Time Series Controls

Add a New Sample to a Subgroup

Samples for the subgroup based control charts must be added to a subgroup. The time series controls of the Silverlight Analytics package that are based on subgroups include the following:

XbarControl (XbarControl)
RangeControl (RangeControl)
StdDevControl (StdDevControl)

The series classes of these respective charts are:

The subgroup classes are:

and the sample classes are:

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

Add a Sample to a Subgroup

Below, we will add a sample to a Xbar subgroup (named xsSubgroup in the examples below) and to a Xbar series (named xsSeries in the examples below). The process is similar for the other charts listed above:

[Visual Basic]

' Create a new sample
Dim xsSample As New XbarSample(0.091)

                  ' Add the sample to the subgroup
xsSubgroup.Add(xsSample)

' An 
                  alternative is to add the sample directly to the subgroup
xsSubgroup.Add(0.877)

                  

                  ' Another alternative is to add the sample directly to the series at the ith 
                  (0 below) subgroup

                  xsSeries(0).Add(0.775)

[Visual C#]

// Create a new sample

                  XbarSample xsSample = new XbarSample(0.091);
// Add the sample to the 
                  subgroup
xsSubgroup.Add(xsSample);

// An alternative is to add the 
                  sample directly to the subgroup
xsSubgroup.Add(0.877);

                  

                  // Another alternative is to add the sample directly to the series at the ith 
                  (0 below) subgroup

                  xsSeries[0].Add(0.775);
