  <p>I want to implement the functionality where user can pick height and weight by scrolling the pointer over the ruler. Basically I need to set the upper and lower bound of ruler to avoid over scrolling. And the value of movement of pointer should be displayed. So give me some idea to implement this feature.</p>
