Large Data Sets

While there is no limit to the number of observations that can be read from an input data set, the maximum number of Pareto categories that can be read is 32,767. This limit is a practical issue only if you are creating a restricted Pareto chart from a large data set, because the number of categories that can be displayed is limited by the resolution of your graphical display. The number of categories that can be read is limited by the amount of memory available, since the levels are stored in memory. If you run out of memory, you should first reduce the data with the FREQ procedure.
