I believe it’s called a “joint probability density function”.

Quite clever, actually. I had not thought to present data that way, although I was aware of it. Tom Sosnoff’s theta-copping 45-DTE undefined risk strategies take advantage of that overwhelmingly large occurrences blob in the middle. 8/7/19

Maybe a little closer conceptually ... .

Try it again ...

I’m actually studying 2-inch-tick tomes trying to reach myself how to read that chicken-scratch. 8/7/19

I’ve had great difficulty getting these links to work. Don’t know why. I can’t seem tom fix it at my end, either. 
 
Wikipedia does a half-way decent job of explaining what a Joint Probability Density/Mass Function is.
