Parameter type settings determines how the parameter is displayed to end users.
There are two or three parameter types to choose from - depending on whether the parameter will be used to inject text or numeric values.
- Numeric: Discrete, Continuous and Free Input
- Text: Discrete or Free Input
Static Discrete parameters are used when the user needs to pick something from a definitive list of items. They can be used for driving both text and numeric selections throughout the application - including formulas, logic and lists. They can also be global in scope, or attached to a specific data model.

Static Continuous parameters are used when the user needs to pick something from a list of items, but the listing is based on a numerical range that has only been described by that range. In this way, continuous parameters contain a 'soft' listing of items. As such they can be used for driving only numeric selections throughout the application. They can also be global in scope, or attached to a specific data model.

'Free Input' or free form parameters enable users to enter input into the application using any acceptable value rather than choosing from a predefined list of choices (either statically or dynamically set). For instance, if you are building a visualization to show the top n items in the query, the user can simply type what ever number of items they would like to see rather than pick from a predefined list of choices (like Top 3, Top 10, and Top 25).
