When using the Pivot table chart in the Charts tab of a dataset, you can normally set the value dimension to "Percentage scale" when selecting only one column for the Row dimension (for example Percentage scale on Count of records).
However, when you select more than one column for the Row dimension, displaying Percentage scale is no longer an option. I would love to visualize percentages by more than one row dimension.
For example, you can display percentages of Count of records by age, but not by age and country.
