It's the elevation angle (from the horizontal).

The reason you don't see the graph appear to visually correspond to the launch angle is because the X and Y axes are not scaled equally, and when you change the launch angle the scaling auto-adjusts to fit the graph.

While you're here, does your team happen to have any test data to confirm (or refute) the 37 ft/sec terminal velocity number for this year's game piece?
