If the Codes within the Events you want to synchronize are not the same in each DataSet, or the synchronization point has not been coded at all (so the Sync to Code command cannot be used), there are alternative ways to shift the DataSets the way you need to.
Sync on an Event
You can pick any Event to use as your time shift base. You can even choose between using the start time or the offset of the selected Event, as your synchronization time:
▪Right-click the Event of your choice in DataSet 1.
▪Select DataSet Time shift > Shift to start time of current element or Shift to offset of current element (depending on your needs), from the shortcut menu.
INTERACT now enters the DataSetOffset command into the transcription field of DataSet 1 like this: DataSetOffset100ns 684000000 > 0
▪Select the 'key' Event in DataSet 2 and continue as described above.
▪Repeat this action for each DataSet you want to virtually move.
▪Click Analysis - Evaluation - Timeline Chart 
, to recreate your Timeline Chart.
▪Click Align on Zero 
, to hide all Events that now lay virtually before zero. This is important to get the correct statistics.
IMPORTANT: Only if you click the Align on Zero icon (to hide all Events logged before the new, shifted start time) those preliminary Events are no longer present in the statistics!
| TIP: | If you did not log your synchronization time as an Event, manually add an Event using  and enter the required time information. - Then right-click this Event to set the required offset value in 100 Nanoseconds. |
Alternate Synchronization point
If you do not want to omit all statistics on Codes coded before the 'Key' Event used, you can manually change the DataSet-Offset command:
▪Select the DataSet line of which you want to change the offset value.
▪Look at the Transcription field at the bottom of the window. Here the current offset command looks something like this: DataSetOffset100ns 684000000 > 0
▪Change the '> 0' part of the command to any point in time, written in 100Nanoseconds!
Example: if you are interested in the last 30 seconds before this command was given, replace the > 0 by > 300000000, resulting is something like this:
DataSetOffset100ns 684000000 > 300000000
