The following is an example: Have created 2 pivots which initially show the Total Amount and one under the other. Used the Column Selector functionality to enable a user to view the data by Total or Regions.

If the Regions is selected, the total is replaced by multiple regions however the visuals show on top of each other and do not automatically size to display all the data.

As I want the initial layout by Total not to have big gaps in it to accommodate when the user selects by Region, would be good if the visuals have a way of automatically expanding /resizing.
