In the subject you mention a vertical ND curve but in the body you=20
mention horizontally. So, it is not clear what you want to do.

In any case, you might want to check http://www.tushar-
mehta.com/excel/tips/index.html specifically the link for 'Invert and=20
rotate charts'

To draw straight lines that match up with pre-determined values see=20

Also, Jon Peltier has an alternative approach on his site.

In article ,=20

I would like to plot a normal distribution curve horizontally (on the Y a=

in a chart with vertical data histogram plots (up and down) and horizonta=
l=20
line plots (+/- 1 SD) =E2=A4=3D3F all currently using the Y axis. I have=
the=20
histogram/SD portion built. Is there a way to use a secondary axis on th=
e=20
left side of the chart for the nd curve, yet have the nd curve appear on =
the=20
right side of the chart? Actually, it may not make a difference just whi=
ch=20
axis, Y or secondary, the plots are attached to so long as the plots can =
be=20
placed on the chart in an orderly fashion to display three issues: histog=
ram=20
data, lines for +/- 1 SD, nd curve - the SD lines must be logical with th=
e nd=20
curve. The next question: how would I shade the area of +/- 1 SD?
