Ok, I'll be honest. Every time I look at one of these "2 joined dots" charts, it seems to reflect the opposite of what's claimed. Am I missing something obvious?

Never mind. I've looked again and worked it out. I was missing something obvious to chart makers, but not at all clear to this particular chart observer. AFAIAC, it's a terrible way to graphically display the intended information.

I want 2 plots, one above the other, showing actual and predicted for each year. Easy.
