PIE Subcommand (GRAPH command)

PIE creates pie charts. A pie chart can be defined by a single function and a single BY variable or by multiple summary functions and no BY variable. A pie chart divides a circle into slices. The size of each slice indicates the value of the category relative to the whole. Cumulative functions (CUPCT, CUFREQ, and CUSUM) are inappropriate for pie charts but are not prohibited. When specified, all cases except those in the last category are counted more than once in the resulting pie.
