How to plot 2D graphs (no function) over time into 3D?

Hello,

I look for a way to plot 2D graphs (x,y) over time (z) into 3D structure. My problem is, that the 2D graph is not a function, so it's plotted by 100 values of x and y for each z value.

I tried several ways, for example the plot3() function including a loop, but then the vectors don't have the same length. And using surf() demands a function for z, but I have just a vector.

Thank you for your support, Dominik

surf() never wants a function: surf works on a rectangular data array.

all_z = [z1(:), z2(:), z3(:)];
surf(x, y, all_z)
