spectroscope~ that is labeled with the grid of frequencies

Hello everyone.

I'm feeling a bit dim here so please forgive me, but I can't seem to find something like a [spectroscope~] object that actually has the frequencies labeled along the bottom. As it is, the [spectroscope~] just shows you a bunch of sounds are happening at certain frequencies but there is no way to tell roughly what they are.

I know I've seen something like this before but I can't remember where. It's driving me a little nutty so I thought I'd ask the forum here.

Any advice is kindly appreciated.

Thank you.
