Drag output fields from the individual data series in the left pane into the Results Display area. Edit the physical order, formatting, and other properties of those fields in the same way you edit an individual data series. See Specifying Data for a Data Series for more information.
You can drag fields from the Join Conditions into the Results Display area, and (if they are an eligible datatype) from the Results Display into the Join Conditions. The Results Display does not allow the same field, from the same data series, to be dragged in twice.
If you hover the mouse over a field in the Join Conditions area or the Results Display area, popup text shows the name of the field and the data series and path that contains the field.
