[Scilab-users] Stacked 2D plot in 3D

[Claus Futtrup]

Dear Scilabers

I am trying to make a kind-of 3D plot, but with lines (in 2D). Attached a
file that shows what I wish to do.

Below some code that shows current state, but given the desired result
(attached), I'm not happy with it. I'm "cheating" a bit to make plot3d
accept my input data and I Wonder if I'm on the wrong track?

Best regards,
Claus

    // above command creates error plot3d:
