Hi guys,

I'm trying to display a vector as an arrow, but my best approximation
right now has been a cone. I'm using the following to visualize such

graphics top cone {-18.631001 2.933000 0.252000} {-18.088463 -0.328044
-20.981705} radius 0.400000 resolution 20

I would like to know if any of you know how to change such
visualization for an arrow. All comments will be greatly appreciated.
