In this second part of the vvvv tutorial on the IOBox (Value Advanced) I will show what the X and Y pins do for the input and output.

We begin with creating a simple slider, than we make it a vertical slider, by changing the slider constraint. When we change the Slider Constrain pin to none, we can change the X and Y value of the IOBox in one go. After this it should become a bit more clear what the Slider Alignment pin does.
