Hysteresis

Here's why DC analysis is never enough to explain a circuit. Note how response on raising voltage edge is different from response on descending edge.

I'm not so certain. Every which way I look at this, the waves are virtually identical. Very little if any evidence of hysteresis. Only a slight bump on the rising edge. It is there but hardly. In a hysteresis event I guess I really expect to see much more of a shift between the two traces. I'm not trying to be arbitrary. Maybe I am wrong.

Are you looking at the XY plot ?

Another question. Shouldn't the two compared waves both be the same parameter... voltage to voltage, instead of voltage to current?

To really see it : set voltage source to swing between 0 and 2V (instead of -2V to 2V) and look at X-Y plot.

@UncleRick: I'm not a specialist, but I don't think the two parameter have to have the same Unit. As long as the behavior of the system is not symmetrical when time is reversed, you have hysteresis. Also : if you want, you can look at voltage drop in resistor after voltage source. It should behave like intensity thru it and you have what you wanted.

@UncleRick : look at Hysteresis V2. Should do what you want.

I did do that. Ya got me.
