Plot explanation
-
ORtg & DRtg: Offensive ratings (ORtg) are estimates of how many points teams score per 100 possessions, and higher is better. Defensive ratings (DRtg) are estimates of how many points teams' opponents score on them per 100 possessions, and lower is better.
-
Four quadrants: Teams in the top-left quadrant have the best net rating (estimated point differential per 100 possessions), and teams in the bottom-right quadrant have the worst. The bottom-left quadrant represents teams who are better defensively than offensively, and the top-right quadrant are those who are better offensively than defensively.
Thanks, I've already thought of some improvements for the next one!
I think if defensive rating values are inverted, the best net rating would be top-right and the worst would be bottom-left. That's probably a more familiar quadrant orientation (it reminds me of math). I might explore some green-red-orange/yellow colour shading. All suggestions are welcome :)
