Let’s say, I have a field equation E = E(x,y,z) as a vector form. How do I plot field lines in root. Because for TGraphs I can only put f(x,y,z) =0 graph for 3D visualisation.

Thank you.

Yes sir, I am aware of it.

But the problem is let’s say E = e^2/(x^2 + y^2+ z^2)

I have 3 independent parameters along with one dependent parameter.

How do I plot the field lines then by 3 dimensionally?
