'stacking' 2D graphs on top of each other.

I have multiple 2D graphs (but of different lengths/sizes). I want to stack them together to form a 3D image (not necessarily a surface). Stacking them on top of each other is fine without the surface. Please help me make this kind of graph.

There are plot3, contour3 versions of plot, contour for which you would have to add a third coordinate for each 2D plot, if that is what you are trying to do. For instance

plot(x1, y1)
plot(x2, y2)
plot3(x1, y1, repmat(z1, size(x1)))
hold on
plot3(x2, y2, repmat(z2, size(x2)))
