In addition to the possibility to add your own calculated columns or custom expressions to an analysis, an analysis author might also have access to data functions that have been created, either by Spotfire (built-in data functions, available if you have the Spotfire Data Science license), or by a script author who can use the installed Spotfire client to create and save data functions in the library. These data functions can be used to add more advanced calculations and use scripts based on different programming languages in the analysis.

For more information about using data functions, see the following sections:

• What are data functions?
• Running data functions from the library
• Configuring data functions
• Data functions in the Data canvas
• Interactive tuning of data functions
• The f(x) flyout

For more information about authoring or editing data functions (using the installed client), see the following sections:

• Authoring data functions
• Registering a data function
• Data type mapping
