What are these transformer graphs about?

+1
−1

This picture describes the behaviour of a single phase transform under resistive,inductive and capacitive loads(from left to right)

How what exactly is $V_{1}$ ?Is it the voltage at the primary side?And what are $I^{'}_{2}$ , $I_{1}$ and $I_{0}$? Is $I^{'}_{2}$ the current at the secondary side?If $I^{'}_{2}$ is the current at the secondary side then there is no way $V_{1}$ is the voltage at the primary side because in the first out of the 3 pictures(from left to right) there is a 0 degrees phase difference between $V_{1}$ and $I^{'}_{2}$ and by taking the transformer's equivalent circuit:

and ignoring the branch related to the core of transformer,the transformer itself has a inductive behaviour due to the inductance of the primary and secondary windings so $V_{1}$ cannot be the primary voltage simultaneously with $I^{'}_{2}$ being the secondary current.

So what are the quantities of these graphs?

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.
