Why don't you have your workbook do the calculation of intersection point
and plot that as another series.

I have two sets of data plotted on a 2 axis line chart. The data
resembles a cross with one set increasing and the other decreasing. Is
there a simple command that will draw on marker lines showing where
they intersect, with their respective values on the axes?
