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.
