Where to get item styles for StackedSplineArea and StepAreaSeries?
===

I am creating an app with teleriks silverlight controls.   
I had a problem with chart coloring. It is adding some opacity and gradients to charts.  
It can be fixed by changing item style from SeriesDefinition.   
For Bar charts I found template by googling and changed it as needed, but I can't find templates for  StackedSplineArea and StepAreaSeries.   
Where can I find this templates?   
I tried with blend, but it does not give any template.   
Thanks
