Box and Whisker Plot Control

Build Subgroups

This page describes how to build subgroups the box and whisker plot. The box and whisker control of the .Net Analytics is the following type:

Box and Whisker (BoxWhiskChart)

The subgroups can be built for the box and whisker plot using the following methods:

Subgroup Size: dependent upon the number of samples in the chart
Code: a parameter of samples

The first step is to include the necessary namespaces.

Add Samples and Build Subgroups

Below, we will add samples to a Box and Whisker chart (named bwPlot in the examples below) and build the subgroups using subgroup size. We will add six and samples and use a subgroup size of 2 to get three subgroups:

[Visual Basic]

' Create new samples
bwPlot.Samples.Add(10)

                bwPlot.Samples.Add(12)

                bwPlot.Samples.Add(13)

                bwPlot.Samples.Add(15)

                bwPlot.Samples.Add(9)

                bwPlot.Samples.Add(8)

                

                ' Build the subgroup

                bwPlot.SubgroupSize = 2

                bwPlot.BuildSubgroupMethod = BuildSubgroupMethods.BuildBySubSize

[Visual C#]

// Create new samples
bwPlot.Samples.Add(10);

                bwPlot.Samples.Add(12);

                bwPlot.Samples.Add(13);

                bwPlot.Samples.Add(15);

                bwPlot.Samples.Add(9);

                bwPlot.Samples.Add(8);

                

                // Build the subgroup

                bwPlot.SubgroupSize = 2;

                bwPlot.BuildSubgroupMethod = BuildSubgroupMethods.BuildBySubSize;

After the samples have been added, and the subgroups built, the resulting chart should look similar to the following:
