You can use the GetX method from the Joystick class to return a float of the joystick from -1.0 to 1.0:

If you lean over half way to the left (on the x axis) it turns the relay reverse. The opposite then for the right direction and then off for in the middle.

if(thirdStick->GetX() < -0.5) // IF OVER HALF WAY LEANING TO THE LEFT
     agitator->Set(Relay::kReverse);
else if(thirdStick->GetX() > 0.5) // OVER HALF WAY TO THE RIGHT
     agitator->Set(Relay::kForward);
else // NEITHER/IN BETWEEN
     agitator->Set(Relay::kOff);
