Clever use of a connected scatterplot to show rise in hot days over times for counties in the US www.nytimes.com/interactive/... Looks like heat lines radiating off a surface.

The y-axis though doesn't make sense. It should all be straight lines...

Four points in time though, so first point vertically is difference between the 1995 average compared to the 1985 average

*I mean each point in time compared against 1995 average as baseline

I don't think that is right though, a vertical line implies the given y axis number of days changed. I assume the vertical line is implying *zero* change, only when it bends right is the change positive? this is where it breaks down.... Anyway, I very much appreciate your content...

Take for instances that Cook, IL line. The first interval value is plotted at 25 and maybe 5, which means a 5 day increase?, so it should be plotted at 30 and 5, to make it agree to where the last point resides at 38 and 13 ? My accounting is here: mesonet.agron.iastate.edu/plotting/aut...
