Program Description

Set the graphics environment.

goptions reset=all border;

Define the title.

title "Types of Vehicles Produced Worldwide (Details)";

Produce the detail pie chart. This graph uses the data set entitled CARS found in the SASHELP library. The DETAIL= option produces an inner pie overlay showing the percentage that each DRIVETRAIN contributes toward each type of vehicle. The DETAIL_PERCENT= option and the DETAIL_SLICE= option control the positioning of the detail slice labels. The DETAIL_VALUE= option turns off the display of the number of DRIVETRAINS for each detail slice. The DETAIL_THRESHOLD= option shows all detail slices that contribute more than 2% of the entire pie. The LEGEND option displays a legend for the slice names and their midpoint values, instead of printing them beside the slices.
