  1. These curvy lines seem a bit misleading to me. Are they some sort of automatic curve interpolation from Excel?

  2. I can't see any good reason for the curves either, so, yeah, this looks like a case of bad graphing options in Excel. You see this a lot in corporate presentations.

    On a related topic, I don't care for the wording "function of time" here. "By time" or "broken down by time" would be simpler and more accurate.
