Pie

Note: If any of the rows used in constructing a slice of the pie chart are hidden and not excluded, the slice is not shown, but the position that it would occupy remains.

• For a single variable, the slice sizes the number of observations in each category.

• For two variables, the variable in the Y zone is used to size the slices according to the selected Summary Statistic. A legend appears in the Legend zone showing the values of the variable in the X zone.

Figure 3.36 Pie Options 

When you add an Overlay variable, a ring chart is constructed for each level of the Overlay variable. The outer ring represents the smallest value in the value ordering, and the inner ring represents the largest value.

Pie Style

Changes the appearance of the pie chart. For pie style descriptions, see Table 3.4.

Summary Statistic

Changes the statistic that is plotted.

Label

Adds or removes labels in the pie chart.

Variables

Shows or hides graph elements for variables, or re-orders the display of variables.

Note: These options do not apply to variables in the Group X, Group Y, Wrap, or Page zones.

Check boxes are followed by the zone designation and the name of the variable. Use check boxes to do the following:

– Show or hide the elements corresponding to a variable in a zone.

– Add or remove the effect of applying the Color, Size, Shape, or Freq variable to the variable in the zone.

Tip: If you have multiple graphs, you can color or size each graph by different variables. Drag a second variable to the Color or Size zone, and drop it in a corner. In the Variables option, select the specific color or size variable to apply to each graph.

Use arrows to re-order the display if there are multiple variables in a zone. Highlight a variable name and click an arrow to reposition it.
