Remarks
If the PivotGrid extension operates in server mode using Entity Framework, use the static GetEFDataObject method in the controller to create a model for a Chart extension and pass it to the corresponding view. The GetEFDataObject method internally creates a PivotGrid extension based on the provided settings, binds it to the specified data source and returns a chart data source provided by the created Pivot Grid.
If the PivotGrid extension operates in server mode using a LINQ provider, use the PivotGridExtension.GetLINQDataObject method. To create a chart data source from regular data, use the PivotGridExtension.GetDataObject method. To create a chart data source from OLAP data, use another overload of the PivotGridExtension.GetDataObject method that takes an olapConnectionString parameter.
