Getting started in EJ2 TypeScript Accumulation chart control

7 May 20256 minutes to read

This article provides a step-by-step guide to configuring the Syncfusion® JavaScript (Essential® JS 2) library and building a simple JavaScript web application using the GitHub 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 documentation.

Dependencies

The list of minimum dependencies required to use an accumulation chart are follows:

|-- @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 Accumulation Chart to the Project

Open the application in Visual Studio Code and add the Syncfusion® JavaScript UI controls.

Add the HTML div tag with its id attribute as element in your ~/src/index.html file to initialize the Accumulation chart.

<!DOCTYPE html>
<html lang="en">

<head>
    <title>EJ2 Animation</title>
    <meta charset="utf-8" />
    <meta name="viewport" content="width=device-width, initial-scale=1.0" />
    <meta name="description" content="Typescript UI Controls" />
    <meta name="author" content="Syncfusion" />
    ....
    ....
</head>

<body>
     <!--container which is going to render the Accumulation chart-->
     <div id='element'>
     </div>
</body>

</html>

Now, import an accumulation chart component in your app.ts to instantiate the accumulation chart, and append the accumulation chart instance to the #element [src/app/app.ts]

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

// initialize Accumulation Chart component
let chart: AccumulationChart = new AccumulationChart();

// render initialized Accumulation Chart
chart.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 { AccumulationChart } from '@syncfusion/ej2-charts';
let piechart: AccumulationChart = new AccumulationChart({
    series: [
        {
            dataSource: [{ x: 'Jan', y: 3 }, { x: 'Feb', y: 3.5 }, { x: 'Mar', y: 7 }, { x: 'Apr', y: 13.5 },
            { x: 'May', y: 19 }, { x: 'Jun', y: 23.5 }, { x: 'Jul', y: 26 }, { x: 'Aug', y: 25 },
            { x: 'Sep', y: 21 }, { x: 'Oct', y: 15 }],
            xName: 'x',
            yName: 'y'
        }
    ]
}, '#element');

Now, use the npm run start command to run the application in the browser.

npm run start
