This example shows the actual amount of energy that is produced by each source for 1985. It displays the chart statistic inside each slice and uses a legend instead of slice labels to identify the slices. Pattern colors are assigned explicitly to each energy source.

All of the variables with midpoint values less than or equal to 5 percent of the total (in this case, biofuels, geotherm, and hydro) are grouped into one slice labeled "Other." The slices are ordered from largest to smallest based on the statistic value. Although the "Other" slice is always last, it is in this case also the smallest.
