In addition to the possibility to add your own calculated columns or custom expressions to an analysis, a business author might also have access to data functions that have been created by a script author using Spotfire Analyst and saved in Spotfire 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, see the following sections:

• What are data functions?
• Running data functions in Spotfire web clients
• Data functions in the Data canvas
• Interactive tuning of data functions
• The f(x) flyout
