Question: How to build 3D plots with parallels linears fonctions


I have 5 docs with datas (x,y), like this one : BEF1txt

I want to put the 5 graphs side by side (parallels linears fonctions in a 3D graph). So I added the z data, z=1 in this case, and BEF2 got z=2, etc... But I am not able to make the 3D plot with the 5 linears fonction side by side.

May you help me please?
