I second Andrews suggestion of IDLgrPolyline and XOBJVIEW:

IDL> len=1800
IDL> data = FLTARR(3,len)
IDL> data[0,*] = SIN(FINDGEN(len)*!DTOR)
IDL> data[1,*] = FINDGEN(len)/100.
IDL> data[2,*] = COS(FINDGEN(len)*!DTOR)
IDL> oLine = OBJ_NEW('IDLgrPolyline', data, THICK=3, COLOR=[80,230,200])
IDL> oMod = OBJ_NEW('IDLgrModel')
IDL> oMod -> Add, oLine
IDL> xobjview, oMod

XOBJVIEW's interface is a bit constricting but it may be all you need.
If you want to "get into" the flightpath, you know fly around the
flightpath, then you'll want to check out my camera. If you get to that
point, let me know.
