Spotfire - Show/Hide Items trick (Visualization)

Rule Order

You can apply one or more rules to the visualization where you select either to show or hide some of the items (e.g., bars, markers or sectors) from the visualization. The order of the rules in the Show/Hide Items tab determines which rule should be applied if multiple rules affect the same item: They are always prioritized from top to bottom so the top rule will determine whether an item should be shown or hidden.

The last active rule in the list determines whether or not items that are not matched by any rule should be shown or hidden: If the last active rule hides items, then the unmatched items will be shown. If the last active rule shows items, then the unmatched items are hidden.

This may have some implications on visualizations where multiple rules are used and some of them contradict each other. For example, using the same data as above and applying Show Top 2 and Hide Bottom 2 rules simultaneously will give the following results, depending on the order of the rules:
