I have three 3D arrays, P1, P2 and P3. They are the x, y and z components of a vector quantity (polarization). The position of the data in the array represents its position in the space, i.e. P1(1,2,3) indicates the value of x component at coordinate 1,2,3. I would like to view the data as something shown here, . The magnitude does not really matter here, what I would like to achieve is to group the vector quantities that are in the same direction by the same color. May I know what matlab function I can used to achieve this? I have tried quiver3 before, but it is too messy to interpret the plot. Thank you.

How to plot 3D vector data in color with vectors in the same direction grouped as one color?
