Parameters
- frame
- Type: Extreme.DataAnalysisDataFrameDateTime, C
A data frame. - recurrence
- Type: Extreme.DataAnalysisRecurrence
The recurrence pattern to resample to. - aggregators
- Type: System.Collections.GenericIDictionaryC, AggregatorGroup
A dictionary that maps column keys to aggregators. - direction (Optional)
- Type: Extreme.DataAnalysisDirection
Indicates whether the entries in
frame's row index should be taken as
the start (Forward) or end (Backward) of a sampling interval.
Type Parameters
- C
Return Value
Type:
DataFrameDateTime,
CA new data frame with a column for each entry
in
aggregators which is the result of resampling
the column with the entry's key using the specified recurrence pattern
and the aggregator in the entry's value.
The order of the columns is preserved.
Usage Note
In Visual Basic and C#, you can call this method as an instance method on any object of type
DataFrameDateTime,
C. When you use instance method syntax to call this method, omit the first parameter. For more information, see
Extension Methods (Visual Basic) or
Extension Methods (C# Programming Guide).
