Just did some tuning on a new build. Did the filter tuning using MavExplorer. The gyro graph on the left makes me think I nailed it. Then for reasons I plotted the same log in Mission Planner (latest beta within the last 18 hours). Now I see another bump, and the scale is negative.
I’ve checked this log on 3 different installs of MP (all latest beta), and both of the windows installs gave me a graph like the one I posted. The linux install was okay. Is log scaling something I’ve accidentally turned on or what am I overlooking?
The small “magnitude” checkbox on the FFT screen, lower left. Check it before loading the file. Personally I don’t think log scaling is that useful for the purpose we are using it for here.
