If you have more than one nominal or ordinal column selected in the Data Filter, this option clears any other selections before making a new selection. For example, using Big Class.jmp, suppose that you have the columns sex (nominal) and age (ordinal) in your Data Filter. If you have males (M) selected for sex, and you click on an age group, say age 12, your selection of males will be automatically cleared. This means that selecting age 12 is not conditional on selecting males. Conversely, if you turn off Auto clear, you can then select both males and age 12 at the same time. Auto clear is on by default.
Enables you to control the AND and OR behavior of multiple groups of column filters. See Grouped by AND in Data Filters.
Sequentially highlights the values of a single variable in the data table. See Animation in Data Filters.
The following example illustrates how the Conditional option helps show the subcategories clearly, without the extra categories that do not belong.

The cities that are in Ohio and in the Midwest region are selected in the data table. In the Data Filter window, only Midwestern states appear in the State list, and only cities in Ohio appear in the cities list. See Figure 8.11.
Figure 8.11 Using the Conditional Option
The bracketed number in front of the column name indicates the order in which the column values were selected. In Figure 8.11, Region was selected first, so it has a [1] in front of the column name. State was selected second, so it has a [2] in front of the column name.
You can reverse the AND and OR behavior by selecting Grouped by AND from the red triangle menu.

To use the animation feature, from the red triangle menu next to Data Filter, select Animation. Then select the variable that you want to animate. The highlighted frame around the variable indicates which variable is selected for animation.
Figure 8.14 Animation Control Panel in the Data Filter
The Animation Control panel (Figure 8.14) contains the following controls:
) starts and pauses the animation. After you start the animation cycles, the button changes to a pause button (
). By default the animation begins with the first value of the topmost variable.
) moves the animation backward one cycle. Click more than once to go backward more than one cycle.
) moves the animation forward one cycle. Click more than once to go forward more than one cycle.|
