[Paraview] Color coding of a vector

[Xi Tan]

Hi,

I am new to paraview and I have been struggling with the color coding
problem. What I want to do is to color a whole bunch of cells by the
specific vector associated with each of them. The coloring scheme is to
set the x,y and z components as the (r,g,b) components, since I don't
like the default setting which uses the magnitude of the vector. This
coloring scheme seems possible since someone mentioned it in,

But I searched for quite a while, however, I had gotten the luck yet.
Anyone help me out?

Thanks in advance,
Xi Tan
