Installation and Configuration

  • To get started with accumulation chart component, clone the Essential JS 2 quickstart project, and install necessary packages by using the following commands:
git clone https://github.com/syncfusion/ej2-quickstart.git quickstart
cd quickstart
npm install
  • Map the Accumulation chart packages in system.config.js configuration file.
System.config({
    paths: {
        'syncfusion:': './node_modules/@syncfusion/',
    },
    map: {
        app: 'app',

        //Syncfusion packages mapping
        "@syncfusion/ej2-base": "syncfusion:ej2-base/dist/ej2-base.umd.min.js",
        "@syncfusion/ej2-data": "syncfusion:ej2-data/dist/ej2-data.umd.min.js",

    },
    packages: {
        'app': { main: 'app', defaultExtension: 'js' }
    }
});

The project is preconfigured with common settings (src/styles/styles.css, system.config.js) to start with all Essential JS 2 components.

Add Accumulation Chart to the Project

Add HTML div elements in your index.html. [src/index.html] for 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" />

    <script src="https://cdnjs.cloudflare.com/ajax/libs/systemjs/0.19.38/system.js"></script>
    <script src="systemjs.config.js"></script>
</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.

var piechart = new ej.charts.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');

 }   
        </script>

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

npm run start
