Specifying the Scale Axis Summary Function

1. Select options for the chart you want and click Define.
2. In the define chart dialog box, click Change Statistic. (You may need to first select Other statistic (e.g., mean) and select a variable to be summarized.)

Note: This option is available only for Bar, Line, Area, Pie, and High-Low charts and is never available when Values of individual cases is selected.
