This scatter plot show points on the vertical axis and assists on the horizontal axies for each NBA team in 2014 (through Nov 15).
Each dot represents a game.
The least squares fit is show and the slope is given above each of the small multiples.
The Knicks have the lowest slope at about three assist per point.
At the other extreme, the Blazers are getting about three points for one assist.
The Portland Trailblazers set a new mark for first half scoring last night with 84.
Their previous high was 76 set in 1999.
Improve this graph! Start here:
Consider the SDQL: S2@(team=Blazers) as ‘Blazers Set New First Half Scoring Mark with 84’ and season
Note that grouping by season causes the rendering of a stacked histogram colored by season.
This scatter plot shows the Points vs Opponent Points for college basketball in 2013.
How does this compare with the scoring pattern in the NBA?
The small multiple of scatter plots shows the number of offensive plays vs. points for each NFL team in 2013, sorted by the slope of the least squares fit.
Most teams score more points when they have more offensive plays.
Contrarily, rhe Rams, Bengals, Eagles, Bears and Chiefs scored more when they had fewer plays.
Why is that?
The SDQL used to make this plot is: plays,points@team and (season=2013) as ‘Number of Plays vs PointsnFor each NFL team in 2013’?polyfit=1
This set of small multiples shows the team’s points vs. their opponent’s points for each team in 2013.
The scatter plots are sorted by Pearson Correlation.
The Rams’ final score is most negatively correlated with their opponent’s score: The more points they score the fewer their opponent scores.
The Steelers score was most positively correlated with their opponents: The more their opponents score the more the Steelers score.
This small multiple set of scatter plots shows the points vs opponent points for each NBA team in 2013.
The small multiples are sorted by Pearson Correlation, (shownÂ on the top right),
The Knicks final score is least dependent on what their opponent is doing.
On the other end of the spectrum, the Raptor are happy to score high or low, depending on the opponent.
The motivated viewer sees that the highest scoring game was 145-130, Rockets over Lakers.
The Bulls favor low scoring games, except for two.
The most common margin of victory in 2013 College basketball was 3, followed by 4,5 and 2.
In the NBA the most common margin in 2013 was 7.
Why the difference?
The most common score in Canadian Football is 23 – 20.
Ties are rare and have occurred at 0, 39, 44 and 45.
The highest scoring game was 54 – 51.
This scatter plot shows the team points vs opponent points for all NBA games in 2013.
One sees quickly that the highest scoring game was 145 to 130ish.
The strange brain shaped pattern shows that NBA teams avoid very close scores: in fact a margin of 7 was most common in 2013.
If the teams’ scores were independent we would expect a circle rather than a brain.
I like the gigantic transparent icons because the viewer observers the gray scale directly.
Below is a cleaner version which avoids overlapping icons.
One sees more clearly that there are no ties in the NBA and although, ‘we knew that’, mapping this knowledge to the graphic roots the viewer and gives confidence for further insights.
It seems not inappropriate to spread out these final scores visually – what if that last shot went in ?
What do you think?
The final score (points vs opponent points) for every NFL game 1989 – 2013.
This scatter plot works as a ‘heat map.’
We see quickly that:
- A total of 1 never happens (it is impossible by NFL scoring rules)
- A total of 2 is rare (a safety)
- A total of 4, while possible, has never happened.
- The most common score is around 23, or somewhere in there.
- Ties happen and are rare.
It could probably be improved with a better gradation scheme.
