How to use ejChart with angular JS in ASP.NET Web Forms Charts?
Essential Chart supports two-way binding by using angular JS plugin. All the properties in the chart can be bound with HTML elements. Essential Chart requires the JavaScript file ej.widget.angular.min.js to support angular JavaScript. Refer to Common Angular Binding for more information on using angular JS with Essential JavaScript controls.
Required scripts
The CDN link for the scripts required is shown in the following table:
<script src="http://code.jquery.com/jquery-1.10.2.min.js" type="text/javascript"></script> <script src="http://ajax.aspnetcdn.com/ajax/globalize/0.1.1/globalize.min.js"></script> <script src="http://cdn.syncfusion.com/12.4/js/web/ej.web.all.min.js" type="text/javascript"></script> <script src="https://cdnjs.cloudflare.com/ajax/libs/angular.js/1.3.11/angular.min.js"></script> <script src="http://cdn.syncfusion.com/js/ej.widget.angular-latest.min.js"></script>
The following code example illustrates the use of Essential Chart with angular JS. Note that it is mandatory to use the module, ejangular, and the directive, ej-chart, for rendering the Essential Chart because the directive, ej-chart, is used to render the Chart inside the container and this directive is present only in the ejangular module.
All the properties in the Chart can be bound with another control by using angular JS. The property name should be prefixed with e- to support one-way or two-way bindings; otherwise, the angular binding does not work on that property.

Note:
A new version of Essential Studio for ASP.NET is available. Versions prior to the release of Essential Studio 2014, Volume 2 will now be referred to as a classic version. The new ASP.NET suite is powered by Essential Studio for JavaScript providing client-side rendering of HTML 5-JavaScript controls, offering better performance, and better support for touch interactivity. The new version includes all the features of the old version, so migration is easy.
The Classic controls can be used in existing projects; however, if you are starting a new project, we recommend using the latest version of Essential Studio for ASP.NET. Although Syncfusion will continue to support all Classic Versions, we are happy to assist you in migrating to the newest edition.
For current customers, you can check out our components from the License and Downloads page. If you are new to Syncfusion, you can try our 30-day free trial to check out our other controls. If you have any queries or require clarifications, please let us know in the comments section below.
You can also contact us through our support forums, Direct-Trac, or feedback portal. We are always happy to assist you!
