Cumulative Sum Control

Exclude a Sample from Subgroup Calculations

A sample can be excluded from subgroup calculations. The cumulative sum control of the .Net Analytics package is of the following type:

Cumulative Sum (CuSumChart)

The series class of the cumulative sum chart is:

CuSumSeries

The subgroup class of a cumulative sum series is:

CuSumSubgroup

and the sample class is:

CuSumSample

The following property is used for excluding a sample:

ExcludeFromCalculation

The first step is to include the necessary namespaces for the controls and add a new series.

Exclude a Sample from a Subgroup

Below, we will exclude a Cumulative Sum sample (named cssSample in the examples below), from a Cumulative Sum subgroup (named cssSubgroup in the examples below) of a Cumulative Sum series (named cssSeries in the examples below). The process is similar for the other charts listed above:

[Visual Basic]

' Exclude the sample
cssSample.ExcludeFromCalculation = True

                  

                  ' Another alternative is to 
                  exclude the ith (2 below) sample directly from the subgroup

                  cssSubgroup(2).ExcludeFromCalculation = True

                  

                  ' A third alternative is to exclude the ith (2 below) sample from the jth (1 
                  below) subgroup of the series

                  cssSeries(1)(2).ExcludeFromCalculation =  True

[Visual C#]

// Exclude the sample
cssSample.ExcludeFromCalculation = true;

                  

                  // Another alternative is to 
                  exclude the ith (2 below) sample directly from the subgroup

                  cssSubgroup[2].ExcludeFromCalculation = true;

                  

                  // A third alternative is to exclude the ith (2 below) sample from the jth (1 
                  below) subgroup of the series

                  cssSeries[1][2].ExcludeFromCalculation = true;
