Finding out the gradient for a set of points in three dimensional coordinates.

Hi ,

i am trying to find the value of velocity for a three dimensional set of points (X,Y,Z) , I have already found out he distances between the set of consecutive values and the points are in three dimensional coordinates.

I have the value of time as well between the consecutive set of points.Have a look on to the set of values in excel sheet attached.

Any help.Quiver plots are not helping me out showing errors.
