Two years ago Mike P. from KC asked:
"Is it possible to have a data cell's comment (which shows up on mouse-over
of
the red triangle in the upper right of the cell) also show up on mouse-over
of the data point on a chart that takes a data point or points from a
"commented on" cell(s)? If so, how can you do it? "

The only reply was from Jon Peltier: "This isn't a native Excel capability,
but it's an interesting idea, and one that could be accomplished using VBA."

Does anyone know if this has been done yet? If so how could I get that macro?
