Not sure about the "better view". I actually prefer the first plot posted on 09/10, since it does not chop off the time axis at the bottom.
I assume all these roasts are for the Guatemala Chihen (which I haven't roasted). I am surprised how far you are roasting this, 4:00 after start of 1st crack (and a temp increase of 47F). I think most of the Guat character would be gone by that point.
About six years ago, I would roast Guats to about 2:30 after start of 1st crack. My recent roasts usually eject the beans closer to 2:00 after start of 1st crack.
