Rank Filtering

Rank filtering only uses the leaf item of the breakdown when creating the ranking. Consequently, this makes the number of items consistent, regardless of the hierarchy. Note that this behavior also applies to crosstabs.

Rank Filter is available in all non-time series visualizations that use the Size or Height variable:


It is also available in the Record and Table visualizations.

Selecting By Height/Size allows you to filter the visualization based on column on the Size or Height variable:

The Top 10 values (i.e., 8951.T, 8952.T, 8959.T, 8954.T, 8957.T, 8953.T, 9022.T, 2432.T, 1605.T, 9433.T) of the leaf item (i.e., Symbol) for the next-to-leaf-node (i.e., Supersector) in the breakdown are displayed.


Example 2: Mcap(USD) as the Size variable


There are also two drop-downs displayed in the visualization:
