Evaluate Method

This method evaluates a single argument function on the specified data series subset.

Syntax

Visual Basic
C#

'Declaration
 
Public Function Evaluate( _
   ByVal singleArgumentFormula As String, _
   ByVal subset As DataSeriesSubset _
) As Double

'Usage
 
Dim instance As DataSeries
Dim singleArgumentFormula As String
Dim subset As DataSeriesSubset
Dim value As Double
 
value = instance.Evaluate(singleArgumentFormula, subset)

public double Evaluate( 
   string singleArgumentFormula,
   DataSeriesSubset subset
)

Parameters

singleArgumentFormula

This argument supports the following string constants:

MIN	returns the minimum value contained in the subset
MAX	returns the maximum value contained in the subset
AVE	returns the average value of the subset
SUM	returns the sum of all values contained in the subset
ABSSUM	returns the absolute sum of all values contained in the subset
FIRST	returns the data series value at the first index in the subset
LAST	returns the data series value at the last index in the subset

subset

subset in the data series on which to perform the evaluation

Return Value

the result of the evaluation

Example

The following code calculates the sum of the values contained in a data series.

Visual Basic

Dim subset As DataSeriesSubset =  New DataSeriesSubset() 
subset.AddRange(0, dataseries.Count - 1)
Dim sum As Double =  dataseries.Evaluate("SUM",subset)

DataSeriesSubset subset = new DataSeriesSubset();
subset.AddRange(0, dataseries.Count - 1);
double sum = dataseries.Evaluate("SUM", subset);

Requirements

Target Platforms: Windows 7, Windows Vista SP1 or later, Windows XP SP3, Windows Server 2008 (Server Core not supported), Windows Server 2008 R2 (Server Core supported with SP1 or later), Windows Server 2003 SP2
