Streamlines of a Vector Field in Spherical Coordinates

How can I use the MATLAB 'streamline' function with spherical coordinates? in the function syntax:

streamline(X,Y,Z,U,V,W,startx,starty,startz)

instead of

X,Y,Z,U,V,W

I have:

r, theta, phi, V_r, V_theta, V_phi

Does this function care if data is in Cartesian or Spherical coordinate?
