Quantum provides facilities for defining an axis in which various of the elements are combined to form a subaxis (or pseudo-axis) which can be cross-tabulated as any standard axis. For example, the main axis might contain all the comments made about a new type of chocolate bar. However, you also need to produce some tables which include only comments about the flavor, color or price of the product. Instead of creating a separate axis for these comments, you can just flag the appropriate elements with a group name in the main axis. The subaxes can then be tabulated in the usual way by using the group name as the axis name on the tab statement.

For information about the tab statement, see Creating a table.
