I cannot find a way to export aggregated data to excel. Either from a graph menu on by right-clicking on part of a graph only shows or exports the underlying raw data and not the aggregated ones. Is there a way to do so?
In the view with the aggregated data, click "View tools" (or just "Tools" in Omniscope 2.6+) and choose "Export view data". A save dialog will open with the "Data" tab selected, with Excel chosen by default, and "In aggregated form" ticked on the right.
