How to change order of drop lines relative to the plotted data inExcel 2007 chart

[icystorm]

What is the procedure for changing the order of drop lines relative to
the plotted data in an Excel 2007 chart?

I would like the chart;s drop lines to remain active, but appear "sent
to the back" behind the plotted data.

I attempted to help myself by searching extensively, but I was unable
to find the solution.

I think it may require a VBA entry, but, if so, I will require
assistance.

Are the references below pointing me in the right direction?
