I have a conflict with dispersion ellipse it is on XZ-plane or XY-plane?

First of all, I just recently play this for my daily games, so there are some mechanics of the game that I don't really understand.

English is not my first language so please be lenient with me...

Here is my problem, one of the community member give me this image about dispersion ellipse:

So that our perception is same, let we use this image which I stole from google:

Let's say that from BOW to AFT it is on X-axisand from base to superstructure is Z-axis while width of the ship is y-axis.

Let's say I am shooting from somewhere on point (0, y, 0)

Does the image of dispersion ellipse is the elipse on XY-plane or XZ-plane?

Typo should be XY or XZ

I'm really not good a maths and algebra and all that anymore so let me explain it simply for you.

On the ellipses, L to R is the enemy ships length, if broadside or side on to you.

Top to bottom of the ellipse is starboard to port or the inverse (so width of the ship).

The ellipse is from a birds-eye view.

So you are saying it is on the XY-plane or just say, the dispersion of bullet when falling on the water, right?

Yep, if I understand you correctly...

It's a view from the sky, directly above.

The game itself uses XZ for ship position and hit position. I've checked a replay's data. This is just a small dump:
 

{'paramsID': 4259300176, 'ownerID': 1088056, 'salvoID': 4, 'shots': [{'pos': (-400.0229797363281, 0.4155093729496002, 217.19813537597656), 'pitch': 0.15145014226436615, 'speed': 780.0, 'tarPos': (-584.5059814453125, -0.05749824643135071, -183.65017700195312), 'shotID': 9, 'gunBarrelID': 4, 'serverTimeLeft': 22.185009002685547, 'shooterHeight': 0.0, 'hitDistance': 440.5024108886719}

As you can see "shots" 's "pos" & "tarPos" uses XYZ, and the only big numbers are XZ therefore XZ I think.

The game works out all sorts of things...

The diagram actually says that yellow is Iowas length and beam (length and width, not height) the dispersion ellipse he's asking about is 100% flat on XY.

OP, stick with what I wrote, don't get confused.

If you want the nuts and bolts, the game has 'horizontal' dispersion, on plane x and 'vertical' dispersion (that isn't vertical at all) on plane y.

It can then interact with things on the way to that target on x, y and z axis.

Dispersion mentioned in-game is measuring horizontal or x.

Don't overthink it, just learn how to aim.

Only thing you need to know about anything is some ship lines have different shaped ellipses, as the diagram shows.

Different ship classes have different formulas, different ship lines in each clas sometimes have different formulas, each ship has values defined unto itself. Good values in any one area don't mean anything. Good values in a range of areas change the dispersion ellipse and how many shells land within it.

If you want to get into it further, look up iChasegaming on Youtube, he's probably the best at explaining it. But that's in english, goodluck.

Edit: sorry if it's a bit blunt I'm tired and need sleep, not angry or trying to be insulting, just tired.

If you want good shots, play the russian BBs, their "ellipse dispersion" is the narrowest.

USN BB are plain frustrating, same with ze germans.

RN BB i don't play, but they say they have great accuracy.
