Peak Integration
– This option calculates the integral for a selected portion of a
graph. It is most commonly used with the Vernier Mini GC, but it can be applied
to any data plot. Peak Integration differs from the Integral tool in that it does not
use the x-axis as the baseline. Instead, the integral for Peak Integration is
evaluated from the minimum y-values to the left and right of a selected peak.

Draw Prediction
– The Draw Prediction tool
gives you a free-hand sketch tool for drawing on
the Graph screen. This can be used for a variety
of purposes, but is most often used to sketch a
prediction of how a graph will appear once data
are subsequently collected.
Upon enabling this tool, tap-and-drag across the
screen for smooth curves, or tap the screen to
connect subsequent taps with straight-line segments. The Reset button will remove your
sketch if you need to start over. Tap OK to place your sketch on the main graph. To
remove a prediction, choose Draw Prediction again from the Analyze menu.

Motion Match
– The Motion Match menu item is
only available if a Motion Detector is connected.
You have a choice of a new Position or Velocity
match. In each case LabQuest generates a
random target graph for matching exercises.
Only the selected graph, Position or Velocity, is
shown in match mode. You may collect data
over the target graph as many times as you like.
To see a new target graph, choose New Position
Match or New Velocity Match again. Remove
