Pie
This is one of the most commonly used types of chart. The dialog boxes are
similar to those presented above for bar charts. The slices of each pie can
represent different categories of a variable or different variables. Figure 70
shows an example of a pie chart that describes the competitive level of a group
of pupils (summaries for group of cases).
In order to show the percentages or the values of each slice, double click to
edit the chart. Select Options from the Chart menu. At the top of Dialog box 117
you can arrange the orientation of the first slice. You can also specify a
percentage value to be the minimum threshold for depicting a variable in a
separate slice; all variables below this specified value will be considered too

gives names to the slices. You can also ask for the values and percentages of the
slices. Select Edit Text to change the labels of the slices. Click Format.
In Dialog box 118 you can specify whether the labels should be positioned
inside or outside the pie. For labels positioned outside the pie, connecting line
for outside labels connects the labels with their respective slices. Arrowhead on

of the values in the slices. If you want to keep the slices separated from each
