How can I change it? Which style is responsible?

Hello Kristoffer,

 You can change the Thickness, Stroke and StrokeDashArray of these lines by setting the following set properties:

xmlns:primitives="clr-namespace:Telerik.Windows.Controls.Diagrams.Primitives;assembly=Telerik.Windows.Controls.Diagrams"

<telerik:RadDiagram x:Name="diagram" Margin="30"
                          primitives:AlignmentAdorner.VerticalLineStroke="Aqua"
                          primitives:AlignmentAdorner.HorizontalLineStroke="Aqua"

                          primitives:AlignmentAdorner.HorizontalLineStrokeDashArray="1 2 3"
                          primitives:AlignmentAdorner.VerticalLineStrokeDashArray="1 2 3"

                          primitives:AlignmentAdorner.VerticalLineStrokeThickness="3"
                          primitives:AlignmentAdorner.HorizontalLineStrokeThickness="3"
                          >
          <telerik:RadDiagramShape />
      </telerik:RadDiagram>

We hope this will help you proceed further.
