Hi Dex,
You can possibly scroll back the plotted graphics (depending on the
memory, or number of samples, reserved for the plotter channels).
Usually the memory is larger than the visible part of the graphics. You
can tell by the small horizontal scroller; if it's enabled, "there's
more than you see" ).
Cheers,
Wolf DL4YHF .

This evening I was watching HGA22 with SpecLab plotter. When I first
started the plot I noticed the signal looked as expected but when I
increased the speed I saw a sine wave shape on the plot. After
watching it for a while the sine wave pattern changed to a normal
pattern. I wish I had made more captures of the signal but I only
made one which shows the change.

FWIW if anything,
