I the 118 is for the number of years that records have been kept so 118 reflects the high for all of the years, and 1 would be the lowest for all the years, I am guessing. But of course you shouldn't have to guess.

Also good point about aggregation and the loss of information.


Thanks for the comment. I made me realize I said 1 is the hottest "month", by which I meant hottest "year" or year with the hottest March. I've fixed that now.

Nice post, I took your heatmap suggestion and scraped the data to do it. Full post and heatmap here: http://drunks-and-lampposts.com/2012/04/22/118-years-of-us-state-weather-data/


Mark: Thanks so much for completing the redo. I've included it in my post above. For your second chart, I suggest that you standardize the temperature data by state first. Then you'd find a lot of red on the right.

NOAA creates some of the worst graphics in science. It's rather depressing as they also have some of the richest datasets. Have you seen this abomination?
