To create an interaction
using data brushing:
-
Add the report objects
that you want to use to the canvas. For example, you might have a
bar chart, a line chart, and a list table.
-
Select the
Interactions tab.
-
Click
Interactions
View on the
Interactions tab
to switch to the interactions view. You can also select
View Show Interactions.
-
In the interactions
view, draw a connection between the source and target report objects.
When you have created an interaction, the
is displayed between the report objects.
-
Right-click
. Then, select
Interaction
TypeBrush.
Interaction Type Menu with Brush Selected
The filter icon changes
to
.
-
Click
Close.
The new interaction (or interactions) appears on
Interactions tab
in the right pane.
Select data in the source
report object to brush data in the target report object (or objects).
In the following example, the stuffed animal product line was selected
in the bar chart. Simultaneously, the line chart and the crosstab
highlight the same data.
A Data Brushing Example with a Bar Chart, a Line Chart, and
a List Table
Note: If a graph contains a frequency
measure, then a crosshatch pattern indicates when it is selected or
brushed.
The brush interaction
between controls behaves differently than a brush interaction between
tables and graphs. When there is a brush interaction between controls,
instead of highlighting or selecting the values in the other control,
the values that match are moved to the top of the control, and the
values that do not match are grayed out. If a frequency data item
exists, then the frequency value is updated.
Here is an example
of a report on cars with three list controls:
Three List Controls with Brush Interactions
The first list contains
three countries listed as the
Origin.
The second list contains six types of vehicles. The third list contains
38 car manufacturing companies. There is a brush interaction between
the first list and the second list. There is a second brush interaction
between the second list and the third list. Look at the values in
the second list.
Example: Three List Controls in a Report
In step 1, the user
has selected
Europe as
the country of
Origin in
the first list. Notice the changes in the second list.
Hybrid and
Truck are
grayed out, and their frequency values have both changed to
0.
In the third list, all of the car manufacturers that are not located
in Europe are grayed out, and their frequency values have all changed
to
0
Example: Three List Controls in a Report with One Brush Interaction
In step 2, the user
has selected
Porsche as
the car manufacturing company in the third list. Notice the changes
in the second list.
Hybrid,
Sedan,
Truck,
and
Wagon are grayed out,
and their frequency values have all changed to
0.
