Try specifying the glyph type explicitly see the glyph or autoglyph docs for details. A linear glyph such as arrow should work if you have the data as vector correctly (I think that is the default so there may be something wrong with you data formating.
Use the debug>print command with options set to rd to check the data is vector before you glyph it.

I basically want to make a 'kaboom' type 3-d distribution with the coords x,y,v_rad, since v_rad is effectively a measure of the z displacement from the center. The positions should be marked by an arrow which points radially away from (0,0,0), has a length proportional to the data, and optionally a color based on the value (bluer for positive, redder for negative values). Is this an easy thing to do? So far, all I've been able to do is: ImportSpreadSheet->(Mark x 3, for each value)->Compute (to make a vector)->Unmark->Autoglyph->Image but this only makes a distribution of circles, which looks nice, but isn't quite what I have in mind. Any suggestions?
