I will suggest picture control over graph, or customized slider.

I am quite new to these 2 fields, may you give any detail suggestions.

Thanks.

Very quick and dirty implementation in attachment. Uses it as starting point.

With Picture control you may get more flexibility, but need more programming (muse Enter/Leave/Move, etc)

With Slider - a little bit more easy (I will recommend this way for you)
