Deciding on a proper graphing calculator window?

[Tyrion101]

I'm struggling with this lately, I know that it depends on what you need to see, but is there a general rule of thumb?

Make it big enough so you can see what you need to see, but not so big that you can't see what you need to see.

But is there a way to tell without randomly picking numbers for a bit to tell how big your window needs to be?

I'm not aware of any general rule about this. How you should scale the window depends on the function you're graphing.

Not really. I mean it takes 15 seconds to figure it out by guessing, I never really needed to save that much time.
