Default colors for data shown in the graphs allow those who are color blind to easily distinguish the different colors. To
change the colors used for each type of data, click the
Graph Colors
window tab in the
Options
window. Refer to the
Reference Manual.
The default layout places the right graph (right head and eye velocity data) on the right and the left graph (left head and
eye velocity data) on the left. To switch the layout, click the
Head Impulse
window tab in the
Options
window and select
Display Left Graph on Right Side
. Refer to the Reference Manual.
To view only the head or eye velocity, click the
Display
window tab and click the
Head Velocity
or
Eye Velocity
check
box. To view both head and eye velocities, select both check boxes.
Head data is shown in blue for left and orange for right. Eye data shown in green identifies eye movement during and after
the head impulse (VOR). Eye data shown in red identifies saccadic eye movement (in other words, the catch-up saccades).
Data is shown with velocity plotted on the Y axis and impulse milliseconds or samples along the X axis. For data that was
converted from an earlier version of software, the X axis will display in samples if the average frame rate was below 219.
