OK, Got my graph. Looks more like an EKG, and I don't mean dead. Having trouble with excel and getting a log scale to only display 10-300. It's stuck on 10-1000. Anyway, I'll try to get it uploaded to my home page and link it back. It was interresting running the test tones and where pockets of sound seemd to "hang out". There were several 2-3 Hz groups of angry hornets in various parts of the room. Also found it interresting to watch the sound level drop on the meter and hear it louder in my ear 3 feet away. I did find a nice way graph, though. I put the sound meter on the back of the couch in the sweet spot and rested my laptop a couple feet away so I could see the display and just entered the spl directly into excel. No copy and regurgitate.
