I have to admit upon looking at your "improved" map version, I immediately thought red (generally negative) would have indicated a decline and blue an increase. What confused me even more was the fact that negative values are going upwards and blue downwards in your legend. Otherwise, thanks for the insight in your article.


My natural assumption on the red vs blue in this case was more related to a heat map - red for more activity(hotter), blue for less(cooler).


Jim and jlbriggs: I went through that exact sequence when I created the map. First I was with Jim as I associate red with negative numbers. Then I realized that red can also mean hot, like jlbriggs said. A different color scheme altogether can remove this confusion.
