Very briefly, while looking at the Heat Map vs Swing % article on FanGraphs, I thought of a graphical representation that could tie the Heat Map and the Swing % together. It would be a 3-dimensional bar-graph (essentially) where the heat map faces the viewer as a flat edge, and the swing percentages are represented by bars extending "backwards", away from the viewer. One problem is that the whole graph would have to be tilted at a slight angle so the swing % bars could be visible - not sure how difficult that would be to produce. link to article http://www.fangraphs.com/blogs/index.php/comparing-plate-discipline-visually-and-numerically/#more-34600
