  Exploratory graphics

The exploratory utility is specifically useful for the visual display of trends in longitudinal studies with continuous outcome variables.

Open allage.ss3 from the examples\count folder.

The selection shown above invokes the New Graph dialog box as shown below.

From the graph below, we see an approximately linear trend over time.

To investigate further, a plot for each level-2 unit (Drug) is requested:

The following graphs are a subset of the graphs for the 18 drug types.
