Drawing several 3D lines in one graphic?

[Javilón]

In principle my problem seems easy to solve. I know how to create the 3D graph,and how to set the number of plots available on the graph. My question is how do I specify "These data is plot1, these plot2..."? Cos all the data I put into the graph is represented in plot1.
Thanks in advance.

The following example draws 2 different plots on the same 3D graph (you have to specify the 'plot number' input to the '3D Parametric Graph' VI).
