That would work, but smacks somewhat of the "separate tool for every task"
approach. Hence I think it worth mentioning another method which is to
reshape the data from wide (the repeated measures form) to long (factorial
observation form). The time point then becomes a new variable and can be
used as X in graphs. Without further reading and tests, I do not know the
advantages and drawbacks of either method. I doubt that any graph with
604 lines on it would be readily interpreted, but Stata has the power to
sample or select cases.
