Preferences

A number of preferences can be set by the user. *''Visible Shots'': The number of shots visible at one time in a certain point can be set to either 1, 2, 3 or all. *''Speed Display'': The speed display can be set in mph or km/h. *''Track Display'': The line of the ball in a point can be displayed as a solid line or a ball. If a line is chosen, then a green line (Wimbledon and Roland-Garros)/orange line (Australian Open) (showing the path of the ball hit by one player) and a yellow line (showing the path of the ball hit by the other player) is displayed. The number of lines displayed at one time is dependent on the setting chosen in ''visible shots''. If a ball is chosen, then the path of the ball is shown by a yellow tennis ball and the setting chosen in ''visible shots'' is not applicable.
