ES5 getting started in EJ2 JavaScript Accumulation chart control

6 Feb 20269 minutes to read

The Essential JS 2 accumulation chart is provided as a separate control to simplify rendering by excluding axis-related logic. The accumulation chart uses the same core dependencies as the chart control; additional packages are required only for specific features (for example, export and compression features).

Dependencies

Below is the list of minimum dependencies required to use the accumulation 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

Setup for local environment

Follow these steps to set up your local environment.

Step 1: Create a root folder myapp for your application.

Step 2: Create myapp/resources folder to store local scripts and styles files.

Step 3: Create myapp/index.js and myapp/index.html files for initializing the Syncfusion Essential JS 2 Accumulation Chart control.

Adding Syncfusion resources

The Syncfusion Essential JS 2 Accumulation Chart control can be initialized in either of the following ways:

Using local script.
Using CDN link for script.

Using local script

You can get the global scripts and styles from the Essential Studio JavaScript (Essential JS 2) build installed location.

After installing the Essential JS 2 product build, you can copy the chart and its dependencies scripts and style file into the resources/scripts and resources/styles folder.

The following shows the path to the accumulation chart’s script and style files.

Syntax:

Dependency script: **(installed location)**/Syncfusion/Essential Studio/JavaScript - EJ2/{RELEASE_VERSION}/Web (Essential JS 2)/JavaScript/{DEPENDENCY_PACKAGE_NAME}/dist/global/{DEPENDENCY_PACKAGE_NAME}.min.js

Script: **(installed location)**/Syncfusion/Essential Studio/JavaScript - EJ2/{RELEASE_VERSION}/Web (Essential JS 2)/JavaScript/{PACKAGE_NAME}/dist/global/{PACKAGE_NAME}.min.js

Example:

Dependency script: C:/Program Files (x86)/Syncfusion/Essential Studio/JavaScript - EJ2/32.1.19/Web (Essential JS 2)/JavaScript/ej2-base/dist/global/ej2-base.min.js

Script: C:/Program Files (x86)/Syncfusion/Essential Studio/JavaScript - EJ2/32.1.19/Web (Essential JS 2)/JavaScript/ej2-charts/dist/global/ej2-charts.min.js

After copying the files, reference the chart scripts from index.html. The following HTML shows the minimal chart dependencies.


<!DOCTYPE html>
  <html xmlns="http://www.w3.org/1999/xhtml">
       <head>
            <title>Essential JS 2 Accumulation Chart</title>

            <!-- Essential JS 2 Accumulation Chart's dependent scripts -->
            <script src="resources/scripts/ej2-base.min.js" type="text/javascript"></script>
            <script src="resources/scripts/ej2-data.min.js" type="text/javascript"></script>
            <script src="resources/scripts/ej2-svg-base.min.js" type="text/javascript"></script>

            <!-- Essential JS 2 Accumulation Chart's global script -->
            <script src="resources/scripts/ej2-charts.min.js" type="text/javascript"></script>
       </head>
       <body>
       </body>
  </html>

Using CDN link for script

Using CDN link, you can directly refer the chart control’s script into the index.html.

Refer the chart’s CDN links as below.

Syntax:

Script: http://cdn.syncfusion.com/ej2/{PACKAGE_NAME}/dist/global/{PACKAGE_NAME}.min.js

Example:

Script: http://cdn.syncfusion.com/ej2/ej2-charts/dist/global/ej2-charts.min.js

The following HTML shows the minimal chart dependencies using CDN scripts.

<!DOCTYPE html>
  <html xmlns="http://www.w3.org/1999/xhtml">
       <head>
            <title>Essential JS 2 Chart</title>
            <!-- Essential JS 2 Chart's global script -->
            <script src="http://cdn.syncfusion.com/ej2/ej2-charts/dist/global/ej2-charts.min.js" type="text/javascript"></script>
       </head>
       <body>
       </body>
  </html>

Adding Accumulation Chart control

Now, you can start adding accumulation chart control in the application. For getting started, add a div element for accumulation chart control in index.html. Then refer the index.js file into the index.html file.

This document uses ej2.min.js, which includes all Essential JS 2 components and dependencies.

<!DOCTYPE html>
  <html xmlns="http://www.w3.org/1999/xhtml">
       <head>
            <title>Essential JS 2 Chart</title>
            <!-- Essential JS 2 all script -->
            <script src="http://cdn.syncfusion.com/ej2/dist/ej2.min.js" type="text/javascript"></script>
       </head>
       <body>
           <!-- Add the HTML <div> element for chart  -->
             <div id="element"></div>
             <script src="index.js" type="text/javascript"></script>
       </body>
  </html>

Place the following accumulation chart initialization code in index.js.

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'
        }
    ]
});
piechart.appendTo('#element');

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.

index.js
index.html
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');
