New Post: Formatting the Tracker control

Hi idmm,

I realize this is 2 years late, and that your problem is solved for you by now. But I myself recently needed to do exactly this, and found your thread together with everytimer's extremely rude and unhelpful response. So I will provide my own solution for others to find.

In your window resource set the following style:

<Style TargetType="oxy:TrackerControl">
            <Setter Property="Background" Value="White"/>
</Style>

(Caveat: This may or may not work in non-wpf versions of oxyplot.)
