• an TimeLine field file: the TimeLine field will be linked to a data file or a query. In this case, the data file contains the characteristics of the events.
• TimeLine control on variable: the TimeLine control is linked to a variable (usually a class instance).. In this case, the class lists the events and their characteristics.

Creating a TimeLine control based on a data file

1. Open the control description window (select "Description" in the context menu).
2. In the "Content" tab, select the "Data file/Query" option and choose the data source you wish to use. This data source can be:
   • a data file defined in the analysis,
   • a query of the project,
   • a query included in the window.
3. Associate the different items of the data source with the characteristics of the event. The elements preceded by a star are mandatory.
   Note If the associated data file does not directly contain the corresponding item, it is possible to create a multi-file binding.
4. Validate the TimeLine control description window. The TimeLine control is based on a data file.

Creating a TimeLine control based on a variable
