this option off turns the area under the measured data black in the plot.
• Draw Plot Coordinates Only When Ctrl Key is Pressed - Display the cursor's plot coordinates
only when the Control key is pressed. The plot coordinates are the elapsed time of the trip and the
data value associated with that time. If not checked, the cursor's coordinates on the plot are
displayed continuously when the cursor is within the plot area.

Normalize vertical axes to ___ MPH / KPH - Set the upper limit of the vehicle speed plot to the
speed of your choice. You can change the speed used to normalize the axes by highlighting the

limit of the vertical axes will be the maximum speed achieved by the vehicle during the current trip.
