Are you wanting something different to the IMAQ Overlay VIs? With a combination of Overlay Text and Overlay Line I would think you can achieve much the same result as Annotations.
Or are you asking for the ability to define an Overlay from the right-click-menu? What would be the need for doing that?
Greg - Open a new blank VI. Drop an intensity graph on it. Press the continuous run button on the VI. Right-click on the graph. Note the 'Create Annotation' option. That is what I mean. I am currently some annotations using overlays. Right-click option would be nice.
