I am plotting vectors that are equal to the change in angle of a persons arm from motion capture data!
My main problems arise from the start and stop times of the data collected. (For example one person starts at 2 seconds, the next trial starts at 2.5 seconds, but the general lengths from start to end of a motion are the same)
The image posted below is an example of 2 of these trials plotted on top of one another. What I would like to do is allign them so that the starting point (where the rate of change begins to increase) so that I can more meaningfully compare them visually.
