analog stick coordinate reporting

[Batcastle]

So this entire issue is just trying to figure out how the coordinates for the analog sticks are reported. More specificity, what is the coordinate system? For instance, is the X- and Y-axis like this:

Y
|
|
|                 * - default orientation
|    origin
|  / 
------------------------------------- X

or are they like this:

                Y
                |   origin AND default orientation
                | / 
----------------*-------------------  X
                |
                |

also, knowing how far the X and Y axis go would be useful too. That way, a dev can convert from one of the above graphs to another with just some simple subtraction to both X and Y coordinates.

So, in a nutshell:

1. What quadrants of the coordinate plane does this work with? Just one? Or all 4?
2. How far do both axis go?

1) For my XBox controller it dose go into the negatives, so origin and default are 0, 0 2) Im trying to figure this one out my self, I've seen for my XBox controller that it ranges between -32768 to 32767 With both of what I said, I think this may vary for each type of controller?
