Robot Characterization Help

Hi all!
We have been working on autonomous for our robot this year and we’re hoping to use PathWeaver. However, in order to use PathWeaver we need to set up trajectories & in order to do trajectories we need to run the Robot Characterization.

We are using a differential-drive base with Neos and SparkMAXs with the built in encoders. For our gyroscope we have the NavX2.
As shown below, our graphs don’t seem to be quite right and they also don’t match anything on the WPILib troubleshooting guide. We’re somehow missing part of both the Dynamic Acceleration & Dynamic Velocity graphs. Any ideas on how this could happen??

I don’t really know what we’re doing wrong, any suggestions would be awesome!!

I have no idea, except to say your data looks a lot like theirs:
