Interview cards

What are field parameters and when do you use them? A field parameter is a table of measures or columns with a slicer. Users choose which field a visual shows, so one chart replaces many.

How does a what-if parameter work? It creates a table of numbers (GENERATESERIES), a slicer, and a measure with SELECTEDVALUE that returns the chosen number. Other measures use that value.
