Compare Data
The interactive Difference Summary report and Different Plot indicate how rows differ between reports.
Each entry in the Difference Summary report shows which action occurred, how many rows are affected,
and the first row in which the change occurs.
In Figure 4.19, Big Class1.jmp (left) and Big Class2.jmp (right) are compared.
• The first entry in Figure 4.19 indicates that one row (N) has changed (or been replaced) in the first row
of Big Class2.jmp. When you select the entry in the Difference Summary report on the left, the entry is
highlighted in yellow, and the row flashes in the data table.
For a graphical view of the comparison, place your cursor over a colored cell in the Difference Plot.
Figure 4.19 shows that the name KATIE in Big Class1.jmp was changed to KIM in Big Class2.jmp.
The entire first row is highlighted in the Difference Plot, which tells you that all values in that row are
different.
