AFValues.PlotValues Method

public AFValues PlotValues(
	AFTimeRange timeRange,
	int intervals
)

Public Function PlotValues ( 
	timeRange As AFTimeRange,
	intervals As Integer
) As AFValues

Dim instance As AFValues
Dim timeRange As AFTimeRange
Dim intervals As Integer
Dim returnValue As AFValues

returnValue = instance.PlotValues(timeRange, 
	intervals)

public:
AFValues^ PlotValues(
	AFTimeRange timeRange, 
	int intervals
)

member PlotValues : 
        timeRange : AFTimeRange * 
        intervals : int -> AFValues 

Parameters

timeRange

Type: OSIsoft.AF.TimeAFTimeRange
The bounding time range for the plot values request.

intervals

Type: SystemInt32
The number of intervals to plot over. Typically, this would be the number of horizontal pixels in a horizontal trend.

Return Value

This method is a client side calculation on the AFValues collection previously retrieved.

For each interval, the data available is examined and significant values are returned. Each interval can produce up to 5 values if they are unique, the first value in the interval, the last value, the highest value, the lowest value and at most one exceptional value (bad status or digital state).

For performance reason, this method assumes that events (timestamp) in AFValues are in order (monotonic), either in forward or reverse direction. The user can programmatically utilize the default extension method to AFValues if the events are not in order.
