Need help with App

Dear EveryCircuit Community,

I am a student in electrical engineering and for one of my labs we had to create this Differential Amplifier circuit (several variations but this is the setup for the common mode gain measurements).

We use B2Spice for our theoretical/ideal models and I forgot to record the AC frequency response plots for these circuits. I have a MacBook and so cannot use B2Spice at my home. I emailed the prof about my problem and told him about this app. He said that if I can create a good model that clearly shows the defining characteristics then I may use the screenshots from it in my lab report.

I was wondering if there is a way to either:
A) alter the y-axis scale for the gain in decibels to more clearly show the corner frequencies
B) remove the phase difference readout (and vice versa with the gain) in hopes of having two separate graphs that look much cleaner

TL;DR how do I do points A and B from above

Thanks in advance

Without frequency sweep, if I understand correctly, several screen "snapshots" at different frequencies would be needed or readings input in graphing calculator to display information clearer?

Bodeplot, but with a proper resistor load and only one parameter to avoid strange scaling in kilo db range. If amp range is still strange not satisfying you can also add some phase to the input source to shift the amplitude graph this is graphical coupled somehow. 606Hz and 3.46MHz are the -3dB corners. Hope that helps.
