The GCHART Procedure

Example 10: Ordering and Labeling Slices in a Pie Chart

Procedure features:
PIE statement options:
CFILL=
MIDPOINTS=
PERCENT=ARROW
SLICE=ARROW
SUBGROUP=
VALUE=NONE
Sample library member: GR13N10

This example produces a pie chart of sources of energy production for 1995. The labeled slices represent the percent of total production for each source. Instead of the sum statistic, each slice displays the percent each midpoint contributes to the whole pie. Arrows connect the midpoint labels to the slices, which are arranged by the MIDPOINTS= option so that the small slices are not next to each other and their labels do not overlap.
