Figure 9.14: Labeling Only Selected Observations
Note: Only the scatter plot is affected by selecting Label observations by on the Observations tab of the Plot Area Properties dialog box. If you create a second plot, that new plot defaults to using observation numbers to label observations.
You can also set a default label variable that is used for all plots. In the data table, right-click on a variable heading. Select Label from the pop-up menu, as shown in Figure 9.15. The values of the selected variable are displayed when you click on observations in a plot (unless that plot overrides the default).
