You often see spray charts for batters showing pull and opposite field tendencies, but what about elevation? A vertical spray chart could show some interesting information about things like loft and groundball tendencies. Unfortunately, without HitFX, there's no accurate way of getting launch angle data, but as a proxy for that, we have groundball and flyball data. In this visualization, the angle of each line represents a ratio of groundballs and flyballs, where a batter that only hit groundballs would be represented by a horizontal line, and a pure flyball hitter would get a vertical line. Additionally, the magnitude of each line corresponds to season wOBA. I used data from all of Oakland's batters in 2010 with at least 100 plate appearances. And, as always, click for a bigger version.
