It would be nice to be able to use visuals in a multi-faceted way to giving the viewer of the dashboard the ability to select the measure being used. Currently if we want to be able to view Sales Amount, Cost Amount, Profit Amount, and Profit % the designer would need to add this as 4 different visuals. Adding a selector for the end user of the dashboard to be able to select Sales Amount and have the visual show this, then click on Profit % and have the visual update to reflect that new measure would be amazing. It would add a ton of functionality and flexibility to the tool.
