Pie Charts / Binding to remote data
1024x768 screen resolution trends
The Telerik MVC Chart offers two ways of data-binding:
- Server - the chart will bind to a supplied model
- Ajax - the chart will perform Ajax requests to populate its series
For remote data binding you need to specify a remote endpoint or web service returning data in JSON/JSONP format and utilize the DataSource as a mediator between the chart and the underlying data. To make the connection to the remote endpoint and process the data properly, the data source needs information about the web service URL(s), the request type, the response data type, and the structure (schema) of the response, in case it is more complex than a plain array of objects.
In this example the chart fetches its data from a MVC controller assigned via the DataSource read configuration. You can find more information about the data-binding capabilities of the MVC chart in this help article.
