Project Documentation tab: can you 'freeze' a graph so another can be added and compared against?

[OKors]

I've been using the Project Documentation view recently to quickly compare dc signals against changes that I make to an electrical system. What I'm trying to do is capture a few seconds of a DC signal, stop acquisition, make a change in the system, then capture a few more seconds of the same signal and compare the two.
Project Documentation view is nice because I can drag the graphs onto the document for quick on the fly comparison.

Problem is, I drag a acquired signal's graph onto the document expecting the waveform to 'freeze' so that I can capture another segment of data and drag that graph onto the document for comparison. But once I acquire this second burst of data the first graph captures the live waveform, overwriting the baseline waveform I'm trying to compare against.

Is there a way to screencapture or freeze the graph so that multiple graphs can be stacked within the document form without them all updating?

Hi OKors,

I’m not sure if you can do exactly what you want. If it were me, I would take the first reading, then save it to an LVM file, then take the second reading, store that to an LVM file, then load the files to compare.
