Pareto Control

Null Values in a Group

A group is composed of multiple samples. In some cases, sample values may not be known. This page describes how to handle null values. The pareto control of the .Net Analytics package is of the following type:

Pareto (ParetoChart)

The series class of the pareto chart is:

ParetoSeries

The group class of a pareto series is:

ParetoGroup

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

Add Null Values to a Group

Below, we will add values, including null values, to Pareto groups of a Pareto chart (named pcChart in the examples below). The process is similar for the other charts listed above:

[Visual Basic]

' Create a new group

                  Dim pgGroup As New ParetoGroup()

                  ' Add some sample values to the group

                  pgGroup.Add(0.4)

                  pgGroup.Add(0.2)

                  pgGroup.Add(0.5)

                  ' Exclude the last sample from calculations of the group

                  pgGroup(2).ExcludeFromCalculation = True

                  ' Add the group to the first series

                  pcChart.SeriesCollection(0).Add(pgGroup)

[Visual C#]

// Create a new group

                  ParetoGroup pgGroup = new ParetoGroup();

                  // Add some sample values to the group

                  pgGroup.Add(0.3);

                  pgGroup.Add(0.1);

                  pgGroup.Add(null);

                  // Add the group to the first series

                  pcChart.SeriesCollection[0].Add(pgGroup);

                  

                  // Create another new group

                  pgGroup = new ParetoGroup();

                  // Add some sample values to the subgroup

                  pgGroup.Add(0.4);

                  pgGroup.Add(0.2);

                  pgGroup.Add(0.5);

                  // Exclude the last sample from calculations of the group

                  pgGroup[2].ExcludeFromCalculation = true;

                  // Add the group to the first series

                  pcChart.SeriesCollection[0].Add(pgGroup);
