has an alternate solution for
hierarchical dimension representation in cross tabulation visuals.
The following steps demonstrate how to create and configure a de facto
dimensional hierarchy on the shelves of a cross tabulation visual. We are using
dataset World Life Expectancy [data source
samples.world_life_expectancy], to build a cross tabulation
table that can switch between representations at three different levels of data
granularity.
Start a new cross tabulation visual on the World Life Expectancy dataset.
For more information, see Cross tabulation.
Populate the shelves from the available Fields under
Dimensions and Measures in the
Data menu.
Under Dimensions, select
un_region and drag it over the
Dimensions shelf. Repeat with
un_subregion and country, adding
them under un_region. Note that your placement of these
fields is from the largest to the smallest, top to bottom.
Under Measures, select
population and drag it over
Measures shelf. Ensure that the default
aggregation is sum(population).
On the Row shelf, select the un_region
field and select Enable Expansion option in the Field
Properties panel.
On the Row shelf, on the un_subregion and the
country field, click the Down arrow icon, and
select Enable Expansion.
Click Refresh Visual.
The cross tabulation table appears with a Plus icon in
the un_region, un_subregion, and
country columns. This indicates that you can expand the
data in these columns.
The sum(population) column shows the combined population for all
un_regions.
To see more details, expand the un_region column of the visual by
clicking the Plus icon under the column header.
Expand the un_subregion column of the visual by clicking the
Plus icon in the field next to one of the
un_region. We chose to expand Africa.
When you expand Africa, it generates a complete tabulation aggregated by
un_subregion.
Expand the country column of the visual by clicking the
Plus icon in the field next to one of the
un_subregions. We chose to expand Middle Africa.
When you expand Middle Africa, it generates a complete tabulation aggregated by
country.
Change the title to Hierarchical Cross Tabulation of
Population.
At the top left corner of the Visual Designer, click
Save.
