Getting Started

In EJ2, accumulation chart is implemented as a separate control to avoid the axis related logics. The dependencies for accumulation chart is same as chart control.

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

Setup for local environment

Refer the following steps for setup 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 Essential JS 2 Accumulation Chart control.

Adding Syncfusion resources

The Essential JS 2 Accumulation Chart control can be initialized by using 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.

Refer the below code to find location accumulation chart’s script and style file.

Syntax:

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

Example:

Script: C:/Program Files (x86)/Syncfusion/Essential Studio/15.4.30/Essential JS 2/ej2-charts/dist/global/ej2-charts.min.js

After copying the files, then you can refer the accumulation chart’s scripts into the index.html file. The below html code example shows the minimal dependency of chart.

<!DOCTYPE html>
  <html xmlns="http://www.w3.org/1999/xhtml">
       <head>
            <title>Essential JS 2 Accumulation Chart</title>
            <!-- 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, 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 below html code example shows the minimal dependency of chart.

<!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 Chart control in index.html. Then refer the index.js file into the index.html file.

In this document context we are going to use ej2.min.js which includes all the Essential JS 2 components and its dependent scripts.

<!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 chart code in the 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, 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.

            yName: 'y'
        }
    ]
}, '#element');
