Spotfire Ideas Portal
The Spotfire expression language is very powerful and versatile and it would be quite useful if it was possible for a visualization Mod to send Spotfire an expression e.g. Sum([Sales]) and getting value back calculated over the subset of the data that the Mod is working on. The behavior could be similar to the way calculated values in text areas work and could open up use cases for Mods that requires you to go beyond a single data view without requiring any more complicated configuration for the end user.
