Hi! When I select Freq vs Throttle I dont get a spectrograph. It does show up under Freq vs RPM. Any help here is appreciated. Thank you!

not enough data to create all graphs.

@tired roost thanks! does this mean to record for longer? Im using O4 Air unit I was reading that possibly there is something I could need to disable related to gyroflow in that?

yes, longer, maybe more input. (RPY, Thr)

This is a Pavo Femto for anybody else that encounters the same issue.

@plucky tinsel I don't think you need to record for longer. You need to make sure the necessary fields are being logged. In Betaflight, in your blackbox tab, you need to enable PIDs, Gyro filtered, Gyro unfiltered, RPM, and Setpoint. Optionally you could also log RC Commands, Acelerometer, and Motors. The rest are unnecessary and can be disabled, unless you know you need them.

#

Crucially though, you need to enable Setpoint. That's the disabled field that is preventing you from seeing Freq vs Throttle.
