Not being very lucky with the Copy Data method of graphs lately.
Take the following graph (from the attached VI):
and try to copy its image data to paste it into some other software (Word, Powerpoint, Paint, Preview, whatever) by invoking Data Operation >> Copy Data.
I get this:
An annotation with an arrow goes haywire and one without simply disappears (no anchoring point displayed).
Tested in LabVIEW 2016 64 bits, Windows 7.

CAR 640243 was filed for that bug, which has some other variants.
For instance an annotation in a XY graph needs to be associated with a plot, or it won't be displayed in the image generated by "Copy Data".
If associated with a plot (which is not possible in my case, but could be a workaround in some cases), it cannot be positioned using the XY coordinates, but only the plot element index...

According to the CAR there's a workaround of using a Waveform graph which will copy the annotations correctly or using a "get image" invoke node (Picture on attached vi) to display an image of the graph that copies properly.
Would that work for your application?

Sure, the functionality can be emulated. However, the purpose of the post was not to look for a workaround but bring the attention of NI on the bug. Mission accomplished, over and out. Anyone willing to discuss workaround is most welcome.
