I am looking a way to highlight segments (in yellow) on a slider/progress bar

I am looking a way to highlight segments (in yellow) on a slider/progress bar like this:

slider with highlighted segments example

I found some article discuss how to build customized WPF slider control by using style:

But what I need is to highlight given segments on the slider bar programmatically.

For example:

//Given:

List<Rectangle> rectangles; 

//And invoke

mycontrol.highlight(rectangles);

How could I do this? Or more specifically, how could I draw on the slider bar at runtime?

    in slider
    Property IsSelectionRangeEnabled

    If true, you can use a selection range to shade in a portion of the
    slider bar. You set the position selection range using the
    SelectionStart and SelectionEnd properties. The selection range
    has no intrinsic meaning, but you can use it for whatever purpose
    makes sense. For example, media players sometimes use a shaded
    background bar to indicate the download progress for a media file.
