A subgroup is a grouping of two or more columns in a row. A DataSet is subgrouped based on the associated routine’s subgroup size characteristic. A routine is associated to a DataSet from the DataSet’s DataSource property. The subgroup size of a DataSet can be set by opening the DataSet Properties dialog Statistics tab and selecting one of the Subgroup radio button options. Enter a value in the Maximum Subgroup Size field.
A DataSet will form subgroups based on the usage that is specified when the DataSet is created or edited. For any usage that includes moving range or moving average, the subgroup size will automatically be two. For all other usage types, subgroups will be formed in a sequential non-overlapping manner (i.e. columns 1-5, 6-10, 11-15…).
CM4D will calculate and maintain statistical and summary values for subgroups.
The data for each subgroup can be easily displayed below a graph. Functions include displaying subgroup data on a chart, calculate subgroup stats, and display raw data for a subgroup.
On the Graph tab of the Annot Properties dialog, select the Show Table check box. Then, when the graph is in edit mode, open the table properties dialog and modify the Show DataSet Setup dialog to customize the table of charted values.
