Setting General Options

The Chart Builder offers general options for the chart. These are options that apply to the overall chart, rather than a specific item on the chart. General options include missing value handling, chart size, and panel wrapping.

1. Click the Options tab in the side bar of the Chart Builder. (If the side bar is not displayed, click the button in the upper right corner of the Chart Builder to display the side bar.)
2. Modify the general options. Details about these follow.

User-Missing Values

Break Variables. If there are missing values for the variables used to define categories or subgroups, select Include so that the category or categories of user-missing values (values identified as missing by the user) are included in the chart. These "missing" categories also act as break variables in calculating the statistic. The "missing" category or categories are displayed on the category axis or in the legend, adding, for example, an extra bar or a slice to a pie chart. If there are no missing values, the "missing" categories are not displayed.

If you select this option and want to suppress display after the chart is drawn, open the chart in the Chart Editor and choose Properties from the Edit menu. Use the Categories tab to move the categories that you want to suppress to the Excluded list. Note, however, that the statistics are not recalculated if you hide the "missing" categories. Therefore, something like a percent statistic will still take the "missing" categories into account.

Note: This control does not affect system-missing values. These are always excluded from the chart.

Summary Statistics and Case Values. You can choose one of the following alternatives for exclusion of cases having missing values:

• Exclude listwise to obtain a consistent base for the chart. If any of the variables in the chart has a missing value for a given case, the whole case is excluded from the chart.
• Exclude variable-by-variable to maximize the use of the data. If a selected variable has any missing values, the cases having those missing values are excluded when the variable is analyzed.

Chart Size and Panels

Chart Size. Specify a percentage greater than 100 to enlarge the chart or less than 100 to shrink it. The percentage is relative to the default chart size.

Panels. When there are many panel columns, select Wrap Panels to allow panels to wrap across rows rather than being forced to fit in a specific row. Unless this option is selected, the panels are shrunk to force them to fit in a row.
