How to bind remote data to ASP.NET Web Forms Chart?
Essential Chart supports remote data binding (binding data in server with chart) by using Essential JavaScript DataManager. Refer to the Data Manager for information about using Essential DataManager for JavaScript.
The data manager object is assigned to the dataSource property of chart series in client-side during chart load event. The properties xName and yName of the series are assigned to the fields in data source representing the x and y values of the series respectively. The property query of series is assigned to a query object for querying the data returned by data manager.
The following cod example explains how to bind Chart to oData service.
ASP
<ej:Chart ID="container" OnClientLoad="ChartLoad" runat="server"> <Series> <ej:Series Name="Sales"> </ej:Series> </Series> </ej:Chart> <script type="text/javascript"> //Assigning URL to data manager var dataManger = new ej.DataManager({ url: "http://mvc.syncfusion.com/Services/Northwnd.svc/" }); // Object to query the data retrieved by data manager var query = ej.Query().from("Orders").take(6); //Load event of chart function ChartLoad(sender) { var chart = sender; //Assigning data manager as data source to chart chart.model.series[0].dataSource = dataManger; chart.model.series[0].xName = "ShipCity"; chart.model.series[0].yName = "Freight"; chart.model.series[0].query = query; chart.redraw(); } </script>
The following screenshot displays the output for the above code example.
