Hi Nick,
Actually, the functionality is there, with some changes, though. The aggregate functions are now defined per series, allowing you to use one ChartDataSource for all series, while applying different sampling functions. To achieve this, please create a class, which inherits from the series you use and override the corresponding Get*AggregateFunction method. E.g. for categorical series you would need to override GetValueAggregateFunction and (if needed) GetCategoryAggregateFunction and for ScatterPointSeries, ScatterLineSeries or ScatterAreaSeries you have to override GetXValueAggregateFunction and GetYValueAggregateFunction.
Please, accept our apologies for not including this in our documentation. We are aware of the problem and we aim to fix it.
Best regards,
