Drawing Predictions
The LabQuest App has a free-hand sketch tool for drawing on the Graph screen. This can be
used for a variety of purposes. It is most often used to sketch a prediction of how a graph will
appear once data are subsequently collected.
Choose Draw Prediction from the Analyze menu.
Select the desired graph (Graph 1 or Graph 2) to
activate the tool.
Touch-and-drag across the screen for smooth curves
or tap the screen in several places to connect
sequential taps with straight-line segments. The Reset
button removes 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.
TIP! When collecting data, the data plot over the
prediction line.
