You can display trend queries in the Overview window. On trend queries in this window, you cannot perform calculations. However, the Overview window has features that are not available for trend queries in the main window of the signal display. The Overview is particularly useful if you start a database query that searches for extracted files that correspond to the data points of the trend query results in the Overview. You can open the original DAT files that correspond to these extracted files here (drill down function).

You can only erase a query result in the Overview window with a new query.
