Custom values on trackbar (Slider) windows form

I am trying to implement a trackbar control that gets its values dynamically , I cant see a way to link it to a datasource.

For example , If I have my values as
Private trackFactor() As Double = {0.25, 0.33, 0.5, 0.66, 0.8, 1, 1.25, 1.5, 2.0, 2.5, 3.0}

How do I set this on my trackbar control?

Thanks
