^®’s latest Angular packages are provided as Ivy-compatible and suited for Angular 12 and above. To install the package, execute:

ng add @syncfusion/ej2-angular-charts

Angular compatibility compiled package(ngcc)

For applications not compiled with Ivy, use the ngcc tagged packages:

The ngcc packages are still compatible with Angular CLI versions 15 and below. However, they may generate warnings suggesting the use of Ivy compiled packages. Starting from Angular 16, support for the ngcc package has been completely removed. If you have further questions regarding ngcc compatibility, please refer to the following FAQ.

npm add @syncfusion/[email protected]

Add accumulationChart component

Modify the template in app.component.ts file to render the Accumulation Charts component [src/app/app.component.ts].

import { AccumulationChartAllModule } from '@syncfusion/ej2-angular-charts';
import { Component, ViewEncapsulation } from '@angular/core';

@Component({
    imports: [AccumulationChartAllModule],
    standalone: true,
    selector: 'app-container',
    // specifies the template string for the Accumulation Charts component
    template: `<ejs-accumulationchart id="pie-container"></ejs-accumulationchart>`,
    encapsulation: ViewEncapsulation.None
})
export class AppComponent { }

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

<app-container></app-container>

Use the ng serve command to run the application in the browser.

ng serve

Pie series

By default, a pie series is rendered when JSON data is assigned to the series dataSource property. Map JSON fields to the series xName and yName properties to bind data correctly.

app.component.ts

import { AccumulationChartModule } from '@syncfusion/ej2-angular-charts';
import { PieSeriesService, AccumulationLegendService } from '@syncfusion/ej2-angular-charts';
import { Component, OnInit } from '@angular/core';

@Component({
    imports: [AccumulationChartModule],
    providers: [PieSeriesService, AccumulationLegendService],
    standalone: true,
    selector: 'app-container',
    template: `<ejs-accumulationchart id="chart-container" [legendSettings]='legendSettings'>
        <e-accumulation-series-collection>
            <e-accumulation-series [dataSource]='piedata' xName='x' yName='y'></e-accumulation-series>
        </e-accumulation-series-collection>
    </ejs-accumulationchart>`
})
export class AppComponent implements OnInit {
    public piedata?: Object[];
    public legendSettings?: Object;
    ngOnInit(): void {
        this.piedata = [
            { x: 'Jan', y: 3, text: 'Jan: 3' }, { x: 'Feb', y: 3.5, text: 'Feb: 3.5' },
            { x: 'Mar', y: 7, text: 'Mar: 7' }, { x: 'Apr', y: 13.5, text: 'Apr: 13.5' },
            { x: 'May', y: 19, text: 'May: 19' }, { x: 'Jun', y: 23.5, text: 'Jun: 23.5' },
            { x: 'Jul', y: 26, text: 'Jul: 26' }, { x: 'Aug', y: 25, text: 'Aug: 25' },
            { x: 'Sep', y: 21, text: 'Sep: 21' }, { x: 'Oct', y: 15, text: 'Oct: 15' },
            { x: 'Nov', y: 9, text: 'Nov: 9' }, { x: 'Dec', y: 3.5, text: 'Dec: 3.5' }];
        this.legendSettings = {
            visible: false
        };
    }
}

main.ts

import { bootstrapApplication } from '@angular/platform-browser';
import { AppComponent } from './app/app.component';
import 'zone.js';
bootstrapApplication(AppComponent).catch((err) => console.error(err));
