There's a problem, but not with the approval/disapproval axes. It's with the time axis.

Note that we're looking at days 0 - 1,000, that is, less than a 3-year range. This completely overlooks the second term of 2-term presidents. So, for example, we're seeing GWB's post-9/11 boom but not his later ignominy, and we're not seeing Reagan after he got the economy sorted.

But let's face it, the reason we're having our attention drawn to this right now is that we've got a president running for reelection, so it gives us exactly what we want to know.
