Hi Overlord,

 

Actually 1/x² is a hyperbola. It is technically possible to create a 1/x nurbs curve with 3 control points, but you have to know exactly where to place them and what the weights should be.

 

Another possibility would be to create a range of numbers (say, 1000 numbers between 0.1 and 10.0) and use an expression to compute a Y value for every X number. Then you can create points from the original values and the values coming out of the expression and fit a curve (nurbs curve or polyline) through the points.

Hi,

Just as you said, you can use a function component :D
