FFT graphs in Mission Planner and MAVExplorer

[Allister (Allister Schreiber)]

I’ve been messing around with graphing in MAVExplorer and trying to follow along with some of the discussions here on different tuning issues. I’ve just noticed that when I use the FFT tool in MAVExplorer the gyro graphs don’t seem to display the same data as the FFT graphs in MP.

These two graphs are from the same log file but the amplitudes are different, and the peaks are on different axis.

What am I missing?

The X,Y, Z axis assignments is a clear bug in at least one of the softwares

I’m going to assume that the error is in Mavexplorer, given that using MP to set up filtering is the standard. Is this bug known?

Nope, not know AFAIK. Please report it
