Display X and Y axis details

[stpr-dev]

Hello there!

Your app is a life saver for me, without it I couldn't be sleeping as well as I am these days! :)

I just wanted to request you to include the details of X and Y axis (is this similar to #5?).

• Is the 'amplitude' linear or logarithmic? Relative amplitude step information?
• Is the 'frequency' axis linear or logarithmic? What is the start, end and step size of the frequency axis?

Would it be possible to set these values (perhaps in the settings)? Would also be nice if both linear and log scales were available. Being a signal processing graduate, these are interesting to know. Let me know what you think!

Sounds like 'a piece of cake', but it would alienate the general audience to the app's main purpose.
