Can I still view WIFI performance

I liked the way we could view the connectivity strength and noise level in the wifi performance window in Lion. Can't seem to find where I can see a similar chart in Mountain Lion.

Anyone else have a clue?

Thanks for quick reply. That is helpful/Good-to-know info!

But what I was really looking for is the chart we used to be able to see that looked like this:



It was found in the WIFI diagnostics area in Lion. I was helpful for me when troubleshooting some router issues in the past and was hoping to use it again today.... no luck finding it tho.
