Getting started with EJ2 TypeScript 3D Circular Chart control

19 Feb 20267 minutes to read

This document explains how to create a simple 3D Circular Chart and configure its features in TypeScript using the Essential JS 2 webpack quickstart seed repository.

This application is integrated with the webpack.config.js configuration and uses the latest version of the webpack-cli. It requires node v14.15.0 or higher. For more information about webpack and its features, refer to the webpack getting-started guide.

Dependencies

Below is the list of minimum dependencies required to use the 3D Circular Chart.

|-- @syncfusion/ej2-charts
    |-- @syncfusion/ej2-base
    |-- @syncfusion/ej2-data
    |-- @syncfusion/ej2-pdf-export
    |-- @syncfusion/ej2-file-utils
    |-- @syncfusion/ej2-compression
    |-- @syncfusion/ej2-svg-base

Set up development environment

Open the command prompt from the required directory, and run the following command to clone the Syncfusion JavaScript (Essential JS 2) quickstart project from GitHub.

git clone https://github.com/SyncfusionExamples/ej2-quickstart-webpack ej2-quickstart

After cloning the application in the ej2-quickstart folder, run the following command line to navigate to the ej2-quickstart folder.

cd ej2-quickstart

Add Syncfusion JavaScript packages

Syncfusion JavaScript (Essential JS 2) packages are available on the npmjs.com public registry. You can install all Syncfusion JavaScript (Essential JS 2) controls in a single @syncfusion/ej2 package or individual packages for each control.

The quickstart application is preconfigured with the dependent @syncfusion/ej2 package in the ~/package.json file. Use the following command to install the dependent npm packages from the command prompt.

npm install

Add 3D Circular Chart to the project

Open the project in Visual Studio Code and add the 3D Circular Chart to the application.

Add the HTML div tag with its id attribute as element in your ~/src/index.html file to initialize the 3D Circular Chart.

<body>
     <!--container which is going to render the 3D Circular Chart-->
     <div id='element'>
     </div>
</body>

</html>

Import a 3D Circular Chart component in src/app/app.ts to instantiate and render the 3D Circular Chart.

import { CircularChart3D } from '@syncfusion/ej2-charts';

// initialize 3D Circular Chart component
let circularchart: CircularChart3D = new CircularChart3D();

// render initialized 3D Circular Chart
circularchart.appendTo('#element');

Pie Series

By default, the pie series will be rendered when assigning the JSON data to the series using the dataSource property. Map the field names in the JSON data to the xName and yName properties of the series.

import { CircularChart3D, PieSeries3D, CircularChartDataLabel3D, CircularChartLegend3D } from '@syncfusion/ej2-charts';
CircularChart3D.Inject(PieSeries3D, CircularChartDataLabel3D, CircularChartLegend3D);
let circularchart: CircularChart3D = new CircularChart3D({
    series: [
        {
            dataSource: [
                { x: 'Chrome', y: 62.92 },
                { x: 'Internet Explorer', y: 6.12 },

                name: 'x',
                position: 'Outside',
                font: {
                    fontWeight: '600'
                },
                connectorStyle: { length: '40px' }
