I have multiple 2D contour plots that I'd like to plot in one 3D figure one on top of the other with some distance in between each of the plots. How to do this?

You can achieve this by modifying the 'ContourZLevel' property of the contour plots. For example, the following plots two contour plots with some distance between them in the Z-direction:

[X,Y,Z] = peaks;
hold on
[~,h] = contour(X,Y,Z,20);   % plot contour at the bottom
h.ContourZLevel = -9;
[~,h] = contour(X,Y,Z,20);   % plot contour at the top
h.ContourZLevel = +9;
hold off
