AnnotationSmith
AnnotationSmith allow displaying mouse-interactive text labels or graphics anywhere in the chart area. ViewSmith.Annotations are similar to ViewXY’s Annotations (see AnnotationXY) with the exception of Target and Location being defined in smith axis values (real and imaginary). Sizing by axis values is not suitable and therefore Sizing property has only values Automatic and ScreenCoordinates.
