GROUP= creates a separate pie for each year. In combination with GROUP=, ACROSS= draws two charts across one page. OTHER= collects all the midpoints with statistic values less than or equal to 5 percent of the total into one slice. CLOCKWISE begins drawing the slices at the 12 o'clock position in alphabetic order of the midpoint. PERCENT=OUTSIDE and SLICE=OUTSIDE display the labels outside the slices.
