Display X-Axis value in Descending order?

In Silverlight toolkit chart 开发者_如何学编程control, the X-Axis value is displayed by default in ascending order. How do I make display in descending order?

Thanks...

I posted it on silverlight forums. This is how we do it:

<charts:CategoryAxis Title="x-Label" Orientation="X" SortOrder="Descending"/>

Thanks...
