Just like normal DAT files, you can also append HD queries or time period queries to HD queries, time period queries or DAT files that are already open in order to display longer periods of time.

It only makes sense to append to a DAT file if the signal structure of the DAT file and the HD record is the same.

1. To append a query, select Append HD Query in the Historical Data menu or in the context menu of the signal tree.

   
   

   

   
   

   The configuration dialog for the HD query opens.

2. Optionally, set a different query period and execute the query.

   The new query result is nested in the signal tree.

	To ensure a timely appearance in the graphs, make sure that the option Synchronize files on recording time is enabled in the X-axis settings.
