I presume you mean you're plotting the second series as an XY series with
lines and no markers. If you plot it on the secondary axis, the lines will
appear in front of the markers on the primary axis. If you plot the second
series as a line series rather than XY, its line will be behind any markers
of an XY series.

I have a scatter plot with thousands of points (markers only, no line), and
am plotting a second series as a line with only a few hundred points over
the
same range of x-values (line only, no markers). I want the line to appear
in
front, but Excel 2007 keeps putting the marker symbols in front, which
completely obscures the line.

I have tried changing the series order, but it makes no difference. In
the
Chart Tools - Format - Arrange toolbar, there are "Bring to Front" and
"Send
to back" buttons, but they are greyed out.

Suggestions?
