This example produces two pie charts that shows energy sources by year. Both charts are displayed on one page and are arranged two across. The program uses the CLOCKWISE option to arrange the slices, which begin at the 12 o'clock position and proceed clockwise in alphabetic order of the midpoint.

The chart statistic is suppressed and the midpoint label and the percent of the chart statistic are displayed outside of the slice.

A different color is defined for each energy type. The patterns are assigned in order of midpoint value. Some colors do not appear because the slices they represent are grouped into the OTHER slice, which is assigned the eighth color, red.
