Stack Columns

You can rearrange your data table by stacking two or more columns into a single new column, preserving the values from the other columns. Or, you can stack a set of columns into multiple groups. The various ways that you can stack columns are explained in Stack Options.

To stack columns, follow these steps:

1. Select Tables > Stack.

Figure 6.8 Stack Window 

2. Highlight the names of the columns that you want to stack and click Stack Columns.

3. Customize your stacking further using the additional options.

4. Click OK.

Multiple series stack

Stacks selected columns into two or more columns. Specify the number of columns into which you want the selected columns to be stacked by entering the number into the Number of Series box. This box appears when you check the box beside Multiple series stack.

Select the Contiguous option if the series consists of adjacent columns.

See Example of Stacking Columns into More Than One Column.
