I know I’m biased, but sometimes the graphs are a little busy for me. And sometimes it takes a while to figure out what you’re looking at, or the right line to look at. I appreciate them, but I also prefer less data per graph.
I like to be able to see the drop in output visually. It is time consuming though, because you need to set time aside and take the photographs at regular intervals. I had to set my phone alarm to keep them on schedule.
