Stack Columns
Example of Stacking into More than One Column
Suppose that a researcher has data on blood pressure readings. The readings were taken over three days:
Monday, Wednesday, and Friday. Three readings were taken each day, at 8am, 12pm, and 6pm.
1. Open the Blood Pressure.jmp sample data table.
Each BP (blood pressure) column is delineated according to the date and time. The BP 8M column
corresponds to readings that were taken at 8am on Monday. The BP 12W column corresponds to
readings that were taken on 12pm on Wednesday, and so on. The researcher wants to stack all of the
blood pressure columns into three columns that correspond to each day: Monday, Wednesday, and
Friday.
2. Select Tables > Stack.
3. Select all of the BP readings and click Stack Columns.
The order of the columns reflects the way that the columns in the series should be grouped.
4. Select Multiple series stack.
5. Next to Number of Series, type 3.
6. Because you want to stack the columns vertically, select Contiguous.
7. Rename the Stacked Data Column from Data to BP (for blood pressure).
8. Rename the Source Label Column from Label to Day.
