Interactions are used
to direct a report viewer’s attention to specific results in
a report. The interaction view in the designer interface enables report
authors to specify which interactions they would like to add to tables,
graphs, and gauges in a report.
There are two types
of interactions:
filter
is used to restrict
the data that is returned from a query to a data source. Filters are
simply a set of rules, or conditions, that you specify to subset the
data that is displayed in a table or graph. The goal is to display
only the data that you need to see to perform your analysis.
brush
is short for data
brushing, which enables you to show the same data selected
simultaneously in two or more tables, graphs, or both. The brushed
data has the same appearance in each object, which makes the data
easily apparent to report viewers.
Typically, graphs are
the source of an interaction, with the exception of scatter plots.
Tables, graphs, and gauges can be the target for an interaction. However,
tables, gauges, and scatter plots cannot be the source of an interaction.
