[Paraview] visualizing particles with different radius

[sarai anvari]

I have produced *.vtk files which contain information about
6 coordinates in Cartesian space and radius of the particles. the particles
have two different type. type 1 with radius 1 and type 2 with radius 5. each
time i apply Glyph filter and choose sphere type only one  type of
the particles is changed. how is it possible to apply this filter to both
types or even if i had three type with tree different radii how could
i visualize these tree diffident radii?
thanks.
