Positioning question (drawing a simple circle)

This may be a ridiculous simple question, but I can't figure this one out...

I tried drawing a circle using the following function:

drawCircle(x, y, radius)

Where x and y are according to the documentation of Pixi:

Quote

The X/Y coordinate of the center of the circle

If I want to change the position later, I can use the: circle.position.x or circle.position.y method. If I set both at (2,2) (position.x = 2 and position.y = 2), I see that the position is different than the one I used to create the circle with: drawCircle(2,2,1).

I then don't understand the API's ''the x,y coordinate of the center of the circle''.. Wouldn't that be the initial position of that circle anyway?

The thing is, what you pass in drawCircle is not a position, its coordinates of the circle relative to the graphics you are creating. So you have to use "graphics.drawCircle(0, 0, 1); graphics.position.set(1,1);"

To understand why API works that way, imagine that graphics has two circles in it. Which of two circles position will appear in "graphics.position"?

Thank you Ivan!
