Automatic Inclusion of Comments on Chart Data Points??

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?

I would like to be able to see comments when I mouse-over a data point on a
chart if the data point was taken from a cell with a comment.
