In this joystick, the x-axis and the y-axis have their own potentiometer. Together, they build a voltage devider like the one in the next picture.

If one of the axis changes, like the x-axis for example, the values of the resistors will change - e.g. value of resistor 1 will raise than the value of resistor 2 will fall or the value of resistor 1 will fall and the value of resistor 2 will raise. According to the division of the resistor values, you can measure a specific voltage value between the resistors and locate the position of the axis.
