Origin Ver. and Service Release (Select Help-->About Origin): OriginPro 8.5.1 SR2
Operating System: W7
Hi!
I'm trying to make a plot, not unlike the example I cobbled together in PPT so I wouldn't have to explain it in words - that IS what graphs are for, after all.
I'd really like to do it in Origin so everything lines up nicely and I can express a 4th dimension on the Z-axis defining why the layers are different. Is this possible? If yes is it straight forward?
Thanks again!

Hi luser,
There is no straightforward way to make such stack contours in a 3D-space. One work-around is
to make individual contours as the XY-plane projections of 3D surface plots, then to merge them
as layers into one graph. Here is the procedure:
1) Make 3D surface plots from your data, and let them have the common XY scales and the rotational
angles. Hide the surface and show the bottom contour from the "Surface/Projections" tab in the
plot-level Plot Details dialog.
2) For each graph, open the layer-level Plot Details dialog, choose Miscellaneous tab, and choose
"Orthographic" projection (not to make gaps after merging).
3) Hide all unnecessary axis elements from Plot Details dialog box ("Plane" tab and "Display" tab),
and from Axis dialog box ("Grids" tab, "Tick Labels" tab, and "Title&Format" tab).
4) Merge all graphs into 1x1 arrangement. ("Graph:Merge Graph Windows" menu)
5) In the Plot Details dialog (layer-level), select "Size/Speed" tab, and change the "Top" position
of each layer so that each layer shifts vertically. (negative values for child layers at "% of Linked layer").
Hope this helps.

Thanks Hideo Fujii for taking the time to figure that out.
It will work, but isn't ideal because the z-axis isn't the 4th dimension, but the 3rd repeated. So the z-axis will need to be hidden and the 4th dimension added as simple text.
I should stop doing things that no-one else does.

This is not the problem. You can just turn the Z axis of layer1, if I understood correctly.

I don't understand what you said here.

No, no, not few people asked us such stacked contours; so what you envisioned is not what no-one else does.
We are planning to release a new version, 9.0 sometime in this year, and in this new version, arranging contour as stacked could be done easier as the contours can be arranged within a single layer.
I think you would like this nice 3D features.
