Jon, thanks!

Your example answered my question brilliantly. After some translation from
your VBA to my Managed C++, I have what I need.

Thanks again.

The code is not so complicated that you couldn't see how to draw your

I'd like to be able to determine the location of a data point relative to the
chart object. My goal is to automate the drawing of a horizontal arrow
between 2 series that form vertical lines on an XY scatter plot (similar to
the dimension lines on an engineering drawing). Is this possible?
