Firstly, this example comes from Ethan Winer at Real Traps. In this example, a small room was treated extensively in a non-obtrusive style.You can see it in his Hearing is believing video.
Now here is my own result with some thrown together temporary bass traps.
The improvement is much more than you would expect from this chart. It was a big improvement in tightness and bass control. I have heard many high end systems and the bass I'm getting here is equal to the best I've heard.
How to read these charts
The most important charts shown are the waterfalls. They are simply a frequency response that is measured over time. At the top of the chart you see the response that would normally be measured. Then follow the response as it changes in time, moving down the Z direction as you would if going down a slide.
What would a perfect waterfall look like? You would see at the top a completely flat line with no peaks or dips. You would then see a uniform slope across the entire range that slides down quickly.
You can best identify room modes by noting peaks that decay slower than what you see either side. They become sharper over time because of that slower decay. You can see this illustrated here:
