The typical screen shown above is for a Velocity vs. Time graph with only the positive y-axis displayed. The
measurement parameter
indicates the starting date and time of the graphed data. Notice that most of the locator bar has been replaced by a status
line in standard video that shows the value, units and time of the measurement at the current cursor location. However,
there is an inverse video pointer at the far right of this line to indicate that additional option bar choices are available.
Note: The date in the message line includes only the day and the month (not the year), and the times in the status line
and the message line include only the hours and minutes (not the seconds).
