Where did you find these diagrams? There is probably some explanatory text around them.

Hmm there isnt a explanatory text around them ,the diagrams come from the slides of my college professor and he just showed us the diagrams without explaining what the quantities on the diagrams are.I am interested in knowing what they are.

He probably used the same naming convention in his slides as in whatever book was assigned for the class. There are probably similar diagrams in the book, which should include better explanations for what the variables and axes mean.

I can't tell whether these are supposed to be diagrams in a single plane, or attempts to show three dimensions. I also don't understand the multiple labels for the single vertical axis. It looks like trying to figure out what these diagrams are supposed to tell you will be rather time consuming without the proper decoder ring.
