How do I get the trigger pressure from gamepad?

I read the GamePad doc:

construct.net/en

RawButton(Gamepad, Index) Retrieve raw button input for a specific gamepad and button index. This returns the value without keymapping. Button values range from 0 to 1 (pressure sensitive buttons can return values in between).

I'm using a Xbox One controller. I figured the triggers are 6 and 7 so:

Gamepad.RawButton(0, 6)

Gamepad.RawButton(0, 7)

But it not retrives anything between 0-1. Just 0 and when the trigger is around 50% then changes to 1.

So how i get the pressure of triggers correctly?

Well, is fixed, just the textobjects was small for all the float values so only when was 0 or 1 it fits the visible zone.

Btw, it gets to 1 before press at 100% but i guess is due some deadzone, will see.
