I have got a CustomTextAnnotation like in this example CustomTextAnnotation
I added a Rendertransform like this.
<s:TextAnnotation.RenderTransform> <RotateTransform Angle="90"/> </s:TextAnnotation.RenderTransform>
But the AnchorPoint is not used as rotation center.
I thought of using ToCoordinate() but need a calculator for that which is not available within CustomTextAnnotation.
What is best practice to achive the requested rotation in sciChart?
