Need help! Cannot graph FFT analysis from log file for notch filtering analysis

Hello Everyone,

I want to enable Dynamic notch filtering for my quadcopter with ESC telemetry, but when I followed this guide to graph FFT analysis, nothing is graphed in the fftui window:
https://ardupilot.org/copter/docs/common-imu-notch-filtering.html#flight-and-post-flight-analysis

My log file is here: https://drive.google.com/file/d/1jaeFAcuJ2CqoJvhGokYqGHPL9y4KR2Sw/view?usp=sharing

Could someone suggest if I was missing something? I appreciate any feedback.Thank you!

You are likely missing the batch logging options. In particular is INS_LOG_BAT_MASK set?

Thank you very much! Yes currently INS_LOG_BAT_MASK = 0 so it should be the reason. I will change it to 1 and try again!
