You can sort a JMP data table by columns in either ascending or descending order. By default, columns sort in ascending order. You can either create a new table that contains the sorted values, or you can replace the original table with the sorted table.
If columns contain value labels, sorting is based on the actual data values, not the value labels. (See Value Labels.) However, the value labels are displayed in the sorted data table.
You can specify the order of the data in your columns using the Value Order property or the List Check property. If your sorted column uses either of these properties, the column is sorted first according to that order. See Value Order and List Check for more information.
1. Select Help > Sample Data Folder and open Popcorn.jmp.

Figure 6.5 The Sort Window
3. Highlight the names of the columns that you want to sort by. For this example, select popcorn and yield.
4. Click By to add the columns to the sort list.
The columns that you add to the list establish the order of precedence for sorting. The first column in the list is the major sort field. Each variable thereafter is sorted within the previous variable in the sort list. You can drag and drop within the By list to change the sort order.
5. Customize your sort further using the additional options. For this example, highlight yield and click the descending button.
6. Enter a name for the new sorted table in the box beside Output table name. For this example, enter sorted popcorn.
