I’ve been neglecting to announce my Win-Vector posts here — but I’ve not stopped writing them. Here are the two most recent:
In which I explore how to make what Matlab calls a “scatterhist:” a scatterplot, with marginal distribution plots on the sides. My version optionally adds the best linear fit to the scatterplot:
I also show how to do with it with
