andengine - Rotation angle based on touch move

I want to rotate my stick based on the movement of the touch on the screen. From my calculation I did not able to find correct angle in degree. So please provide guidance, my code snippet for that are below.

if (pSceneTouchEvent.isActionMove()) {
    pValueX = pSceneTouchEvent.getX();
    pValueY = CAMERA_HEIGHT - pSceneTouchEvent.getY();
    rotationAngle = (float) Math.atan2(pValueX, pValueY);

    stick.setRotation((float) MathUtils.radToDeg(rotationAngle));

}

Answer

The answer for the above question is as below

    if (pSceneTouchEvent.isActionMove()) {

        pValueX = pSceneTouchEvent.getX();
        pValueY = CAMERA_HEIGHT - pSceneTouchEvent.getY();


        directionX = pValueX - stick.getX();
        directionY = (CAMERA_HEIGHT - pValueY) - stick.getY();

        rotationAngle = (float) Math.atan2(directionY, directionX);

        stick.setRotation(MathUtils.radToDeg(rotationAngle));

    }
