This is a pretty basic concept, but I thought I'd see what everyone thought.

These charts are a sort of low-level infographic of the games each team has played, their performance, and whether they won or not.

What is unusual is that the performance level listed here is the team's efficiency differential, ADJUSTED for location, rest-day situation, and opponent. So one can see when a team had a bad day but lucked out based on a weak opponent and/or rest and location advantage.

OKC today:

Dallas today:

Note both teams are rather lucky; OKC in particular.

I seriously need to learn how to use some better visualization software. Are there any particularly good "infographic" packages that I could learn without a ton of time spent?

If you learn R you can build whatever visualization you might be able to imagine (but don't expect an easy button)!

There are pretty cool.

Easy way to quickly get a lot of information. The Dallas one is pretty amazing. Do you have/plan to do all teams, I would imagine that seeing them together would be even more interesting.

Wouldn't it make the most sense to just give each game a value of
=Actual minus Expected efficiency margin ?

Unless that's what you did -- although Dallas is so green-heavy it doesn't appear that way.

EDIT: I suppose in theory what you're doing is roughly Actual - Expected + Average, which makes a bit more sense for comparing between teams - i think I thought you were just trying to compare games within teams.

I think these are quite great. We see that Dallas underperformed vs Det and Sac, yet still won. This makes me want to see the Knicks and their winning run vs a bunch of below-average comp.

If road/home were more visibly incorporated, that might be good. A road swing or a home stand has its characteristic 'feel' to it, and the little @ symbol doesn't tie things together visually.

What we don't see at all is margin of victory (or loss). For example, one of the Mavs' best games (longest green) is vs SAS on 11-26 -- some 23 points above avg differential. This was a 9 point victory, on the road. Perhaps a black line crossing the green stripe, 9 points from the median?

Too much information becomes clutter. It's very close to just-right, as is, IMO.
A side-by-side of 2 teams about to meet, especially in playoffs, would be sweet.

Another view:

I have the average and the linear interpolation as lines:

Here's Orlando, 5 games after the trade. Things are looking up!
