Create the Annotate data set, BARLABEL. The MIDPOINT variable uses the values of the chart variable CITY to provide the X coordinate for the subgroup labels. The SUBGROUP variable uses the values of the variable TYPE to provide the Y coordinate that vertically positions the labels in the bar. Because no function is specified, the data set uses the default function, LABEL. The POSITION value E places the labels just below the top of each subgroup bar.
