The above graph really shows the story of the season. It represents the games over or under .500 the Mets found themselves after each game this season (thus at game 1, they were 1 game above .500). Looking at this graph you really can see the moments of pain and the moments of joy for this season.
You also see how streaky this team is. There are a lot of straight lines, whether they be going up or going down, all over this graph.
The final observation from this graph, it really seems like a roller coaster. It's very interesting to see a visual of the Mets win/loss record because of the story it tells.
