[Paraview] drawing a 2D-plot: y=f(x) ?

[Martin Jørgensen]

Hi,

I have made a program that outputs the results in file0001, -002,  
-003, -004... etc in .vtk files (timestep solutions).

Suppose my geometry ranges from x = [0; 0.1] and y = [0;0.1], and I  
want to plot the 2D-function (z = 0), y = f(x) = 23*x^2 - 2*x + 0.05  
on top of my geometry, how would I do that?

I suppose I could make a program that makes some very small spacings  
dx and then I could probably connect each coordinate by a straight  
line... But there's probably a better method, I hope?

I don't know about this tcl/tk interface - perhaps that could be  
usen? I've no experience with tcl/tk, but somehow I think there must  
exist an easy solution to my problem....?


TIA,


Regards,
Martin
