One of the great, hidden features of Logger Pro is the ability to add vector displays to motion you are studying. Two sample files that use this feature are included with Logger Pro. One of the files, “Basketball Shot vector analysis,” can be found in the “Sample Movies” folder. If you open the file and play the movie, the vectors appear on the movie as the ball moves.
For a tutorial on how to set up animated displays in your Logger Pro files, choose Open from the File menu and navigate to the “Exploring Animated Displays” file in Sample Data > Physics > Animated Display Vectors.
