• a browsing TimeLine control: the TimeLine control will be linked to a data file or to a query. In this case, the data file contains the characteristics of the events.
• a TimeLine control on source: the TimeLine control will be linked to a variable (a class instance in most cases). In this case, the class lists the events and their characteristics.

Creating a browsing TimeLine control

1. Open the control description window ("Description" from the popup menu).
2. In the "Content" tab, select "File/Query" and select the data source used. 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.
   Remark: If the associated data file does not directly contain the corresponding item, you have the ability to perform a multi-file link.
4. Validate the description window of the TimeLine control. The TimeLine control is a browsing timeline.

Creating a Timeline on source control

1. Open the control description window ("Description" from the popup menu).
2. In the "Content" tab, select "By variable" and select the data source used (class, ...).
3. Associate the different elements (members of the class for example) of the data source with the characteristics of the event. The elements preceded by a star are mandatory.
4. Validate the description window of the TimeLine control. The TimeLine control is a timeline on source.
