Trying to simplify what I see, as I am an absolut beginner to chart functions. But it seems to me that XVG has ceased its downward trend and is moving sideways.
And a repeating pattern happens with ...
*each spike up: on the bottom red and blue are up and yellow is down.
*Sudden drops: red and yellow are up and blue is down.
My own picture interpretation, for the lack of a better word.
