How to plot the electric field in 3D?

I want to draw the electric field lines in 3D. However I have the following Data:

1. - Ex (nx1): the electric field in the X direction as a vector data.
2. - Ex (nx1): the electric field in the Y direction as a vector data.
3. - Ez (nx1): the electric field in the Z direction as a vector data.
4. - X (nx1) the x coordination of the charges position.
5. - Y (nx1) the y coordination of the charges position
6. - Z (nx1) the z coordination of the charges position

By the way, n=10,000

" streamline" command requires 3D matrices which gives me ' out of memory'

Thank you for your kind help:)
