Binding to Data Sources

Supported data sources

The igDataChart control supports the following data sources:

Data Source	Binding
`igDataSource`	Used internally by the control to manage data operations
`IEnumerable<T>`	Used to supply data from an MVC controller method

Requirements for binding

Requirements for binding to the igDataSource control vary from data source to data source. The following table lists each requirement category.

Requirement category	Requirement listing
Data structure	JSON (client side or from a web or WCF service) XML (client side or from a web or WCF service) JavaScript array IEnumerable in ASP.NET MVC
Data types	String (for category axes) Number Date

Data sources summary

The igSparkline control’s data binding is identical to that of the other controls in the Ignite UI for jQuery™ library. The way to bind data is either by assigning a data source to the dataSource option or by providing a URL in the dataSourceUrl in the event that data is provided by a web or WCF service.
