Getting Started with Angular 3D Circular Chart Component

This section explains the steps required to create a simple Angular 3D Circular Chart and demonstrates the basic usage of the Angular 3D Circular Chart component.

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

Before getting started, ensure that your environment meets the system requirements for Syncfusion® Angular UI components, which covers supported Node.js, Angular, and @syncfusion/ej2-angular-charts versions.

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

Verify the installation:

ng version

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

Initial setup

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

Initial setup

  • 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® 3D Circular Chart 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 3D Circular Chart component for demonstration. Add the Angular Chart package 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 3D Circular Chart component in your application.

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

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:

Note: 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 install @syncfusion/[email protected]

Add the 3D Circular Chart Component

Modify the template in src/app/app.component.ts (or src/app/app.ts in Angular 20+) to render the 3D Circular Chart component:

import { Component, ViewEncapsulation } from '@angular/core';
import { CircularChart3DAllModule } from '@syncfusion/ej2-angular-charts';

@Component({
    imports: [CircularChart3DAllModule],
    standalone: true,
    selector: 'app-root',
    // specifies the template string for the 3D Circular Chart component
    template: `<ejs-circularchart3d id='chart-container'></ejs-circularchart3d>`,
    encapsulation: ViewEncapsulation.None
})
export class AppComponent { }

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

ng serve

Verify that an empty 3D Circular Chart renders before proceeding to the next step.

Note: CircularChart3DAllModule registers every available service at once, which is convenient for getting started. For production, prefer the granular CircularChart3DModule and inject only the services you need.

Pie Series

By default, the pie series is rendered when you assign JSON data to the series via the dataSource property. Map the field names in the JSON data to the xName and yName properties of the series.

The 3D Circular Chart renders a 3D pie with one slice for each data point. Hovering over a slice displays a tooltip with the corresponding value.

import { CircularChart3DAllModule } from '@syncfusion/ej2-angular-charts';
import { Component, OnInit } from '@angular/core';

@Component({
    imports: [CircularChart3DAllModule],
    standalone: true,
    selector: 'app-container',
    template: `<ejs-circularchart3d style='display:block;' align='center' tilt='-45' [title]='title' [legendSettings]="legendSettings">
    <e-circularchart3d-series-collection>
    <e-circularchart3d-series [dataSource]='dataSource' xName='x' yName='y' [dataLabel]='dataLabel'>
    </e-circularchart3d-series></e-circularchart3d-series-collection>
    </ejs-circularchart3d>`
})
export class AppComponent implements OnInit {
    public dataSource?: Object[];
    public title?: string;
    public legendSettings?: Object;
    public dataLabel?: Object;
    ngOnInit(): void {
        this.dataSource = [
            { x: 'Chrome', y: 62.92 },
            { x: 'Internet Explorer', y: 6.12 },
            { x: 'Opera', y: 3.15 },
            { x: 'Edge', y: 5.5 },
            { x: 'Safari', y: 19.97 },
            { x: 'Others', y: 2.34 }];
        this.title = 'Browser Market Shares in November 2023';
        this.legendSettings = { visible: true, position: 'Right' };
        this.dataLabel = {
            visible: true,
            name: 'x',
            position: 'Outside',
            font: {
                fontWeight: '600'
            },
            connectorStyle: { length: '40px' }
        };
    }
}
import { bootstrapApplication } from '@angular/platform-browser';
import { AppComponent } from './app.component';
import 'zone.js';
bootstrapApplication(AppComponent).catch((err) => console.error(err));

Troubleshooting

If the 3D Circular Chart does not render as expected, check for these common issues:

  • Chart not visible: Verify that ViewEncapsulation.None is set on the component, that the id on <ejs-circularchart3d> is unique, and that the selector matches the root element in index.html (commonly <app-root>).
  • 3D scene looks flat: Check that <e-circularchart3d-series> is wrapped in <e-circularchart3d-series-collection> and that the 3D rotation/perspective settings are configured.
  • Data not displayed: Verify that the xName and yName values match the field names in the data source exactly.
  • Build errors: Run ng version to confirm that Node.js, Angular CLI, and @syncfusion/ej2-angular-charts are on supported versions.
  • Port already in use: If ng serve fails because port 4200 is in use, run ng serve --port 4201 (or another free port) instead.
