[Paraview] How to plot simple 3d graphic?

[Artem Babayan]

Hello,
Is it possible to draw simple a 3d graphic in Paraview? E.g. I have 2D
function f(x, y)=x^2 + y^2, I have generated input file with DATASET
STRUCTURED_POINTS. Now, what I need is to draw 3D parabola with or
without grid lines. Is it possible at all with Paraview? I have
managed to obtain 2D picture with color gradient only, by using
Surface representation style in Display menu.

Thank you in advance
Artem
