Interactions are used
to direct a report viewer’s attention to specific results in
a report. Interactions allow data to be subset to reduce the amount
of data, and enables users to understand it within a particular context.
The interactions view
in SAS Visual Analytics Designer (the designer) enables report designers
to specify which interactions they would like to add to tables, graphs,
gauges, and controls in a report.
There are these 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 controls. Brushing
highlights a percentage that reflects the number of shared observations
in the data set. Brushing does not highlight a percentage that corresponds
to the aggregated value. The brushed data has the same appearance
in each object, which makes the data easily apparent to report viewers.
Tables, graphs, and
gauges can be the source of an interaction, with the exception of
time series plots. Report objects that use detail data cannot be the
source of an interaction. Controls that are used on the canvas can
also be the source of an interaction. Controls that are used as section
prompts are treated as automatic filters and are not displayed in
the interactions view.
The Interactions tab
in the right pane enables you to create interactions and links.
Here are some key points
about interactions:
Note: Interactions are available
only for report objects in the same section.
Note: Report linking is a type
of interaction. The report section that is the target of the link
is subset by the values selected in the linked report object.
