Creating Interpolation Curve using Expression

Hi,
I want to create a 3D Interpolation Curve using an expression. For instance, let's use this simple example:
y=2*x
resulting coordinates would be:
x-y-z- 0;0;0 1;2;0 2;4;0 ...
I am trying to enter the expression "2x" in the "y" column (see image) but that returns a "x variable unknown" error. I obviously don't have the right approach.
Any suggestion?
Thanks, PL

With that expression you can set up an analytical function.

The doc on anlytic functions as well as interpolated curves is a bit thin. After making your analytic function, in Component-Definitions-Functions making sure to set the units appropriately, you could then call the function either by manually typing in an1(0), an1(1)... But I would guess that you want a smooth function. To achieve this, change the data source to vectors, and set a range for x, and then set (probably) the same range for y but this time choose the function at the bottom of the window. Hope the the screen captures help.

Hi all,
Using a Parametric Curve instead of an Interpolation Curve might be a better approach in this case.
Best regards,
