The surface chart in Excel is a category chart and would be of
no use to you.
Sigma Plot and others provide stand-alone and/or Excel add-in

Hi,

I have a need to plot a line that has x,y,z co-ordinates
(i.e., E/W of origin, N/S of origin and depth below origin).


I don't want to be supercilious but the OP might want to review
elementary Cartesian geometry especially the equations of surfaces and
lines in 3D.
