RACE CONTROL PANEL
The Legend is dynamically set to display all the competitors in a race. If there are scratchings in a particular race, these names are shown with a strike-through and the corresponding functions are disabled. The coloured check-box indicates the competitor-colour used as reference in other parts of the application. Click on this to highlight the path taken by the horse in question, and click again to remove. Multiple selections can be displayed to compare various aspects of the race.
The plain check box is used to make selections for the popup charts. When no box is checked, all graphical points are plotted. Again, this could be useful for comparing performances between two or more competitors. A click anywhere on a particular line will enable or disable the name tag that is attached in the main panel and the zoom-panel.
The five buttons beneath the Legend are used to control the race playback, much the same way as controls on a video recorder. Functions are provided to Play, Pause, Stop, Step-Forward, Step-Back, and Fast-Forward. If the race-call audio is enabled, the sound will synchronize and play as expected from any point in the race.
