GetRawItemData Method (IDBAPlugin)

Reads the raw data points in the given time range from the database into a DataPoint array. At least one data point before and after the time range should be included in the returned array, because a bounding value may be requested or interpolation needed. Excess data doesn't harm, it will be ignored in the base layer data processing. This method needs NOT be thread safe. The returned data MUST be sorted for increasing timestamps

Syntax

Visual Basic
C#

DataPoint[] GetRawItemData( 
   ItemInfo item,
   DateTime startTime,
   DateTime endTime,
   int maxValues,
   bool bounds
)
