I know how to toggle the spray chart on and off by tapping the results of previous at-bats. But what I want to do is turn off the spray chart for all batters from the beginning of the game and never see it again.

I've ended up with unwanted (and invalid) spray charts simply because when I started to use iScore the default was to record hit locations, and it took some time for me to find out how to change that option. At this point, those green lines are just an annoyance.

We do not have a way to turn them off permanently, but we will add the request to our list for future enhancements.

One way you could get around it would be to put the games with hit locations into a league that you keep turned off (the hit charts only show for active leagues).
