View the tracks in multi-arena setups

In trials with multiple arenas, all tracks are played back starting from the first sample. If the tracks started at different times in different arenas, the samples visualized at a given time refer to different 'real times' in those arenas.

To preserve the time difference between arenas, choose Integrated Visualization.

Below: In a multi-arena setup, data recording may start at different times in different arenas. When tracks are plotted together, their starting times are aligned. This means that samples visualized simultaneously for the two arenas may refer to two different moments in the real time line.
