Maybe ibam ? AUR (en) - ibam
Info here: https://ibam.sourceforge.net/
You might be able to -plot it the way you want.
Sorry that I can not test it for you as I do not have a laptop.
To install it open up Konsole and type:
paru -S ibam
enter "Y" to review. Then hit "Q" to exit the review. Then "Y" to install.
After it is installed you should be able to look at a simple graph with typing ibam -plot into Konsole. Additional commands can be seen by looking at the help for ibam from putting ibam -h into Konsole.
